I have a 1967 Fj40 with the independent motors. These are on early- 1967. Mine were starting to make a lot of noise and I was worried they were going to gum up and seize. I have seen threads on these where the poster didn’t take out the gears but rather cleaned them up the best they could. After opening everything up, I realized they were super simple to take apart. I took a ton of pictures and documented everything I could. Here are some of the photos I have and directions on how to disassemble and reassemble your wiper motors.
You will need the following: mineral spirits and brake cleaner for the gear box, QD electric parts cleaner for the motor side, a good white lithium grease (not that BS spray), lots of Q-tips, rags, a few small screwdrivers, and patience. Overall, it’s pretty easy. Just take a ton of pictures and work on one side of your motor at a time. FYI- Lose one of the screws and you’re hosed as they do not exist anymore. Some of you early model FJ40 owners know what I am referring to.
DISASEBLY
1. Here is one of my wipers. They both looked like this. Before I removed anything, I used something to scratch off the grime without scratching the housing. I did NOT use any water near this thing. I used mineral spirits on a rag to get rid of the grime and then used some brake cleaner ON A RAG to remove any left over residue that might have been left.
2. Once the outer side was cleaned up, I removed the two side screws (again, don’t lose them) and cleaned the inside of the housing and the motor with the QD electric parts cleaner. This is what it looked like once it was clean.
3. When I first removed the backing, here is what it looked like. I used a bunch of q tips to remove the majority of the old waxy grease before I disassembled. At this point I removed that gold looking over that is being held by a single screw. The gears are on posts so when you remove this, nothing will happen.
4. Here you see three gears… that’s it. Note the position of the arm thing before you remove it. I would put it back in the exact same position later. Simply remove the gear on the right by pulling up. Next, the larger one with the arm is tricky but not hard. I am pointing to a spring loaded pin that the gear sits underneath. You need to push it back with a little screw driver while popping it up from the other side. It will take a minute to get the hang of it. Under that gear is a thin washer. DO NOT lose this. The third gear to take out is the one in the middle. Just pull it out and your housing is completely clear.
5. This is what mine looked like after I used some soaked q-tips in mineral spirits and gently removed the old grease. I used a rag with brake cleaner the clean the inside of this housing and the 3 gears.
