the C6C17WB2K is a 3/4HP washdown single phase motor in the same NEMA 56 
frame, so it should swap out with no problem.  You'd want to check to 
make sure the shaft configuration, etc. is the same.  (i.e. is a 1J the 
1/2 HP and the 2K the 3/4 HP, otherwise identical, or should you be 
getting a 1K or a 2J...  the leeson catalog would tell all)

Cat #112432 vs 112431


You'd also want to check the electrical ratings on the controller 
(Locked Rotor or start current, for instance..)

Full load for the 3/4 HP is about 11 Amps, 9 Amps for the 1/2HP
