A couple of weeks ago I bought a 1998 Fleetwood bounder 34V. The seller told me he'd had the starter motor on the Onan Marquis 5.5 genset replaced by a Cummins dealer fairly recently. However, the generator still made strange noises when starting, and sometimes wouldn't start.
Couple of days ago I tried to start it, and it jammed up. So, yesterday, I dropped the genny and removed the starter motor. It tested fine on the bench, and the generator was easy to turn over. I looked inside the gear housing, and found this....
Parts of the drive pinion of the old starter just left inside. Jeez.
Removed them, reassembled it, and it works fine.
How does a dealer just leave broken parts inside the generator???
