I just bought a 78 W200, first Dodge truck. *Pics added*
« on: December 29, 2011, 10:54:31 AM »
Hello, I just bought a 78 W200 last night, it's my first Dodge truck. I've been reading a lot of posts here trying to learn about common problems and fixes but there's a lot to read!
The truck has the 360 with a holley 2 barrel. 4 speed tranny with granny low. All time 4wd of course. 4:10 gears with an lsd in the rear. It's a strong truck for sure, I wanted it to tow or haul not to offroad, unless it's getting firewood or something. I plan on putting on or building a dump bed kit for it too. Has anyone done this? DIY or did you buy a kit?
One of the first things I need to fix is to replace the oil pan gasket. Can I get the oil pan off without lifting the engine?
Then it's getting it to run right. It has a "reman" carb on it. A previous owners ebay score so I don't know if it's set up right or if it was messed with. It runs crazy rich, stumbles when I try to accelerate, a lot of pinging too. I can see a lot of gray smoke from the exhaust when I floor it while it's pinging and trying to accelerate. What are my carb options for the stock manifold? What will bolt up? I have no problem with using an adapter to mount a different carb. I'm not sure if I want to swap the manifold for a 4 barrel or not. I'm not after as much poer as possible, I just want it to run right. With the low gears, I don't need a lot of power to do what I want, so a carb that provides good fuel economy would be nice.
What's the timing supposed to be, the info I found says 0 degrees...
One more thing, this truck has no catalytic converters on it. It's just straight pipes from the manifold to two mufflers exiting before the rear wheel wells. Is it supossed to have cats or not for a 78? i ran the vin and it weight class is 6001 to 10000 lbs, and the title says the gross weight is 8000lbs so maybe the weight class makes it exempt??

Thanks for your help.

 You will probably get more fuel economy with a small CFM 4bbl as apposed to the 2bbl, and a little more power to boot.

 I did when I took the 2bbl off my 79 360. I also did an ignition upgrade using GM ign module and ford coil.(that upgrade is somewhere on this site.) If your running old stock ignition parts-expect issues!

 Tune-up,timing. Can also cause pinging.....

 Sorry can't remember if the engine has to come up for pan removal, nor do I have any ideas as to the dump bucket.  Someone here will though!!

Thanks for the replies, I will get some pics up in the next week, my attention is now on selling my S10 so I can focus on the Dodge(and to have money to use).
I'll look for the info for the hei ignition, I did that on an old ford I had and liked it a lot.
The previous owner replaced the distributor wires and plugs, timing set, water pump and the carb. But I see the ignitor, or ignition box looks old.  The plastic cam for the fast idle is broken, gotta find one of those.
Once I find my timing light, I'll check the timing. I haven't needed it since the last 4 vehicles I've had didn't have distributors...
 
I've read that the stock 360 4 barrel manifold flows pretty well, is that true? Is it worth it to just get one instead of an aftermarket intake?

What tranny and transfer case is in this truck? Or at least, what oil should I put in them when I change it out? Motor oil or gear oil?


thanks

Here's a quick picture from the kitchen window..




all the trim is in the bed, I'm not sure if I want to put it back on or not.

Oh yeah, How available are 16.5 inch tires? the ones on it are 6.75x16.5.

16.5" tires can be had, but they're getting pretty scarce.  Keep an eye out for some 16" or 17" wheels you can get cheap so when you need new tires, you'll have a better selection.

The engine pinging and the running rich maybe just a timing issue.  The pinging certainly sounds like that anyways.  I would also bet that some of the running rich could also stem from that as well.  That would be where I would start anyways.  Great looking truck.

Yes the stock 360 4bbl intake is one of those rare animals that flows better than 75% of streetable junkyard/swap meet aftermarket intakes available for a 360.

With the 16.5"s, I found that it'd be cheaper to get new wheels and get tires for those.

You don't necessarily need HEI but a good solid working ignition is good. Making sure you have compression on all 8 would be a good idea too- that'd show if you're running like crap is from cyls down or not.

Not a lot of choices for the 16.5 tires. Tirerack.com has some. Might want to check with Treadwright too, they do retreads on light truck tires, I got some for my Ford and I like 'em. I think they had some 16.5 tread patterns to choose from but I'm going from memory.
Otherwise I'd do like the other guys suggested and just find some 16" wheels.

Welcome to the Mopar world frank. Very nice truck as well. To answer your question from before, it depends on the Tranny and Transfer case. The NP 203 factory recommended fluid is 10W30 engine oil, the NP 205 is gear oil and the 208/241's were spec'd for ATF. Personally, I've run gear oil in my 203 and 208's since day 1 and never had any issues in the past 55K miles or so. You just have to make sure whatever was in there before is completely drained out. Same goes for the Tranny. I would drain it out completely and fill it with a good quality gear oil even if it had ATF/engine oil before.

As for tires/rims, my vote would be for the switch to 16's as well. The choices for tires new and used is no contest vs. the 16.5's.  As a general rule of thumb, stock Ford steelies fit everything. They have the large center hole (to clear a full floating rear or huge front hubs) and no random offsets like some of the Chevy's had through the years. The last thing you want to do is have to grind the center out of a rim you just bought or grind the edge off a caliper to get the fronts to clear.

The profile and height of the 16.5's looks good on your truck.  One thing about them is not many people use them anymore.  I've seen a few on the used sections on line .  Try craigslist .  We have Kijiji here and Ive come accross 4 adds in one week.  Welcome.

The tires on it now are 8.75x16.5 , they seem to be more available than the 8.00 tires. The 8.00 are 28 1/2" diameter and the 8.75 are 29 1/2". I have found that if I do go with 16" wheels, that the 225/70 16 are the same diameter as the 8.00 and 225/75 16 would be as the same as the 8.75.
I just don't want a shorter tire since the 4:10 gears are low enough as it is....

I'll make some calls to some big tire places on Tuesday and see what they can do.
Then I'll call some junk yards and ask about some 16" wheels.

very nice lookin 78, I wish mine was that straight :(. lol good find frank.  my78 w200 has the 360 2 barrel 4-speed ( New Process NP435 ) and AWD transfer case ( New Process NP203) that should be what your has also. to verify crawl underneath and wipe the grime off the ID tags for the trans and transfer case the model #s will be printed there.  as stated above the NP435 uses 75w-90 gear oil and the NP203 calls for 10w-30 motor oil. 16" tires are gonna be much easier and cheaper to find. 235/85 r16 or 245/75 r16 will be your two best options for price and closest size to stock.  If I'm remembering correctly timing on that motor should be 8 degrees btc (+ -) 2. whatever ignition ya go with just make sure ya buy quality parts and it should run like a top :).  again nice truck keep us up to date man we love project pics  ;D {cool}

I've read that those oversized tires can eat up the wheel bearings on this all time 4wd axle, but thanks for the suggestion.

It indeed has the np435 and np203. It's also supposed to have a limited slip differential in the rear axle, but it looks like the axle has been changed at some point. I'll have to wait until I pull the cover off to change the lube to find out for sure.
I hope to have more pics up this week, the weather here is nasty today so it's gonna have to wait.

With the stock 2bbl intake, your carb choices are pretty limited. Stock 360, 4bbl intake is a good choice if you can find one otherwise a low rpm, alum aftermarket may be just as cheap and work as well. Edlebrock Performer was my manifold of choice. I topped it off with a 600cfm, vac sec Holley w/ electric choke. A set of headers finished the external bolt on stuff. Your truck may have squeaked by without needing cats due to the GVW rating in 1978. Start with a good tune up, cap, rotor, wires, plugs. Make sure the vac advance on the dist is still working, they can rust up and quit. Easiest wasy is pull the dist and work on it on the bench. Not a hard job and ALMOST impossible to get it back in wrong provided you dont rotate the engine. Plan on bailing on the 16.5 rims, dinosaurs now and tires have few choices and can be expensive. Change all your fluids and pull the front wheels and lube up that full time 44. Lotsa people miss that little job and end up cratering the bearings, which has resulted in most people condeming the FT setup. I have over 300k on my truck and am only on the 2nd set of front wheel bearings. The 203 is tougher than most people give it credit for and can easily be converted to a part time transfer case for just a few $$$. The 435 is pretty much bullet proof, keep clean oil in it. remove the vents from your diffs, thread a barb fitting in the hole and run the vent hose to higher ground if you plan on any deep water or mud work. I could go on and on but this should keep you busy for a while. ;D

By all means, keep going  :)

I called around to some scrap yards and 16" wheels are too expensive from them to be an option right now, and there are none in the classifieds right now.
I called some good tire shops and a local one that I go to often, Reeds Tire in Stanley VA, has some Firestone Transforce 10 ply 16.5 tires. Mounted and balanced for $159 each.

Not an all terrain tire, but with the all time 4wd, I doubt I need all terrain tires....
I'm going to keep looking in the mean time, I still have to sell my S10 first before I dig into the Dodge.

The weather is better today, no ice cold wind so I snapped some quick pics. It's as it was when I brought it home.
Notice the rust spots, the spot on the bed where someone tryed to fix a dent  ??? I would have left the dent. And the oil under it form the bad oil pan gasket leak. There are a few small holes in the floor, nothing major. But I'll have to fix them before I get it inspected.
And the tailgate actually works!!

as far as acquiring 16 in steel wheels goes.  I don't know if there is a u-pull junk yard near you or not. but where I'm at there's one I frequent that always has these old first gen trucks and they charge $7 per wheel. all ya got to do is go in and u can pull them till the sun goes down or ya run outa cash, lol. but that may be another way to go if ya can find a good u-pull near by

Thanks  :)

I plan on changing all the fluids, and I did see in the owners manual(still in the glove box with the build sheet) where there's a hole in the rotor to get to the grease fitting for the wheel bearings, that's cool!

A friend of mine may have some 16" ford wheels around the farm, I may have some old 2 stroke motorcycle parts left to work a trade  ;D

I started to call around to some junk yards, but the first place I called said $50 a wheel  :o So I stopped calling at that point...  The you pull it types that charge much less are too far away.

Well, in the last two days I got a little further. I put a new Mastercylinder on it, as well as a new steel line on the rear axle. When the previous owner changed the axle, he flattened it. My wife helped me bleed it all out afterwards to get the old fluid out. The pedal is still soft and goes almost to the floor before the truck stops, which is how it was before. But the master cylinder was rusty and gunky inside and too cheap to not replace it. I did bench bleed it. I think the problem may be in the back brakes, I heard a lot of movement back there while bleeding them. I can't check the movement with the parking brake because the intermediate parking brake cable is missing. Something the previous owner didn't put back on I guess. I think he swapped the rear axle with the one on his dodge to get the trac-loc differential. This truck should have it but while spinning in the mud(my VA clay yard) I could see that only one rear tire spinning.......

I got the choke to work, or at least work better. It wasn't working at all before because it was unhooked from the choke thermostat, and the plastic fast idle cam was broken. I got a cam off Ebay, and hooked the linkage back up. It starts right up like it should but the choke thermostat doesn't pull down to open the choke up so it stays on fast idle. I see that the choke pull-off, the vacuum diaphram, is pulled all the way and that gets it about half open, but the rest I guess is in that thermostat, the one down on the manifold. I've seen these with a wire going to them, but this one does not. Is it supposed to be electrical?

I replaced the oil pan gasket yesterday, that was more of a pain then I expected! I got exited when the pan basically just fell off when I took the last bolts out. But what I didn't realize was that it fell out because of the missing front rubber gasket. So I put the cork side gaskets on the pan, the rubber front one on the pan, but the rear one on the engine, and lifted it into place to find that with the front rubber on it, it will not clear and the rubber falls off. So I took it off and got the pan close and installed the front rubber after it was up and almost in place using a paint can to hold it up. I got a bit confused when I put the rear rubber on the pan and could see that it was too long, but before I freaked out, I tried it's fit on the engine and it was perfect. It popped into place and held there actually. After a new filter and new oil I started it up and drove it around the block(country gravel road) and checked for leaks, none yet!

I did see while under the truck, that the drivers side inner wheel seal is popped out. I could pop it back in with my fingers but that's goint to need some attention. What's the procedure to get to that? Press out the ball joints to remove the spindle?
I also found a hole in the exhaust that I'll weld up later.

I thought about the dana 60 rear disc swap since I will most likely replace all the brake parts in the back, other than the drums. But I like having a parking brake, and those calipers are too pricey. Anyone do it with different e brake calipers?

Not to beat the tire and rim issue to death but consider this if 16" rims and tires are not yet within your budget:  My old W-250 and W-350 both had 9.50 x 16.5 tires.  For your gear ratio of 4.11 they should be a good match. 

Sam's Club (possibly Costco) used to offer a "commercial tire" (more of a highway tread) in both 8.75 and 9.5 sizes.  IDK if they still offer them anymore but it may be worthwhile to check. 

If I were switching to 16" tires, I would go w/ a 235/85/16 tire as mentioned elsewhere.

It's not that the 16" tires are out of my budget, I will be getting new tires either way, it's just that I don't want to spend a whole lot on the wheels. I would rather have the 16" tires just because of the options. Like you mentioned, the only 8.75x16.5 tires I can find are the 10 ply commercial tires that are more of a street tire. I have more to do before I get to that anyway, so I may fond some good 16" wheels.

I worked on the truck some more today.
I pulled the axle out enough on the rear axle to see what kind of nut was in there so I could get to the back brakes, and it was a big hex nut. I picked up a 2 1/2" wheel bearing socket at Autozone but it wasn't big enough! Anyone know what size socket I would need ?
Since I hit a dead end on that I turned to the engine. It was acting like it didn't have a thermostat in it so I picked one up. It turns out that it did have one. But I replaced it anyway. It needed a new gasket and some better antifreeze anyway. I put a 180 in it.
Next I dug out my timing light and checked the timing. It was like 14 or 16 degrees btdc! I couldn't even see the mark on the balancer until I started to move the distributor. I set it at 8 degrees. I had to adjust the idle speed and mixture screws for it to idle. I started with the mixture screws at 1 1/2 turns out, and turned them in about 1/4 turn by the time I was done.
I had a new tachometer that I initially bought for my skidloader, but it ended up on a shelf. So I put it on the truck today. I needed to know the idle speed to set the timing so it worked out great.

I took it for a ride up my road, and it does run better. There's still a stumble when I get into it, but that may be the accelerator pump. I have the linkage in the top slot. I'll move it down one or two slots and see if that helps. I'll have to wait until I get it registered to get it out on the road and see how it does at speed.

I did notice a couple of things while setting the timing, that the coil is getting really hot! I couldn't even hold my hand on it. Is it suppossed to get that hot ??
And the tach needle jumps a bit, at any speed. It may just be that the tach is a cheap one but I've used them before and it didn't jump around. Is this a sign of a bad coil or ignition?

That piece on your manifold is called a 'choke stove'...I believe they are supposed to work off the temperature of the intake manifold to open your choke...my 78 with a 360 had one also, and it didn't work right, and I got the black smoke puff when I revved it up too...the choke stove wasn't working right, and when you would step on the throttle, it would pull the choke shut, making it run rich...either replace the choke stove or put a manual choke on it, should fix it...and running bigger tires isn't near as hard on wheel bearings as running rims with the wrong back spacing ;)

Thanks for the replies.

The choke stove isn't retracting the choke. I can hook it up, and the choke closes, and pulls the fast idle cam into position. The truck starts right up and doesn't stall. After letting it run a bit, I can blip the throttle and the choke pull off, the vacuum operated piece, will open the choke up but with the choke stove not retracting, the choke only opens maybe 1/4 of the way. So what I've been doing is leaving the clip off of the linkage from the choke stove so I can slip it on to start the truck, then after it's warm I'll slide it off. Yesterday I had it idling and up to temp for maybe an hour while messing with the timing and checking the thermostat operation and even then, the choke stove didn't retract. It look new but I haven't taken it off to check it yet. I have a manual choke cable in the shed that I can rig up.

Right now I'm trying to get to the rear brakes, I think I need the 2 9/16" socket. And no parts store around here has one. I'll try to get one online and hope it works.
I just want to get everything done except the tires before I sell my S10. The tires and inspection will be done the same time. The choke deal isn't a priority yet, but the brakes, the exhaust leak, and some small holes in the floor, need to be done before I get it inspected.

think the axle nut socket you need is 2 9/16". watch out, they come in 6 point and 8 point. use the socket by hand (no air gun) it's only stamped steel. mine came in a 3/4" drive, so you may need a socket adapter to torque it.

I just bought one on Ebay for $16.00 shipped  :o
http://www.ebay.com/itm/220691854598?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
The seller accepted my offer of $7.00.

I never bothered to check if the nut was 6 or 8 point. I hope it's 6 point.

I have to wait until it gets here to do anymore witht the rear brakes, but I have plenty to do on the rest of the truck.  ;D

Well, the socket I ordered worked, it was a bit loose on the nut but it worked fine.
When I got it all off I found that the brakes were way out of adjustment, the parking brake cables weren't even hooked up, and the wheel seals leak just a bit. The adjusters were frozen so I took them off and with a torch and some force I got them to turn. I cleaned it all up, greased the right spots, and put it back together.... brakes are perfect now!
I just ordered the rear parking brake cables because they were both frayed and beat up on the ends, and a couple wheel seals. Next week I'll get that done and change the gear oil in the axle.

What is the proper torque for that big 2 9/16" axle nut? They came off with 40 ftlbs so thats what I put them back on at. Any more and the bearings are too tight.

I also figured out my choke issue, I looked up a choke thermostat on several parts sites and they all show the electrically heated thermostat, the one on my truck isn't. I'll pick one up later.

The torque spec is a minimum of 100 ft-lbs, Frank.  If the slots in the nut do not line up with the cotter pin hole in the axle end, continue tightening until it does.  NEVER BACK THIS NUT OFF!!!

There is no bearing preload associated with this double-tapered wheel bearing set.  Proper bearing clamp is achieved by torquing the six bearing retainer bolts to 30 ft-lbs in a criss-cross pattern.   ;D

Well, I just found it in the Haynes manual, and according to that, it's like any other wheel bearing nut. Tighten it until the bearings drag then back it off a bit.

DO NOT RELY ON THAT HAYNES MANUAL.

Get yourself aan actual shop manual. I fowever carried the Haynes and Chilton manuals in my truck so folks would know what to do. Case in point the wholes in the front disk you mentioned, and it does not help. The shop manual tells you how to do it right.

Now, let's be sensible, I will be glad to take that POS off of your hands and you will forego all the pain and agony. Now, where are you?

Were you talking about the fronts? I haven't gotten to that yet  ;)

I need to tear into them at some point. I noticed the inner wheel seal on the left side was popped out.

 You are going to have a grand time with the front wheels I can assure you of that! If you know someone who has done them before be nice to them, you will probably be asking them a question or two.  These old dodges are tough! My 78 W200 has been there and back with me many times thru anything nature wanted to throw at us and it brought me home every single time! A few times it wouldn't leave the driveway the next day until I fixed whatever broke, but it never stranded me and thats partly why I have kept it for going on 27 years now. I have fixed about everything on it twice  except the differentials and the transfer case and if they ever need it I spose I'll fix them too..  If you have half as good luck with yours as I have mine you will love that thing!  Good luck and avoid big bumps..  the only thing you'll hurt is yourself!

Well, I worked on it some more, and it ended in dissapointment   :(

I got some parking brake cables, and wheel seals and tore into it. I got the drivers side apart and pulled the wheel seal out, and before I put the new one in I decided to clean the bearings of the old oil and put a light coat of grease on them for reassembly. I have some gear oil and a cover gasket to change the oil in the rear and was going to do that last before I drove it away. Well, the bearings and the races were pitted bad. So i went back to town, and between two different parts stores I got 4 bearing sets, 2 per side. I got the drivers side back together with the new parking brake cable, wheel seal, and bearings installed. I cleaned the big nylon nut, and the axles bolts well before reassembly. I also replaced the paper gasket on the end of the axle. When I got into the passenger side and when I wnet to loosen the big nylon nut, which I've had off several times allready, it got halfway off and got tight. I knew what that was so I turned it back on and cleaned up the exsposed threads and the groove in the tube for the locking tab and found some metal. I have damaged threads. I hoped it was just the nut so I tryed again, same deal, it got tight. After a couple times of cleaning and turning it came off. Half the threads on the nut are gone, and some of the threads on the axle tube are flattened. I may be able to clean up the threads on the tube with a file and a hacksaw blade, been here before, but isn't that nylon nut unavailable now???
I don't know If I can trust it if the tube theads are damaged.

So I put the parts in the cab and walked away until I can resaerh it some more. I may just change the whole axle now, If I can find a deal on one.

I got the rear back together.
It took some time to find a thread file, I went to 4 different parts stores and the last one was the only one where the guys knew what a thread file was! It's always good to see some old guys behind the counter when you walk in!
Anyways, I cleaned up the threads, installed the new bearings and seal, hooked up the new brake cable and put it all back together. I opend up the left side again to replace the nut and lock. It's obvious how worn out the old nuts are when you put a new one on. What a difference.
I just made up a piece from scrap medal to hook the 3 brake cables together. I works, but I need to redo it. Once I find the right part, or a picture of one, I'd redo it.

I had to replace the alternator yesterday. I borrowed a friends Ford while the powerwagon was sitting on three wheels... but when I went to start his truck to take it back, it wouldn't start. I think it was just a bad cable and corrosion, after cleaning it up I swapped my battery and one cable onto his truck to get it back to him. I charged his battery, then took it back for mine the next day. I got two new cables for my truck and put the battery in it. It then sat for over a week without running. I went to start it and nothing. I charged up my battery and the truck started and ran better than ever. That got me thinking and checking the electrical system and I found that the alternator wasn't working. After having it tested, I replaced it. Everything works better, lights, ignition, starting, etc.

Also since I posted last, I bought a new choke thermostat for it. I got an electric one. I noticed on the harness that there was one wire near the carb that wasn't hooked to anything. It had 12V while running, and nothing when off. So I used that wire for the choke. After a few adjustments to the linkage, it all works fine.
I got one from here,

If, sometime down the road, you decide to change those front fenders, be aware that there are two different lengths out there. By 1/4", but enough to ruin your day. Measure them towards the top where yours change colour.
