My KEP 240mm Stage 1 pressure plate is not releasing and I've checked all the obvious things like a broken spot weld on the Boden tube (firewall & attachment by shifter), pedal box bushings, clevis, clutch cable,...etc. All the these items are great. I watched the Boden tube while actuating the clutch and it is still. The clutch won't release enough to allow gear selection while the engine is running. With the engine off, I can select all gears no problem (brand new gearbox). The car ran well and the clutch seemed to function properly for about 200 miles...then it quit releasing all the way...and found myself double clutching & matching revs to get it home. I then tightened the cable thinking it must have stretched under the strain of the KEP pressure plate..and it still won't release. I then used the "cave man" approach to determine whether the pressure plate will release manually or not. I disconnected the clutch cable @ the trans and slid a long pipe over the lever arm and cranked it over to it's maximum travel...had a friend hold it there while I got in the car (up on stands)...I fired it up and checked to see if it was released entirely and it was. It shifted into all gears properly with engine running. My question is...WHY can't I get enough clutch cable travel to actuate the pressure plate entirely...when it WAS working flawlessly for 200+ miles??? I'm starting to think that there may be something wrong in the disc, or pressure plate broken or cracked diaphram, or maybe the pilot bearing has failed causing the main shaft to spin with the engine? I won't be sure until I take everything apart and inspect these parts. Can anyone think of any thing else I may be overlooking?
Thanks,
Bill
