Ski-Doo Suggests using anti-seize Lube on the outer PTO Bearing...What works the best...Thanks Al.

ANTI-SEIZE!! My god no! Skidoo makes a special grease called iso-flex. Comes in a 50 gram tube and is good for 2 applications,cost $50.00!
There are two ways to put it on the bearing. 1- thru a special tube on top of the crank housing next to the clutch or, 2- tear the engine down and coat it buy hand. Not sure the older Mach's had the tube, if so, you will need a siringe to inject it in. I do this once a year to my 00 800 triple but just as a precautionary measure. Not to many MachZ's had a bearing problem but the 700's did.

Thanks Mikadoo...My 1994 Service Manual suggested Antiseize...I called the Ski-Doo Dealer and they told me to use the same product that you stated I really appreiciate you comments...I feel that Snowmobile World Net site is the greatest...I have the crankcase split now and will be doing the bearings by hand...thanks Al.
