Well. I consider myself very experienced and adept with the clutch cable assemblies on Mustangs, but as always there's always something new to learn. I post this because many of us have hard disengagement issues and I wanted to help bring this to attention. Recently after a cable replacement my clutch disengagement became more difficult as the rpm's increased. Higher RPM=NO DISENGAGEMENT. Traditionally I would think that the clutch must not be depressing entirely and I would simply adjust the cable tighter. Well, I chased the problem for 2 weeks, and realized yesterday in doing some online research that it is common to overload the assembly (cable, throwout fork/bearing and clutch fingers) with too much preload tension. Even if your tob doesn't seem to be riding the clutch fingers, you are still inhibiting the clutch fingers from performing properly when you depress them further than they are supposed to be depressed. Seems obvious, but I didn't think it was possible to overly depress the clutch fingers . Tomorrow I will back my cable off and readjust. If anyone has more info about this OVER CENTERING or OVER TRAVELING condition please chime in. Thanks.
