ME630691 Mitsubishi BRG,CLUTCH RLSE FORK SHAFT, Price: 17.60$, Weight: 0.05kg

Clutch Fork Shaft Support Bearing ⚙️

This small but vital support keeps the clutch release fork shaft perfectly aligned inside the bellhousing. It reduces friction, holds the shaft true under pedal load, and prevents wear to the transmission case. The result is a smooth, light clutch pedal and clean disengagement for quick, quiet gear changes in manual gearboxes .

Why you need it ️

Without a healthy support bearing, the fork shaft wobbles. That misalignment stresses the fork, throwout bearing, and input shaft. An OEM-quality unit restores precise geometry and protects costly clutch parts, especially on Mitsubishi manual transmissions used for daily driving or towing.

How it works

Pressed into the bellhousing, the bearing or bushing acts as a low-friction guide. The shaft rides in its inner surface while you press the pedal. It carries radial load from the fork and keeps the throwout bearing centered on the pressure plate. A light film of high-temp grease ensures quiet, durable motion.

What happens if it fails ❗

Expect squeaks or grinding sounds, a notchy pedal, clutch drag, hard shifting, and accelerated wear of the fork and release bearing. Severe wear can seize the shaft, leaving the clutch stuck engaged or partly released, risking damage to the bellhousing and input shaft sleeve.

Symptoms and checks

Play at the fork, metallic dust near the shaft, off-center throwout bearing marks, and noise that changes when the pedal is pressed.

Replacement tips ️

Press the old unit out, clean the bore, and install squarely. Lubricate lightly with moly or high-temp grease, verify free fork travel, and inspect pivot ball and fork for wear. Best replaced during any clutch service for long-term reliability ✅.
