If your original pin has become worn, damaged or lost, this genuine replacement helps restore reliable self-propelled performance and maintain correct drive system operation.
Titan Pro Tech Tip: Hub Alignment & Pin Inspection
The small self-propelled drive gears located behind your lawnmower's rear wheels are subject to rapid rotational shifts and sudden torque shocks during engagement. When fitting this 5mm x 21mm steel retaining pin, always slide off the wheel and clear away packed lawn thatch, old hardened grease, and dirt from the drive gear socket. Misaligned wheel hub assemblies or bent shafts can place shear stress on this retaining pin, leading to premature snapping or gear slippage. Inspect both sides of the drive system regularly for balanced power delivery.
Manufactured to the original specifications, this replacement retaining pin provides a precise fit and dependable long-lasting performance.
