Description
Top End Rebuild Kit for 2003-2015 Ski-Doo Fan 550
Use the Ski-Doo Fan 550 piston kit when piston wear is present but both cylinders remain within their service limits. First, inspect and measure each cylinder bore before ordering.
What This Kit Includes
- Top End Gasket Kit
- (2) Moly Forged Pistons
Review the Kit Scope
This package does not list replacement cylinders or wrist pin needle bearings. Therefore, inspect those parts before beginning the rebuild.
Measure Both Cylinder Bores
Next, check each bore for scoring, taper, and out-of-round wear. Also, verify piston clearance and ring end gap before assembly. Do not install new pistons in cylinders outside their service limits.
Compare the Fan 550 Repair Options
If the pistons and cylinders remain reusable but the engine needs new sealing parts, compare the Ski-Doo Fan 550 Gasket and Seal Kit for 2003-2015 Models.
However, if you are comparing piston-only options, review the Ski-Doo Fan 550 Wiseco Piston for 2003-2015 Models. Confirm piston size and package contents before combining parts.
Assembly and Break-In
Before startup, check piston direction, gasket placement, oil, and bolt torque. Then follow the correct startup steps. Finally, complete the recommended break-in before long pulls or heavy engine load.
REV6 covers this kit with a 1-year parts warranty. If you need help confirming piston size or fitment, contact the REV6 team.
