Core Engine Component – Precision-balanced complete crankshaft in OEM quality

Restore full engine output and smooth operation to your ATV or Side-by-Side! This Premium Complete Crankshaft Assembly is engineered to convert piston movement into smooth, continuous rotational torque. It serves as a direct replacement for engines affected by connecting rod failure, worn rod bearings, or damaged journals caused by oil starvation or high mileage.

Off-road utility riding puts severe stress on internal engine components. A factory-balanced crankshaft eliminates harmful vibrations, protects engine cases, and preserves main bearing longevity.

Installation & Maintenance Instructions: (For guidance purposes only)

• Visual Check: Prior to installation, perform a visual check. Match shaft journal dimensions, flywheel taper, drive gear tooth counts, and overall length against your original part.

• Complete Overhaul Recommended: Crankshaft replacement requires full engine crankcase disassembly. Always replace main bearings, oil seals, and crankcase gaskets during assembly.

• Pre-Lubrication Required: Coat all rod bearings and journal surfaces with clean engine oil or assembly grease before installing. Spin the engine without ignition to build oil pressure before initial startup.
