Polaris Sportsman 570 Engine Rebuild (2014–2016)

Description

2014–2016 Polaris Sportsman 570 Engine Rebuild by REV6

Low compression, rod noise, and oil consumption can indicate internal wear in your Polaris Sportsman 570 engine. REV6 remanufactures your engine with inspected components, precision machining, and final assembly checks performed by our experienced engine technicians.

Our rebuild process addresses the crankshaft, cylinder, piston, cylinder head, timing components, and internal seals. Before purchasing, confirm the crankshaft and cylinder head configuration to ensure the correct fitment.

Important: Verify Your Crankshaft and Cylinder Head

Polaris used different engine configurations, so please verify these specifications before purchasing.

Crankshaft Identification

• Replaces OEM #: 2204729
• MAG end diameter: 22mm at the tapered end, just behind the flywheel threads

Cylinder Head Identification

The cylinder head must match one of the following OEM part numbers:
