Allis Chalmers 914 Mower, Lawn and Garden Tractor

Kohler K321 14HP

If you use the front shaft on your engine you will need to find out what size it is before buying anything. They are generally 1" diameter and there is nothing that will directly replace them. Parts from a K301 12hp and a K321 14hp Kohlerwill interchange except for the piston. You can replace a 12hp block with a 14hp block.
