I recently picked up a 1974 5hp Briggs 130202 off an old tiller. Tank was pristine with no varnishing or dirt so things were looking good. The sheave on the PTO end was seized so I ended up cutting it right through the key way and wedging it off only to discover the shaft to be about one inch shorter than needed to accept a max torque clutch. I’ve been searching the internet for a replacement crankshaft with a 2-1/4” PTO. My question, is the journal size the same for both a plain bearing and a ball bearing application. Also is there a part number that has been superseded for a crankshaft with a 2-1/4” PTO shaft?
