Description

625cc Big Bore Engine Rebuild Kit for the 2014-2017 Sportsman 570

This Polaris Sportsman 570 Big Bore Engine Rebuild Kit is built around the supplied 625cc cylinder and piston setup. It also extends beyond a top-end package with parts for the crankshaft, bearings, timing system, valves, and engine sealing.

As a result, buyers can cover several areas of the rebuild with one package. The exact supplied parts appear below.

This Kit Includes

• Upgraded crankshaft
• Heavy-duty upgraded big-bore piston kit
• New big-bore cylinder
• Main crankshaft bearings
• Complete gasket set
• Timing chain
• Oil seal kit
• (2) Exhaust valves
• (2) Intake valves

Crankshaft and Bearing Details

The crankshaft and main bearings are listed as separate components. A connecting rod is not included in the supplied parts list.

Because Polaris bearing selection can depend on engine markings, review the Polaris crankshaft bearing mapping guide. It explains how block and crank markings relate to bearing selection.

Big-Bore Piston Installation

Before assembly, check piston direction, ring placement, and cylinder preparation. Also, follow the required clearance and torque specifications for this engine.

For additional setup help, use the REV6 piston and ring installation guide. It covers several checks that matter during piston assembly.
