FAQs
Does this CSC come with new seals?
Yes, as a complete hydraulic assembly, it includes the necessary seals and internal components for direct replacement.
Can I install this without removing the transmission?
No, the concentric slave cylinder is mounted inside the transmission bell housing and requires the transmission to be removed.
Is it necessary to replace the clutch master cylinder when installing a new CSC?
While not strictly required, it is highly recommended to replace both simultaneously to ensure consistent hydraulic pressure and prevent system contamination.
What type of hydraulic fluid should be used?
Always use the fluid type specified in your vehicle's owner manual (usually DOT 3 or DOT 4 brake fluid).
What is the weight of the unit?
The unit weighs 0.48 kg.
Troubleshooting
Spongy or low clutch pedal feel
There is likely air trapped in the hydraulic line; perform a thorough system bleed.
Leaking hydraulic fluid at the bell housing
Inspect the quick-connect seal and the internal O-rings; ensure the unit was not damaged during insertion.
Difficulty shifting gears
Verify that the clutch is fully disengaging; if the pedal is firm but shifting is stiff, check for air or master cylinder failure.
Pros and Cons
Pros
- Meets rigorous O.E. standards for reliability
- Precise 34 mm bore for consistent engagement
- Lightweight construction for ease of handling
- Quick-connect fittings simplify the installation process
Cons
- Requires professional hydraulic bleeding equipment
- Installation involves transmission removal on most vehicles
- Incorrect bleeding can lead to premature failure
Setup, Compatibility & Care
Proper installation is critical for the longevity of this component.
- Compatibility: Verify this part number (810019) against your specific vehicle make, model, and engine type, as hydraulic clutch systems are highly specific to drivetrain configurations.
- Installation: Always ensure the transmission input shaft is clean and free of debris before sliding the CSC into position. Use a light coating of high-temperature clutch grease on the shaft splines.
- Bleeding: Air trapped in the hydraulic line is the primary cause of 'soft' or 'spongy' pedal feel. Use a vacuum bleeder or a pressure bleeding kit to cycle fluid through the system until no air bubbles remain.
- Maintenance: Periodically check the clutch fluid reservoir level. If the fluid appears dark or contaminated, perform a system flush to prevent internal seal degradation.
