Small Engines (Lawn Mowers, etc.)/Cub Cadet 1215 PTO clutch stuck on shaft


I have a 1987 Cub Cadet model 1215 with a 12hp Briggs and Stratton. The engine has broken a rod and I'm trying to remove it to replace it, but the pto on bottom is stuck on the crankshaft. Can I use a puller to take it off or will it damage the pto? I have sprayed WD-40 on the top and bottom of pto to hopefully get in the crankshaft and loosen it, if it doesn't how can I safely remove it? All help is greatly appreciated.

Thank you,

ANSWER: You could damage it with a puller.  Is there a threaded hole in the center of the PTO hub?  Hard to tell from the parts diagram if there is a threaded hole or not.

Did you search online for a service manual?

QUESTION: If you are talking about the center of the hub being where the crank comes through it, that doesn't have threads. Center of the crank does, but not the pto. I did get it off, it looks like the WD-40 did the trick. I used a thin blade screwdriver and tapped it in between the pto and belt pulley and it loosened and came off. I appreciate your help.

Thanks for the follow-up and the tip.  FYI, some of the clutches have threaded center hole and use just use a long bolt to pull/push the clutch off...but you have to be careful not to damage the threads in the crankshaft.

Are you replacing the whole engine, short block or re-building?

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.
