Are B & CA belt pulley shaft taper different?

Grinding will not work because of shaft SIZE !!!!! Had a customer put a woods mower on his early B and I got the correct pulley from woods dealer .He later sold the mower and the guy that bought used the later pulley .

If u have another B sitting around for parts swap out PTO UNITS .

I dont know how "loose" the pulley is on the shaft.. If it is just a small amount, maybe you can grind the face of the pulley hub so the pulley will slide on a little further ?

The side that would need to be ground is already flush with the spokes.

The early B has a DIFFERENT size SHAFT I had both shaft size PULLEY's for the woods drive belt. will have to check shelf .

Your pulley hits the PTO housing before the nut is tight ? Is that the problem ?

Yes sir.

That drive pulley is on backwards like >< instead of <<. If the drive pulley was half and inch closer to the right it would work. I did speed the deck up to 1/2 speed and it stayed on like in the pic but I did not want to damage the $80 belt so I stopped.

#1 The taper on the belt pulley shaft for the B,C,CA and early D10/12 tractors is the same and the pulleys are interchangeable.

#2 if you have the manual for the WOODS belly mower, Carefully read and reread the section of the proper installing the belt with all the twists in the proper place. There are ways to put the belt on with the wrong amount of twists in the wrong place and it will immediately throw the belt off. When everything is done exactly as stated in the manual the belt will run just fine.

If it was fun to pull in LOW gear, I could have a John Deere.
If you can't make it GO... make it SHINY

This is on a 1938 Model B.

I bought a Woods 59 belly mower from a friend he had it mounted on a CA. He said it was built for a B and C, I have the factory Woods manual with it and it shows B and C in it. For the CA he built different brackets to make it work on the wider CA. I always thought C and CA were the same? We have a CA. I have never been around a C.

I took his brackets off and everything bolts right up to my B.

The only thing that does not work is the pto pulley. It seems the shaft on my tractor is too small the pulley goes on too far. I needed to use the mower so I flipped the pulley backwards just to see if it would work. By hand it works fine but once I turn the pto on slowly releasing the clutch the belt starts coming off because the drive pulley is not lined up right.

Do they make tapered shim bushings or can I use some shim stock? Or do I need to find a different woods pulley? I dont have any shim stock but tomorrow I might attempt to ghetto fab it with some gorilla tape as a shim.

I didn’t measure the shaft or factory flatbelt or woods pulley tapers yet but will tomorrow.
