They are tight. I even tried heating one on a p60 and still broke the flywheelI would definitely recommend using heat on the pioneer flywheels. They seem to always be stuck on there really tight. I use a small plumbers torch on propane or MAPP and get it good and hot while there is tension on the puller, then give the puller a few whacks with a big hammer. Its that or alternate heat and penetrating oil for a few nights.
There are a few pioneer collectors in the GVRD if you need help.
