Motor Mounts
« on: March 14, 2006, 04:09:34 PM »
This may be an easy question, but I don't know the answer.

Can the motor mounts be changed with the engine still in the truck?  I was thinking of just hooking up an engine hoist and lifting it enough to r&r the mounts.

Thanks,
Ted

Edit:  Oh yea how about the tranny mount?

Yes, I did it with a block of wood, and a floor jack under the oil pan.  the tranny mounts are the same, unbolt them, and lift with a floor jack.

Yes, I just did mine, but I used a floor jack on the bell housing of my tranny.
If you have access to an engine hoist, that will be even better. I suggest removing your distributor cap first and just keep an eye on your distributor so it doesn't hit the firewall.

I haven't done the tranny mounts in my RC yet, but I've heard it can easily be done.


Edit: you guys are quick!  ;) I thought about using a block of wood on the oil pan but I wimped out....didn't know if it would support it, now I know.

That's a good idea about the dist. 

As soon as the ground dries out (and I have the time) I'm going to replace them.  My RC shakes when in gear.  I had my wife power brake a bit and the motor/tranny moves.  The rubber insulators are all dry-rotted anyway.

I have just changed out my motor mounts last Friday. It was a pain in that even with my heads and intake off I still couldn't get the engine up high enough to pull the mounts out with out taking loose the brackets from the sides of the block after loosing the frame nuts and inner bracket nuts.  (dang long sentence! ) I used a block from under the dampner/belt pully assy. Figured that with all that extra dead weight gone that the pullys wouldn't be hurt jacking up the engine. 

All went fine taking loose the first bracket and positioning the motor mount and putting the bolts back into place on the ears of the block through the bracket. Then the jack shoved off out from under the front! REAL glad that my fingers were not in the way.  I was out front of the RC picking up a wrench to tighten the bolts up with my impact wrech.

If I was to do it again.  I WOULD use my engine hoist and have a lot less to worry about!

Please be careful which ever you do. Even a block with out heads/headers/intake is still pretty dang heavy. I'm sure that you won't take yours down that far to pull the mounts. Its still a lot of dead weight.

Yeah i've done it too. 3/4" socket with a short extension, and a breaker bar, preferably in half inch to take it off. No probs lifting up the engine enough to change them. I used my dad's old back hoe. I haven't had problems with the nuts backing off after it was done either.

If you use a 2 X 6 about 8 inches long on end on the vibration dampener you can do it.  The key is to understand from the get go that you have to disassemble the engine mount brackets from the block in order to get enough clearance to remove and install the mounts I did the passengers side first and once I figured out that I had to do this it went quite quick.  Hope this helps.  Ken Irwin
