Wiper motor refurbishment

Hi Chaps.
Just been sorting a few issues out on the TF.
When I first got it I noticed the wipers were really noisy and slow.
I took the wiper system out this morning.
Removed the motor cover and out fell about a tablespoon of water. Cleaned it all up and sprayed it with SGB and got some waterproof white grease into the gearbox.
It's now much faster and quieter.

The cover is retained by two Torx screws, take those out and pull the cover off. There is quite a strong magnetic field that will try and pull the cover back but don't worry just pull it off. Clean everything but do not mess with the 3 little brushes at the bottom, they are delicate. Give the commutator, that's the segmented part the brushes touch, a good squirt with SGB (WD40 will do at a pinch) and put some waterproof grease into the bearing at the bottom of the cover and reassemble.

At the other end of the motor is a small plastic end-float screw, take this out and squirt some waterproof grease down the hole, re fit screw and nip it up very lightly then back it off by about 1/4 turn.

The screw has a 'split slot' head but a very small screw driver will fit one of the two slots or better still is a pair of small circlip pliers.

Mine was filled with rusty water......scraped that motor.

That's the point, it's a damage prevention exercise.

My original was actually full of rusty brown water and the commutator had disintegrated!
When i fitted a new one, I went all high tech in waterproofing and taped a plastic bag over the motor! Never had an issue since. :lol:

Just drilled a hole in mine at the bottom to let the water out simple :woohoo:

Hey mate, I know this post is quite old now but just wanted to say thanks for sharing this because it really helped me today. I had the same problem with my TF wipers being slow and noisy. I took the motor apart and found water inside just like you said. I cleaned everything, sprayed some contact cleaner, and added waterproof grease to the gearbox and bearing. Now the wipers are much smoother and quieter. That part about the strong magnet on the cover and being careful with the brushes was spot on. Appreciate you posting this back then, still useful after all these years.

I had the same problem with slow and noisy wipers on my TF and found water had got into the motor. I removed the cover with the two Torx screws and about a spoonful of water came out. After cleaning everything, I sprayed the commutator with SGB, put waterproof grease into the gearbox and bearing, and the wipers are now much quicker and quieter. Be careful not to touch the little brushes as they are delicate. At the other end of the motor there is a small end-float screw, I removed it, added a bit of , tightened it lightly and then backed it off a quarter turn. It turned out to be a simple job that makes a big difference.

That is a brilliant first post. Welcome to the forum

Please excuse my ignorance - what is SGB?
