Frequently Asked Questions

Why is fitment verification required for this Clutch Masters part?
The product depends on an engine, transmission, swap, or companion-part configuration that YMM alone cannot represent safely. Confirm every listed interface and the exact part number.

Should the flywheel be inspected or replaced with a new clutch?
Yes. Inspect the flywheel for heat damage, cracks, runout, and the correct step or friction surface. Resurface or replace it only according to the clutch and flywheel manufacturer’s specifications.

Is a clutch break-in period required?
Follow the current instructions for the exact clutch. Many street friction materials require controlled engagement cycles before full-torque use, while some race systems have different procedures.

Installation Instructions

Follow the current Clutch Masters and factory service instructions for this exact part number. Verify every interface before transmission removal, inspect and measure the flywheel and release system, replace worn seals and bearings, keep friction surfaces clean, use the specified fasteners and torque sequence, bleed hydraulic components, confirm release travel, and complete the required break-in procedure before full-torque use.
