Set Clutch Parts BMW M5 M6 SMG III

The internal gears of the hydraulic pump tend to wear mechanically and as a result the pump can no longer build up pressure. Our set includes new gears and metal seals that exactly match the original specifications and restore the function of the pump. In the process of overhauling the gear pump, we also recommend replacing the seals, which you can find here.

Our refurbished pressure accumulators are equipped with a filling valve and freshly filled with nitrogen gas.

The accumulator is responsible to store the pressure of the SMG system for later access by the actuators. The piston type accumulator has two cells: one cell storing the hydraulic fluid and one cell containing a gas to create counterpressure. Both cells are separated by a moving piston. A broken accumulator causes the pump to prime permanently.

Important: You will need to pay a core charge (deposit) of 300,00€ which will be refunded when you return your used part. You can learn more here. This is a repair service (no purchase of a product). Our terms and conditions and the right of withdrawal for the order of services apply.

New wiring harness to repair the gear position sensor strip located on top of the gearbox. Roughened or frayed cables are a common problem with this wiring harness. When the insulation of the cables is broken, short circuits occur, which lead to various SMG malfunctions and error messages (for example 4F80, 4F82, 4F85). Our wiring harness repair kit is supplied with a ready-made original BMW connector.
