Oil Sump Gasket Kit for Can-Am Maverick X3 1000

The Can-Am Maverick X3 Oil Sump Gasket Kit includes the sump cover gasket and oil filler pipe O-rings commonly replaced during lower engine service on 2017-2023 models. Installing new sealing components during reassembly helps maintain proper oil sealing and reduces the chance of leaks after the repair is complete.

Whether you’re servicing the oil sump, completing a bottom-end repair, or replacing worn sealing components, installing fresh gaskets and O-rings helps protect your engine and supports long-term reliability.

Before You Begin Installation
