Core Functions

• Power Transmission: Efficiently transfers rotational force from the drive source to the oil pump (ensuring consistent oil pressure for engine lubrication) or differential motor (enabling differential operation for traction control), supporting the normal function of critical vehicle systems.
• Vibration Damping: Reduces vibration and noise during power transfer (via elastomeric components, if equipped), minimizing wear on the oil pump/differential motor and extending their service life, while improving driving comfort.
• Misalignment Compensation: Accommodates minor axial or radial misalignment between the drive source and the oil pump/differential motor, preventing binding or excessive stress on connected components that could lead to premature failure.

Compatible Vehicles

This Oil Pump Coupling (OE: 31256757) is tailored for the following Volvo models and year ranges:

Notes: This coupling is system-specific (oil pump vs. differential motor) and may differ in design or mounting specifications even for the same model—confirm the exact application (which component it connects to) via your vehicle’s VIN (Vehicle Identification Number) or Volvo’s official parts catalog to avoid fitment issues. During installation, ensure proper torque when tightening mounting bolts (follow Volvo’s recommended torque values) to prevent slippage or component damage. Inspect the coupling regularly for signs of wear (e.g., cracks, excessive play, or elastomer deterioration) and replace it immediately if damage is found, as a faulty coupling can cause oil pump failure (leading to engine damage) or differential motor malfunction (affecting traction control). Avoid using aftermarket couplings that do not meet OE standards, as they may not withstand operational loads and pose safety risks.
