Servicing both 2013 800 quad clutch. Called dealer in Edmonton enquiring about bearings. I removed two sealed bearings from each one way clutch. Dealer tried to sell me bearings with one seal. I asked about grease and was told that no grease is necessary. Buying bearings, sealed for $42 a piece, was offered Chinese bearings for $17 (lol pass)and Mobil 28 as the all round grease, clutch, drive shaft coupling and chassis.
