Not wanting to put any undue pressure on the TOB I pulled the cable end as far forward as i could while pushing the clutch lever as far back and adjusted the cable with no free play. Tube is good, cable, pressure plate, flywheel etc all have about 30,000kms. Pedal stop is low and yet I have to push the pedal all the way to the floor to keep from grinding in 1st and reverse. I can not pull the pedal back at all as described in the factory manual. It works but barely- the travel is too far even with the cable adjusted with slight pressure on the shift fork lever.
It seems to me there should always be just the slightest play in the cable- no?? Any thoughts? Pete |

Pete Most flywheels have been machined at this point and it throws off the geometry of the clutch fork/cable setup. The fix is to install additional shims (washers) behind the clutch fork pivot ball on the trans (though this involves pulling the trans) or replace the flywheel (and still possibly re-shim the pivot fork) If you look at the clutch fork with the cable removed you will notice there is a gap on the forward side of the clutch fork between it and the trans housing, the larger this gap when installed in the car the worse this problem is. I cant remember the factory spec but I like to shim the pivot so this gap is as small as possible without touching. Anything over 1/4" and the clutch just feels like crap to me. When setup properly you can feel the clutch go "over center" about 1/3 of the way down in the pedal travel. Most 914s I have driven you can never feel it but its a night and day difference when setup properly. |
