Crankshaft Bearing Kit by MOOSE OFFROAD HARD - PARTS (manufacturer's ref: 24-1023). This kit includes the left and right crankshaft bearings necessary for replacement during engine disassembly or crankshaft refurbishment on motocross machines.

• Contents: right and left crankshaft bearings (units: kit).
• 2-stroke: 2T kits also include outer seals, equipped with a fluorocarbon lip to reduce friction during dry starts.

Before installation, check the condition of the casing, bearings, and axial play of the crankshaft to ensure proper fitting.

Product intended for the replacement of original bearings to restore smooth rotation and good crankshaft behaviour after servicing.
