How to disassemble, clean, rebuild, and reassemble trim motors

[BlueFishCrisis]

A lot of effort went into preparing and documenting the rebuild process. Nicely done, all around!

Polaris called all their electric trim systems Quick Trim. The gearbox documented here is a regular speed trim system, which Polaris labels as a 3 RPM unit in the parts cross reference.

The 'fast' trim gearboxes run at roughly double the speed of the regular speed trim. Polaris labels these as 6 RPM trim motors.

I think somebody pulled one apart a while back and posted photos of the internals.

Perhaps some day day a similar thread can be done for the fast trim motors. The Pro and SLX owners would be appreciative, I hope.

Thanks for the great 'how to', it enabled me to get it all apart and cleaned up last fall. I finally ordered the new motors last month and the shaft on them are different as you mentioned with the first 1/8" of the shaft ground flat. I pushed the pinion gear on to the new motor shaft and it just spins and I'm not sure how I'm going to make this work now. The shaft on the old motor seems to have grooves forced into it to keep the pinion from spinning. I could reuse the old motor because I was able to get it working on 12V power again, but I'd rather not because it's rather corroded.
