Frequently Asked Questions

Q: Do these bearings come pre-lubricated?
A: They feature a protective factory coating, but you should thoroughly lubricate both bearings and the fluorocarbon seals with clean 2-stroke engine oil or assembly lube before final crankcase assembly.

Q: Are crankshaft seals included in this kit?
A: Yes, this complete bottom-end kit includes both the left and right crankshaft bearings along with the matching outer oil seals.

Expert Pro-Tip: When installing new crank bearings and seals, always heat the engine case evenly using a heat gun and freeze the crankshaft beforehand to allow the bearings to drop in smoothly without hammering or side-loading the races. Ensure the fluorocarbon seal lips are lightly greased to prevent dry-start wear upon initial engine startup.
