Transmission Main Output Shaft for Buggy Kinroad 250GK (172MM Engine)

Maximum Torque Transfer & Heavy-Duty Off-Road Reliability! – Transmission Main Output Shaft for Buggy Kinroad 250GK (172MM Engine)

Heavy-Duty Transmission Replacement Part – Precision-machined secondary drive shaft in OEM quality

Restore solid drive power and smooth gear operation to your buggy! This Premium Transmission Output Shaft is engineered as a direct replacement for the Kinroad 250GK buggy and other vehicles powered by the popular 250cc liquid-cooled 172MM engine platform. As a crucial core component inside the gearbox, this shaft handles direct torque delivery to the drivetrain.

Rough off-road driving, heavy landings, and aggressive acceleration can cause gear teeth splines to chip, wear down, or shear completely. Manufactured from heat-treated alloy steel, this replacement output shaft offers extreme torsional strength and durability, preventing gear slippage and mechanical failures.

Installation & Maintenance Instructions: (For guidance purposes only)

• Visual Check: Before assembly, perform a visual check. Count the tooth configuration on all gear profiles, measure total shaft length, and verify bearing journal diameters against your original shaft.

• Clean Environment & Bearings: Gearbox repairs must be done in a dust-free environment. Always replace adjacent ball bearings, needle bearings, and oil seals when replacing a transmission shaft. Lubricate all gears thoroughly with clean gear oil during assembly and refill the gearbox to the recommended level before starting the engine.
