Polaris Fan 550 Complete Top End Rebuild Kit 2002-2018

Description

Complete Top End Rebuild for 2002-2018 Polaris Fan 550

If worn or damaged cylinders have taken your Fan 550 beyond a standard top-end rebuild, this Complete Top End Rebuild Kit covers the larger repair. It is designed for 2002-2018 Polaris Fan 550 snowmobiles and includes replacement cylinders rather than requiring the originals to be reused.

What This Kit Includes

• (2) Cylinders
• (2) Wrist Pin Needle Bearings
• (2) Moly Forged Pistons
• (1) Top End Gasket Kit

Check What Caused the Cylinder Damage

Before installing the new top end, look for the reason the original pistons or cylinders failed. Check for signs of excessive heat, poor lubrication, intake problems, or other conditions that could damage the replacement components. Fix the underlying problem before reassembly.

Keep the Crankcase Clean

Protect the open crankcase while removing old gasket material and preparing the engine for assembly. Before installing the cylinders, confirm piston orientation, ring placement, clearances, and wrist pin bearing installation.

Can Your Existing Cylinders Be Reused?

If both cylinders measure within specification and show no damage that requires replacement, the Polaris Fan 550 Top End Rebuild Kit may be the better choice. It provides the piston-side rebuild components while allowing you to retain the existing cylinders.

If your repair extends beyond the top end, compare the Polaris Fan 550 Engine Rebuild Kit before deciding which rebuild level fits the job.
