Description
Valve Seal Kit for Can-Am Maverick X3 1000
The Can-Am Maverick X3 Valve Seal Kit includes twelve OEM-spec valve guide seals for 2017-2023 models. These seals help control the amount of oil that lubricates the valve stems while preventing excess oil from entering the combustion chamber.
Valve guide seals are inexpensive parts, yet they play an important role in engine performance. Replacing them whenever the cylinder heads are disassembled helps reduce oil consumption, minimize exhaust smoke, and support consistent engine performance after reassembly.
Before You Begin Installation
Inspect the Cylinder Heads
Inspect the valve guides, valve stems, valve seats, and springs before installing new valve guide seals. If the valve guides or valves show excessive wear, repair or replacement should be completed before final assembly.
