1968(close enough) Jacobsen Chief 800 needs a good used clutch/starter/pto pulley (large pulley nearest the 8HP kohler engine)

 

As many know the Ford 80 ( and maybe 100 ) are almost identical. So, any part help or leads would be appreciated.

 

An existing crack finally went all the way on the original pulley

Wow. this sounds promising.  I can't see why they would have different dimensions, but not sure.

 

do you have basic dimensions available, or do you want mine ??  Thanks !

Interesting. As to removing, aside from a small
Lock screw, the pulley is not very tightly attached to the shaft.

Over time I think the lock screw applies enough pressure to cause a crack to form if the metal has any weakness. 40-50 years of tough work is not bad, however !

What is the pulley made of? If you cant find a replacement, and if it is a weldable metal, you could get your broken one welded, then drill the center and put a sleeve in it to fit the shaft without stressing the weld areas.

Obviously, replacement is better, but if you can't find one...

Or if you find a replacement with same pully dimensions but different size shaft - could bore or sleeve it to make it fit....
