Set Clutch Parts BMW M5 M6 SMG III

This set includes all 8 piston seals for the selector rods located on top of the gearbox. The seals are made from a higher quality and more durable material than the original ones.

The pressure accumulator is responsible to store the pressure of the hydraulic system for later access by the actuators. This piston type accumulator has two cells: one cell storing the hydraulic fluid and one cell containing a Nitrogen gas filling which creates the counterpressure. Both cells are separated by a moving piston. Typical symptoms of a faulty pressure accumulator are frequent and short pump cycles. If there is no more preload pressure left in the accumulator, the pump runs every few seconds, which ultimately leads to a consequential damage of the pump motor. Along with the pump motor, a faulty pressure accumulator is one of the most common causes of pressure build-up issues and is one of the few wear parts in the system that should be regularly checked and replaced if necessary.

The replacement part we offer is a brand-new OE upgrade with improved internal piston seals, resulting in significantly increased durability.

These O-rings are designed for the four solenoid valves of the VANOS system in the BMW S85 engine. The solenoid valves regulate oil pressure for variable camshaft timing and are essential for proper engine operation. Worn or damaged seals can cause pressure loss, leading to incorrect valve operation and reduced VANOS performance. We supply new high-quality Viton seals to ensure reliable sealing and long service life.
