Wiper Motor Gear
« on: June 25, 2016, 04:32:12 am »
Hi,

my wiper motor squeaks like a old rusted bolt. I disassembled it and found out that the plastic gear which is connected to the magnet motor gear shaft is the faulty part.
Although it is in very good condition ( no broken or rounded teeth ) it is kind of rusted or stuck to its shaft. This produces this awful squeaking sound during operation.
I found a replacement but I'd rather get the "rusted" or "glued" gear off the shaft without breaking it. Any ideas?
Furthermore i wonder if anybody knows about the 2 additional connectors on my wiper motor. Is it for the washing pump? See pic.
I know that the 4 Pins are for the basic function and the single one is for the intermittent function.
There is no information about in the FSM.
Cheers

Here is a link to the gear as i forgot to take pictures ;(

    Was not able to grease it up because the old grease was sticky and hardened inside the gear.
    I managed to pull the gear with a little wiper arm puller and a little screw. I needed a lot of power to pull the gear but finally it got free without destroying it. I then disassembled both halves.
    Cleaned the shaft with a rotary tool and sandpaper( it was a little rusty also ) and the housing and everything else. Greased it up.
    Now it is running like new without any squeaking sound.
    I also replaced the pop rivets with little screws so in case of future repairs it'll be a easy access. I also found out that my Dwell Switch is broken so i have to replace this as well.

    Here are some pics.

    Probably easier and cheaper to just get a replacement wiper motor.  What year is this for?

    itīs for a 1984 RC.
    I checked the refurbished ones from 1A Cardone but they look more like as if they are just painted black.

    Thinking more along the lines of junk yard or ebay for a good one.   Or find someone on here parting out a truck with one.

    Thanks!

    unfortunately I forgot to take more pictures of the total disassembly, cleaning & assembly.

    Here is a write down. Hopefully i didn't forget anything. If anything is wrong please don't hesitate to correct me.

    Disassembly:

    1. Disconnect Battery
    2. Pull the wires/plug ( plugs if you have intermittent option ) from the wiper motor
    3. Remove wiper arms
    4. Remove cowl panel

     ( i think it is possible without removing wiper arms and the cowl, but i did it and its not a big deal )

    5. Remove crank arm nut (5/16-18) from wiper motor shaft and remove wiper linkage and crank arm from shaft
    6. Remove the 3 bolts ( 1/2" ) that hold the wiper motor in the firewall
    7. Remove wiper motor
    8. Put wiper motor in a vise and drill out the factory pop rivets
    9. Prier out the metal spacers from the rubber mounting grommets
    10. I then cut sliced the rubber mounting grommets in half because i wasn't able to remove them by squeezing.
    11. Now you can carefully split the two halves with a screwdriver

    By splitting the halves the "pink plastic motor stop thing" with its spring and washer maybe will pop out. So watch out and remember in which position it was. In my case i didn't remember and i had to do it by trial and error.
    But it is kind of self explaining. So it shouldn't be a real problem.

    - Magnetic motor half
     
    12. Remove the 2 screws of the dwell switch and remove it ( if you have one )
    13. Remove the the 2 screws from the motor housing
    14. Remove the motor housing. It's magnetic so you may need some force.
    15. Just carefully pull the magnetic motor up. Be careful not to loose the washers or damage the carbon brushes and cables. It is washer, spring washer, washer.
    16. Inside you can now remove the plastic gear if its not "glued" or stuck to the shaft. If it is stuck use the little puller.

    - wiper linkage half

    17. If not already happened remove the "pink plastic motor stop thing" with its spring and washer from the gear.
     
    - There is a nose on the gear so it is kind of clear how to mount the "pink plastic motor stop thing".
    It's  "Thing" , washer , spring.

    18. Remove the shaft rubber grommet from the back of the housing.
    19. Remove the little retaining ring from the shaft by pressing down the washer
    20. Remove the washer
    21. Remove the spring washer
    22. Remove washer
    23. To remove the shaft from the housing you have to drive it out with a little hammer. Be careful not to destroy the copper bush.
    24. Now you can remove the shaft with the gear. There is another washer on the inside. Don't loose it.

    Tadaaaa... everything is apart. Now clean everything carefully and grease the gears.

    Assembly is just the other way round. To drive the shaft in i used a big tool nut and hammered the housing on the shaft.
    The whole install is a little tricky but after a lot of cussing & some beer it should be done.
    Install the dwell switch at last. Itīs a lot easier.
    Just replace the pop rivets with little screws. Install the wiper motor and enjoy the fabulous fast and smooth wiping.

    cheers

    Flo

    Have you tried LMC motors catalog?  They have wiper motors listed for RCC model years, 72 to 93,priced from $49. to $69. dollars.

    I just replaced my wiper motor today with one from the salvage yard. If its possible I could give you my old one. It works but the relay is bad so i had it jumped to a toggle switch before i replaced it. You could take the part you need out or find a way to mount your relay. The motor is only about a year old. Damn thing died on me. Don't buy parts from napa. My steering box also crapped out prematurely.

    with 2 fsm's wire diagrams , a '93 delay wiper motor can be wired TO the dash switch of an older 2 speed wiper truck . they bolt in , and "park" too . changes needed are right at the motor .  I had a '93 connector , so next time the required "part" is just a standard '93 motor for a plug and play r/r .
