Removal
Remove the gearbox. Check for marks indicating the position of the clutch master part relative to the flywheel. If there are no marks, apply them yourself. Unscrew the 6 bolts securing the clutch master part to the flywheel one by one, using a screwdriver to block the flywheel ring gear. Remove the clutch master part from the guide pins (see Fig. 6.9).
Examination
Check the condition of the clutch drive disc. The wear marks on the ends of the pressure spring should be no more than 0.3 mm. Check the reliability of the spring connection between the clutch drive disc and the cover. No scratches or missing or damaged rivets are allowed. Check the clutch drive disc for cracks, burns and surface wear. Measure the thickness of the clutch disc linings. If their thickness is less than the permissible value, replace them or the clutch disc.
Installation
Before installing a new clutch drive disc, remove all protective grease. Thoroughly clean the splined portion of the gearbox input shaft and the internal splines of the driven disc, as well as the release bearing guide sleeve. Install the drive and driven discs on the flywheel and center them using a drift.
Caution: The flat side of the driven disc marked "flywheel side" must face the flywheel.
Tighten the clutch master disc mounting bolts so that the clutch disc is pressed down but still able to move sideways.
Using a drift or an old gearbox input shaft, center the clutch disc relative to the flywheel (see Fig. 6.11).
After centering the clutch disc, tighten the clutch drive bolts gradually and in a diagonal sequence to the specified torque.
Check that the gearbox input shaft splines, clutch disc splines and bearing guide sleeve are clean. Lubricate the gearbox input shaft splines and release bearing guide sleeve with a thin layer of FORD Special Grease #5021439.
Attention. The layer of lubricant must be thin and uniform, because otherwise, when the clutch is operating, excess lubricant will be thrown onto the working surfaces of the clutch, which may disrupt its operation.
Install the gearbox.
