Any one know if the crank length is different on a wd and a wd45?

Crank is identical other than the stroke. Will drop right in. You'll want the right pistons for it and using the 45 air cleaner and carb will help with air flow.

If you don't put a 45 manifold and carb on it,you're wasting you time. You can get by with WD air cleaner but 45 would be better.

What are the differences in the WD and 45 manifolds? Is it the opening size where carb attaches? Friend of mine has a WD carb on his tractor and it pulls real good. Could be some changes made that we dont see??

Regards,

Chris
