Description

When a Yamaha Grizzly 660 engine shows wear across multiple systems, partial repairs often fall short. This master engine rebuild kit addresses the problem by replacing all critical internal components in a single, complete package.

Because the rotating assembly, top end, and sealing components are refreshed together, compression returns, oil control stabilizes, and long-term reliability improves. As a result, the engine is ready for years of hard use.

Every component in this kit is selected to work as a matched system and is backed by a 1-year REV6 parts warranty.

THIS KIT INCLUDES

• Intake valves
• Exhaust valves
• Cylinder
• Crankshaft
• Cam chain
• Complete gasket kit
• STD piston kit
• Water pump rebuild kit
• Oil seal set
• Crankshaft bearings
