20524584 — Clutch Servo 4 Bolt 1672129 8171720 204394OEM

This is a clutch servo, a critical component in the clutch system that uses hydraulic pressure to actuate the clutch mechanism, enabling smoother gear changes. It is manufactured to meet stringent quality standards, ensuring reliable performance and durability compared to a worn unit exhibiting a spongy or unresponsive clutch pedal. Operator symptoms of a failing servo include difficulty engaging gears, a clutch pedal that feels excessively light or sticks, or a complete loss of clutch assist.

Installation & Application Notes

Always replace brakes in axle sets. Bed-in new brake pads with 8–10 moderate stops from 40 km/h. Check disc runout with a dial gauge — maximum 0.1 mm. Inspect caliper slides and pistons when replacing pads.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A gradual increase in clutch pedal effort or a spongy feel during operation is the first sign of servo wear. If ignored, the clutch may become increasingly difficult to disengage, leading to grinding gears or an inability to shift. Continued operation with a failing servo can put excessive strain on the transmission and clutch components.

Installation Tip

Ensure the clutch fluid reservoir is clean before opening the system to prevent contamination. Avoid overtightening banjo fittings, as this can damage the seals and cause leaks.

Service Note

Inspect the clutch master cylinder and clutch fluid for signs of contamination or leaks when replacing the clutch servo.
