QUESTION: YES CRANKSHAFT. WHEN TURNING CENTER BOLT PISTON TURNS WITH IT.NEW BELT WILL NOT GO OVER ASSEMBLY SPRINGS ARE ATTACHED TO ASSEMBLY. ITS A DIFFERENT SETUP FROM REGULAR LAWN MOWERS HOW CAN YOU REMOVE THE BRAKE BLADE CLUTCH ASSEMBLY WHEN SHAFT cable assembly is accessible but not belt

Answer
To replace the belt on most BBC models you have to remove the BBC from the crankshaft.

Check You Tube for "Craftsman blade brake clutch".  There may not be a video for your specific mower but there are several for Honda mowers...your's is very similar to the Honda BBCs.

Experience

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
