https://www.denniskirk.com/all-ball...t-bearing-and-seal-kit.p273224.prd/273224.sku (you said you have an 05 xc sp 500???) Here is the link to the All Balls Kit for either driveshaft or jackshaft. If you want to do both drive and jackshafts, order 2. They are the best bearings for the best price imo. Each kit includes chaincase and clutch side bearing, and chaincase seal. You should need about 12 oz. of chaincase fluid. To adjust the chain, loosen the nut on the tensioner bolt, finger tighten the bolt as tight as you can get it with your hands (NO TOOLS!) then loosen the bolt 1/4 turn (1-2 flats on a bolt head) and tighten the nut. For the track, with no weight on the track, you want 1" between the track and the slides 16" from the rear bogey wheels. OEM spec is slightly tighter, but the looser the track, the less vibration.
