Specs At A Glance

Good To Know

Q: How do I know if my coupler needs replacing? A: Common signs include vibration, loss of thrust, or visible wear and rounded splines where the coupler meets the driveshaft. Inspect it whenever the engine or pump is removed.

Q: Does this coupler require special tools to install? A: Installation generally follows the factory service procedure for the Xi Sport 750 driveline and may call for removing the engine or pump for access. Refer to your service manual for torque values and sequence.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
