G'Day Gents - Maybe some of you have done the 'trick' of reaching in the starter opening in the bellhousing to dress up the ring gear?
The situation is that my heretofore poorly maintained 490D has a ring gear that is at least half missing/smashed/mangled - and I'd like an idea of a tool that I could 'reach' into this opening and grind the remaining gears to a slight angle (instead of the present bluntness), so as to defer pulling the motor. Thoughts???
More background: The situation is that I had a bad solenoid stud on the Densi (sp) starter, the shop would not sell me just the stud... "Okay fine, rebuild the whole thing". When I went to install it, I was aghast when I glanced in the hole! :Pointhead I mention this as the starter is in perfect working condition - but regrettably, 4 or 5 times out of 6 try's, the starter will just bang into the ring gear instead of properly engaging... this cannot continue, and will rapidly get worse.
I do not want to pull the motor, having only moved a few tablespoons of dirt, and invested thousands on this new-to-me machine.
Assuming I can find some sort of air tool, and reach in there, four additional questions present themselves:
~ Do I grind on both sides of each tooth (minimizing the removal of steel of course), or do I 'slant' it to better receive the starter drive?
~ Assuming slanted would be better, would I slant it opposite of the starter drive tooth angle???
~ Can I safely turn the motor over with a small flat bar by prying from the side of the starter opening (with the throttle all the way forward/off)?
~ Maybe I should pointy up my starter drive??? (A lot easier to replace this, than yanking the motor!)
My exasperation on the prospect of removing the engine (or maybe just the pump?) is exacerbated by the fact that my farm is out in the sticks, and the mud - meaning just hiring a service truck to get in here may be a challenge. Therefore, thanks in advance for those of you who will provide some thoughts on how to jury-rig the situation, rather than 'doing it right' at this time. (The machine is just short of 10,000 hours, but purrs like a kitten - but at some point I will have to rebuild her...)
Thanks again!
