I recently had my starter rebuilt at a local Auto Electric shop. After installing it back in motor I have had an intermittent issue. Sometimes the solenoid will click but starter wont spin, if I rock car in gear (rotating ring gear slightly) starter engages and starts normally.
I pulled starter and took it back to rebuilder. Today they tore starter apart and this is what they found. The bearing behind the drive gear has been ground off, obviously coming into contact with the ring gear.
When they rebuilt starter they replaced the drive assembly. We took measurements of the gear and the gap between the front of the gear and the stop. They were; gear= 15.25mm, gap=16.72mm.
The rebuilder thought the solution may be as simple as adding a shim behind the existing stop shown on the shaft. If you look closely at the shaft you can see a mark(line) around the circumference about 1/8" in front of the gear. He thinks that is where original gear was located, so he is thinking a shim of about 1/8" will cure the problem.
I have talked to Papajam about this problem. He had a .7hp starter on hand and was able to take the same measurements as mine. His were; gear 16.13mm and gap=13.3.
Papajam also thought there was supposed to be a shim between the starter and the bellhousing. He emailed me a pic of the shim out of the parts book. After looking at the pic, I am 100% sure my motor never had that shim. I have had the bell housing off on numerous occasions.
Now I am wondering if I have more than one problem. wrong drive gear and missing shim? I can possibly fabricate a bellhousing to starter shim, but does anyone know how thick this shim actually is?
Am I missing something obvious?
