Description

When a Yamaha Grizzly 660 engine starts losing compression or oil control, replacing only one component often leads to repeat failures. This complete engine rebuild kit solves that problem by refreshing the core internal components at the same time.

Because the rotating assembly and sealing system are addressed together, engine reliability improves while long-term durability is restored. As a result, your Grizzly is ready to get back to work or hit the trail with confidence.

Every component in this kit is selected to meet OEM specifications and is backed by a 1-year REV6 parts warranty.

THIS KIT INCLUDES

• Cylinder
• Crankshaft
• Cam chain
• Complete gasket kit
• STD piston kit
• Water pump rebuild kit
• Oil seal set
• Crankshaft bearing
