Complete Top End Rebuild for 2012-2015 Polaris RMK 600 CFI

- (2) Cylinders
- (2) Wrist Pin Needle Bearings
- (2) Moly-Coated Pistons
- (1) Top End Gasket Kit
Find the Cause of Cylinder Damage
Before putting the fresh top end together, determine why the original cylinders or pistons failed. Check the fuel and oil delivery systems, intake tract, cooling system, and related engine components for anything that could have contributed to excessive heat, poor lubrication, or cylinder damage.
Take Time With Final Assembly
Confirm piston orientation and ring position before lowering the cylinders into place. Check the required clearances and ring end gap as well. Finally, make sure the gasket surfaces are clean and ready for assembly before installing the new top-end gaskets.
Which RMK 600 Top End Kit Do You Need?
If both of your existing cylinders remain within specification, the Polaris RMK 600 CFI Top End Rebuild Kit may give you the rebuild coverage you need without purchasing replacement cylinders.
Only replacing one piston? The Polaris RMK 600 CFI Standard Piston Kit provides a smaller repair option when the cylinder condition and measurements allow it.
