Let me first say I find this site to be awesome and a valuable resource. I have been using it unregistered for a little while and decided to join today.
I recently purchased a Case MB4/94 U900 406 that was not running. The owner unfortunately passed away a year ago and he left quite the mess in regards to wiring. He was a farmer and there were quite a few "farmer fixes" under the hood. The mice also made themselves comfortable over the past year in his absence. It had been sitting outside without the hood.
I'm not one to shy away from a electrical challenge and dove into things. After running a few jumpers I was able to get power the critical components needed to attempt to start the Mog. With the clutch pressed I pushed the starter button...... The solenoid clicks and the starter motor fires up, but it is not cranking the engine. I let go of the button and the starter motor decelerates. I try a few more times and it's evident that the starter gear is missing it's teeth or it is not shooting out to engage the fly wheel.
I'd like to know what you guys think. My plan is to remove the starter after I figure out how to tilt the cab and bench test it. Is there a starter rebuild kit or should I go with this gear reduction starter off ebay:
New Gear Reduction Starter Fits Unimog U 800L U 900 AZJ3299 MT66BA 5001836 11360 | eBay
The price seems a little too good to be true, and I'd like to stick with OEM stuff. Has anyone rebuild an original starter or used one of the eBay gear reduction starters? The ad says they fit a OM353, but I imagine they fit the OM352 as well....
Let me also say that the battery is a new Optima blue top and it's also hooked up to a 100A charger/jump starter. My other though was that the fork that moves the gear out into start position is stuck? But if that was the case I don't think the starter motor would move, correct?
Thanks in advance for the help.
Anyway, here's some pics. I can take vide of the problem if needed and post it as well.
