I'd see if I couldn't get some new brushes; I'm going blind so I can't see what kinda shape they are in. That and bushings.

Clean it down in something that WON'T dissolve the shellac on the windings and polish up the commutator with say, some 400 grit wet-or-dry paper and WD40.

Lube the bushings with some Green Grease (you can get it at Advance), slap together, and go.

The housing you can clean with some good brake cleaner like Advance Auto's Wearever Gold spray. It's made up mostly of heptane and isopropyl, and evaporates quickly and doesn't attack the shit outta stuff.

yeah, so the motor just turns slow. its got enough spark and gas/starter fluid. but the motor doesnt even turn over full speed. i've got plenty of battery going to it (12V charger, start)

hopefully cleaning this up will help a bit

A lot of guys I know will bench run their starters with a pair of jumper cables or a high-amp battery charger, and loosen the two long housing bolts a bit so that they can rotate or play with the brush holder end and get optimum rpms out of it. Snug up, bolt up, and go.

take a razor blade and carefully clean out the slots between the commutator contacts, then polish it with 320 grit sandpaper, spray it all down good with contact cleaner, then grease the bushings and reassemble it

i dont see any scarring on the stator magnets, so it doesnt look like its a mechanical issue, ie. dragging

[Edited on July 29, 2008 at 8:09 AM. Reason : now that i look closer, it appears two magnets have disentegrated]

7/29/2008 8:09:08 AM

yeah. the magnets look bad. one of then had a piece fall off without much handling. ill take all this advice... perhaps change the magnets also

this is not BS by the way

go to taco bell- get a bunch of packs of the hottest sauce they have and smear it all over the dingy copper contacts. let it sit a couple hours, wipe the excess then clean with electrical contact cleaner, electra-motive is good but the QD dries super fast and leaves no residue I think. those are available at advance auto, radio shack sells a can of cleaner with a brush attachment on it as well.

^ vinegar does the same thing, but a razor blade and sandpaper is quick and easy

7/29/2008 8:26:09 AM

Yep, a bunch of good info in this thread.

Definitely get some new brushes and align the Brush Hoods as best you can.

Clean out the grooves between the brass pieces of the Commutator and polish/true the Commutator as best as you can.

Use an electronics safe cleaner to clean both the Comm/Armature and the Can.

Grease/replace the bushings as needed.

Be careful not to crack the magnets in the Can when putting the Armature back in.

I've rebuilt hundreds of electric motors and even wound a few of my own (never turned out all that great since I could never get the Armature balanced perfectly). Back in the day we all had rebuildable stock/mod motors in R/C racing...now everyone's running brushless motors.
