C Clutch Issue Resolved (mostly)

All,

Some of you may recall my posting from a week or so ago in which the clutch on a rebuilt '50 C seemed like it wouldn't disengage fully...

Well, I have new results to report! (Most of 'em are good...)

Big Don was right. When I blew the installation of the first engine, I bent the clutch disk. It was pretty clear once I got it out. I installed a new disk, made sure I had greased the pilot bushing, and put the tractor back together again. The clutch now works great!

For those interested, I've uploaded a couple of pictures of the bent clutch disk:

It was bent to the extent that the inside hub was rubbing against the flywheel bolts.

The bad news is that, in addition to the clutch disk, I bent the drive shaft too. Not a lot, but enough so that I could see the end bounce around when I had a neighbor rotate the PTO shaft. I can feel the vibration at higher RPMs... So, I'm now noodling over whether or not I want to find another shaft and swap it out. Anyone know if I have to remove the clutch housing from both ends in order to do that?

So, thanks for everyone's input -- the C is back in business! (And, I'm getting really much better at putting a split tractor back together the *right* way.)

You only have to split the tractor in front of the transmission to remove the drive shaft. You take wires rods and all that stuff loose at that joint, support the front part (solidly!! I used a support I made out of 6x6 timbers bolted to the holes on the clutch housing). Then you will need something to hold the rear part. When you split just in front of the transmission, the back part is nearly balanced, so it does not take anything real heavy, but you need something that will let your roll the wheels and transmission back. I used a shop lift(engine lift). Once you have it all supported, take out the four bolts at the joint. I suggest replacing with longer bolts until you get the joint loose. Pry the joint apart, roll the rear part back and the drive shaft will come out of the clutch, etc. Make sure the clutch remains engaged, or you will not be able to get things back together. Also there are two dowell pins in the joint in addition to the bolts. Make sure those are not lost and are put back. Now you can take the flex joint bolts loose and take off the drive shaft. There are rubber washers with metal holders on the flex joint bolts. The bolts are tapered shoulder bolts and can be difficult to break loose and get out. Hope this helps. Good Luck!! Also while you are in there, check the transmission shaft seals and replace them if needed.
