I have a '01 MM that I'm having trouble removing the primary clutch on and could use some suggestions to help get it off. I've never had a primary this difficult to remove and prefer not to break something in the process... I'm using the removal tool that I used to remove the primary on my '02 Viper as I'm assuming the same tool works for both sleds? Any advise or suggestions that help me would be great.

One good and "soft" way is to:

-Turn sled on side.
-Fill bolt hole with water.
-Turn bolt (with same thread that puller has) in about 1/2 inc. You can use some tape on thread that there is no leak
- Leave it out and ice will pop it out !

I don't like to use hammer etc...
 
Careful with the torch as it can generate too much heat in a localized area which can lead to heat stress of the sheaves.

I use a little grease behind the puller which acts like a hydraulic pump when the puller is tightened with an impact wrench. I know the manual says not to use an impact wrench, but if used sensibly it will not damage anything. Make sure it is a good puller, or you could destroy it. Sometimes a little penetrating oil on the shaft helps too.

Heat with a torch? Won't that make heat cracks?
 
One more note . . .

Don't hit the puller with a hammer as that force is delivered directly to the crank bearings. The hammer action of an impact wrench is not in the same direction as hitting the puller with a hammer.
 
Thanks for all the replies! I had already tried the grease trick, but had no luck using a wrench so I did my reclutching work w/ the clutch still on the sled. I will try the grease trick w/ the impact wrench & hopefully it'll pop....... Maybe it's just me, but using heat on the clutch makes me think of gernades! :die:
 
mrviper gave me this little tip for the super stubborn clutches. the grease trick works for "most" stubborn units but, on the really stubborn ones.... pump the grease to the clutch so you can barely thread the puller on by hand, then tighten the puller and viola! POP!

disclaimer, some clutches that "heat sieze" on the crank may need to be cut off. usually this is from not tightening the clutch properly on install. then the clutch basicly welds itself to the crank.

i am also in the "dont hit the puller or clutch" camp, and no heat unless absolutley necessary. nothing good can come from either or. ski
 
On my SXR600 2 years ago,couldn't get the clutch off either.Used impact and nothing.Then got one of them gel bags,the ones you can put in freezer and then use to put into a cooler to keep things cold.Lay the pad all around the clutch inside between the sheaves for a bit.Took impact after 5 minutes and BINGO, it came off.
