Re: Transmission issue
So I FINALLY got things replaced and MC back together. Special thanks to Lavoy for parts and knowledge he passed along to me. I've been using it in the woods and have about 8 hours on it without so much as a hiccup. Learning it's capabilities and limitations I have affectionately nicknamed it Mighty...

Re: Transmission issue
Would a quill from a 40 be the same as on an MC? Mine are both marked M812...on the 40 it's marked M812T.

Re: Transmission issue
Today I found the squealing noise I described in the original post in this thread. In the left side as seated, the repair manual refers to it as a "quill". The bearing there was completely destroyed. A chunk of the quill was broken off and even about a half inch of the race was missing! Does anyone ...

Re: Transmission issue
Lavoy,

Thanks

Re: Transmission issue
Finally got it home and in the garage. Took the gearshift cover off and drained the gear oil. At the bottom I found 14 rollers from a bearing but no bearing cage remnants. Bearings were ground up a bit but no broken pieces. I suspect one of the two bearings towards the rear of the input shaft. As I ...

Re: Transmission issue
From everything you guys have said I'm betting that's what the problem is. Replacements hard to find? Anyone make new ones?

Re: Transmission issue
Alrighty...took the cover off and all looked great. Slid 1st gear into place and it will start to turn the whole set but stops when the chattering starts. I'm guessing the splines as you described fundy. The reason I say that is the guy I bought it from had it all apart and stated the clutch was goo...

Re: Transmission issue
Thank you. I left it in the woods and am gathering tools now to go out and take a peek. Say the issue turns out to be in the trans...the book I have shows I should be able to pull those internals out the rear. I'm hoping it's that easy...but it's me.

Transmission issue
I bought a '49 MC from a great guy in eastern Kentucky. Runs like a sewing machine! He put new steering clutches on both sides and several other things. Just a great little machine for what I'm working on....nothing big. Seldom pushing more than half a blade full of dirt. When you release the clutch...
