The surface of organic clutch disc has worn off totally. The flywheel has worn irregularly, maybe 2 mm pits on it's surface. Whole lot of smut on the other side too, could slow down engine spinning at least on starting.Ĭlutch adjusting bolt's heads have worn off and partly locking nuts too. The front part and the other of two oakwood shocks, that make front axle stiff. This could also lock up starter's gear wheel, that didn't always move to the teeth of the flywheel ring gear when started. The gap between flywheel and gearbox casting is halfway full of black grime and smut, made of dust and oil.

The MF tool number for this is Tool MF220 (lever fulcrum height setting gauge). You need to set the clutch release levers to a height of 2.65 inches to 2.72 inches (67.31mm – 69.10mm) meaured from the face of the spacer ring segments. The setting is important and needs to be accurate.
Mention setting the spacers, so any advice would be much appreciated. This seems to be quite a shady area as none of the manuals don’t seem to Is there any easy way of setting these and how accurate does the fingerĭistance to the flywheel face need to be compared to what is stated in the
Stage of putting on the dual clutch, but am having problems working out the correct spacers required to set the finger distances from the flywheel face and to the spacer ring segments.
