Starter Motor Problems

Post by JMD168 »

Fitted a new front crank shaft Oil seal and timing cover seal, built it all back up again, tried starting the engine, not much happening, struggling to turn it over. Checked the relay after cranking it a few minutes, I could just hear it clicking, put the volt meter on, it's burnt out. Cable to the starter motor was quite warm so it must have been getting plenty of power, better take the starter motor off. Dismantled it only to discover a lot of rust, no doubt for many years water has been getting inside to such an extent one of the springs that push the carbon brush onto the commutator had rusted away. That's why it it struggles to turn the engine over only three brushes in contact, so my question is does any one know where I can get another of those little springs from ? Any suggestions would be most welcome, please reply here or call me on 07984127060, thank you.

Ordered and received a couple of small springs that push the brushes onto the commutator. Fiddled around for over an hour trying to get the springs onto the brushes without pushing the brushes down the slot. Finally released the springs, with my hand inside the stator pushed the brushes well out of the way, fitted the rotor up to the brushes, then using small cable ties looped around the springs pulled them up, putting a small allen key through the cable tie loop, with the springs kept up under load and the brushes held up out of the way I slid the rotor home into the bearing, cutting the cable ties allowing the springs to push the brushes down onto the commutator, job done. Once I had come up with the idea of using small cable ties to lift and hold the springs clear allowing the brushes to be pushed well up the slots it only took 5 mins. Any one having difficulty with this job try using the cable tie method.

The big question, does the starter work now? Dave

Hello Dave, yes it does, it turns it over nicely and starts straight away. The band that wraps around to cover the port openings was in reasonable condition but the inner seal had disintegrated, I noticed an old cycle inner tube on one of my shelves, thought that will do nicely, cut a section out and fitted it around the starter motor then fitted the clamp, that should keep out the occasional shower.
