Expert Installation Note: Critical Push Rod Alignment
Experience Tip: This unit is shipped as the master cylinder only. It is **CRITICAL** that you **re-use your existing push rod** to maintain the correct pedal height and travel for your specific **vehicle** or **equipment**. Improper push rod length can damage the seals or prevent the release of both the clutch and brake circuits.
⚠ CRITICAL: Verify Bore Size Before Purchasing
This unit replaces obsolete parts like FF48468 (**1 1/2″** Bore) and FF43812 (**1 3/4″** Bore). To ensure proper **vehicle** hydraulic function and avoid a mis-order, it is **absolutely critical** to verify your existing bore size is exactly **1 1/8″**. Using an incorrect bore size will lead to a dangerously inconsistent clutch or brake pedal feel.
Note: No repair kits are currently available for this master cylinder. This is a full replacement unit only.
