Crankcase Gasket Kit for Can-Am Maverick X3 1000

The Can-Am Maverick X3 Crankcase Gasket Kit includes the primary lower engine gaskets commonly replaced during crankcase service and bottom-end engine repairs on 2017-2023 models. Replacing these gaskets during reassembly helps restore proper sealing and reduces the chance of oil leaks after the engine is back together.

Whether you’re rebuilding the bottom end, replacing bearings, or servicing the rotating assembly, installing fresh crankcase gaskets helps ensure a dependable seal and eliminates the risk of reusing compressed or damaged gaskets.

Before You Begin Installation

Prepare the Crankcase Surfaces

Thoroughly clean all gasket surfaces and inspect the crankcase halves, cover sealing areas, and mating surfaces before assembly. Remove old gasket material completely and verify that the surfaces are flat and free of damage before installing new gaskets.
