Description
Master Engine Rebuild Kit for 1996–2013 Polaris Ranger and Sportsman 500
The Polaris 500 master engine rebuild kit covers repairs that require replacement cylinder, crankshaft, piston, timing, sealing, and valve parts. The crankshaft arrives with its bearings already installed.
This Kit Includes
- Cylinder
- Crankshaft with Pre-Installed Bearings
- Timing Chain
- Water Pump Seal Kit
- Complete Gasket Kit
- Moly Coated Piston
- (2) Intake Valves
- (2) Exhaust Valves
Pre-Installed Crankshaft Bearings
REV6 supplies the crankshaft with its bearings installed. Therefore, the buyer does not need to press those supplied bearings onto the crankshaft.
However, this detail does not confirm every bearing used elsewhere in the engine. Inspect the remaining bearings and related parts before assembly.
Check the Engine Before Rebuilding
First, inspect the engine cases and cylinder head for damage. Next, verify piston-to-cylinder clearance and check the valve guides and seats. Also, inspect the timing guides and tensioner because this kit only lists the timing chain.
Polaris 500 Master Engine Rebuild Kit Versus Refresh
If the cylinder, crankshaft, and piston remain reusable, compare the Polaris Ranger and Sportsman 500 master engine refresh kit for 1996–2013 models. The refresh option supplies timing, sealing, piston-ring, and valve parts without the cylinder, crankshaft, or piston.
Installation and Engine Break-In
After assembly, follow the correct startup and break-in steps for the rebuilt engine. Vary engine speed, avoid heavy loads during the first operating period, and complete the required fluid checks. Review the REV6 engine break-in procedure guide before the first startup.
Rebuild Guidance, Warranty, and Financing
Before choosing a kit level, review the REV6 engine rebuild kit guide.
REV6 backs this kit with a 1-year parts warranty. In addition, financing options for REV6 engine kits may be available.
