I haven't kept up on Ski-doo technology since I had my 99 Summit-X 670. Prior to that I had a 95 670. Both had approx 5,000 miles without any engine issues. My 92 580(3?) never had any issues either. Great sleds. In 2005 I bought a 900 Mtn Cat and have been on Cat since then, buying a 10 M8 which I'm still riding with approx 4,200 trouble free miles. I never had to disassemble the engines on any of these sleds.
Looking to upgrade but undecided what brand to go with. I want something that is hopefully as durable and trouble-free as my previous sleds.
I believe in 2008, the Summit 800 crankshaft bearings required service around the 2,500 mile mark to repack with Petamo and Isoflex grease. I may be wrong, but I believe there were crank issues, esp for people who didn't perform this maintenance. Maybe no issues for ones who did, I don't know.
Looking at parts fiches, it looks like these greases are not listed for the 800 cranks from 2012-2017. Not sure if the cranks still required regular maintenance.
With the 850 engine in 2017, I see Petamo grease on the fiche.
Does this mean the new 850's require routine crankshaft regreasing to replace the Petamo grease?
