How To Shorten Comer PTO Shaft?

[HobbleCreek]

I also have a Comer PTO shaft on my snowblower. The little book that came with mine included instructions for shortening the shaft. I just happened to be looking at it today trying to find the correct size for replacement shear bolts. That wasn't there, but instructions for shaft shortening were.

I tried to scan them and post them, but I'm having some difficulty. The steps are pretty simple, and are pretty much what has been said already:

1) Remove Shielding

2) Shorten the driveline tubes to proper equal length (very helpful instruction, eh? The picture shows a hack saw cutting the tubes.

3) Debur edges of the drive tube with a file and clean all filings from the tubes.

4) Shorten the equally long guard tubes to the same length as the driveline tubes. (I think this is a translation from Italian, but you probably get the idea.)

5) Grease the internal driveline tube.

6) Fit the guard on the shaft.

7) Make sure that the length of the driveline conforms to the maximum elongation conditions. (I have no idea what that means.)

#7 means make sure that the max length the implement can extend the PTO shaft will not cause the shaft to come apart.

I.E. make sure the shaft is not too short before using as if it comes apart it will be "unpleasant".
