Master Engine Rebuild Kit for Can-Am Maverick X3 1000 (No Crankshaft)

If your crankshaft is still within factory specifications, this Can-Am Maverick X3 Master Engine Rebuild Kit provides the major components needed to complete a comprehensive 2017-2023 engine rebuild without purchasing another crankshaft. It combines pistons, connecting rods, valves, bearings, gaskets, seals, and timing components into one organized package.

Start by installing the complete gasket, seal, and O-ring set to help restore proper engine sealing during reassembly. Next, replace the cam chain and related sealing components to support accurate valve timing. Then, install the connecting rods, piston kits, and new bearings while rebuilding the bottom end.

After that, fit the new intake and exhaust valves as you refresh the cylinder head and valve train. Finally, complete the rebuild by replacing the remaining wear components included in the kit before verifying clearances and final assembly.
