Sounds like it would be a good idea to learn how to service and repair clutches. What would be the best manual for a beginner? Cat clutches of course.

its not rocket science just go to the dealer and get a puller.

Get the service manual for your sled. It walks you through step by step, shows pics, & diagrams. Other than that there is the "Aean's Clutch Tuning Manual/Handbook" (not 100% sure on spelling or wording).
