Fitment & Technical Details
Thoroughly clean all mating surfaces, removing any residual sealant or gasket material without scoring the aluminum flanges. Inspect all bearing bores and oil seal channels before pressing in new components. Assemble the crankcase halves using an approved crankcase sealant and cross-torque all case bolts progressively to factory specification.Verification: Crankcase halves mate completely flush with zero gaps or misalignment, allowing the crankshaft and transmission shafts to spin freely with zero binding or axial play.
