Replacing the clutch release fork
The clutch release fork can be replaced without dismantling the clutch housing. Unscrew the two bolts securing the clutch slave cylinder and move it to the side. Remove the rubber boot of the fork and take it out. File the ends of the new fork on a grinder or a file along a plane like a wedge (see fig.). Illuminating the release bearing with a lamp through the hatch, put the fork in place, placing its ends under the spring on the release bearing using a hook. Install the boot, clutch cylinder and adjust the free play of the fork (4–5 mm).
