SRC 621 Help

Anyone familiar with the SRC 621 with the 6 speed setup. I'm replacing the Kawasaki engine with a Honda from another Cub Cadet mower. The drive pulley setup is a split pulley that is splined together with a bearing attached to the lower half of the pulley assembly. What has me puzzled is the drive pulley assembly has no key or any means of fixing it to the crankshaft. It appears to float on the crank??? Am I missing something??

Got my new parts in and figured out what the problem is. There is a small key milled into the pulley assembly that apparently broke off the old assembly. Makes sense now:biggrin:
