Selectrim Motor Rebuild

[Darringer]

I have a 1985 3.8l 800 drive with selectrim. My question is: Can I separate the selectrim motor from the pump while the pump is still mounted and the hydraulic lines still connected? I can physically get to the motor/pump. I need to replace the brushes in the motor.

undoing the hydraulic lines is quite simple. Just lower the engine all the way first. I have cleaned mine up before and I just pulled the whole unit out and then separated the motor on the bench.

How readily available are the brushes, How did you make out installing them?

Re: Selectrim Motor Rebuild

my brushes were like new. I just generally emery cloth the commutator bars shiny and use a seal pick to carefully tidy up the insulated separations between them.

Re: Selectrim Motor Rebuild

I pulled just the motor off of mine without removing any of the hydraulic fittings to rebuild it. I cleaned it all up and and shined up the commutator as Howard described and I put new brushes in as they were about 3/4 gone. Got the brushes from a local alternator/motor shop for about $15. He had some the right size in stock that he matched to what I brought in and I just soldered them on. Pretty easy job, and definitely easier than getting the tilt motor out & in!
