Duratec clutch slave cylinder

[Elv15]

Hi Chris, the pull is in process. I'll post some pics as it progresses.

I'm compiling a list of parts (mostly gaskets) and other things to fix while I'm in there (small oil leak on the front cover of the engine), small weep on the tranny (don't know exactly where until I have the engine out - I recall Follis Jones had a nagging oil leak, I'll have to find his post about what he did to fix it).

Engine is out. The slave is blown. The clutch disk was quite worn for 20k miles. I suspect it was underated for the HP. There is burning marks on the flywheel and pressure plate.

I also disassembled the slave - it is not serviceable, but I was able to calculate the maximum travel - it has a maximum (safe) travel of 14mm. This will keep the piston in the bore. Any more travel and the piston is hyper extending and will evenutally pop out. Once it pops, it cuts the seal and it's toast.

I also measured the spacer in my transmission. It is 9.3mm. I need to build a tool to measure the TRB to pressure plate distance. This will tell me if the spacer is the right thickness.

I'll need a new slave and a new clutch (at the very least). I want to find a clutch that will not wear as fast but is still streetable. IMG_9175.jpgIMG_9177.jpg

Tom, what clutch do you have now? I'm using Raceline's AP Racing HD/lightweight flywheel combo which is every bit as drivable as my various tintops. No idea on the wear rate, but it is about 25k miles old with no indication that the end is nigh.

I also have a clutch from AP Racing in my car, but I do not know the part number/model number.

It has the stock flywheel (big brute of a thing). Not sure of the clutch disk. I'll take a pic of it when I get home...but it looks like a stock unit.
