For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Clutch measurement still wrong

Post by jpkinerk on Tue Aug 02, 2016 8:41 pm

So I've done some searching and addressed all the potential issues so far, but I'll recap here...

Installing a Spec stage II clutch kit w/ their flywheel, bleeder and slave cylinder. My "B" measurement (from slave cylinder to torque tube adapter), is more than my "A" measurement (from clutch fingers to bellhousing). The best I could get is B > A by .05 inches.

Things I've double checked:
- pilot bearing is seated properly
- pressure plate is torqued to spec
- removed spring from slave cylinder
- torqued down slave cylinder
- slave is properly compressed for measurement
- back side of slave has been notched to fit around torque tube adapter plate bolts
(this one annoyed me. I kinda thought it would come this way, however, I guess not all people use TPC adapter plates on their swap)
- adapter plate bolts are not portruding past engine facing side adapter plate

I've read some materials that say a little pre-load is OK, and others like Spec's instructions saying it's not OK. So what am I missing here?

Also, here is the post I researched from this forum. Same exact problem, but my pilot bearing is properly seated and not interfering with anything.

my only guess is something is machined wrong.

sort of a last resort, but you may want to try a slave from a 2005-2012 mustang. they bolt up the same as a gm slave and their compressed height is shorter than the gm slave.

one of these will give you another 1/8"

I bought one of these for my car but never ended up using it because my throw out bearing wasnt pushed back all the way... Are you sure yours is?

Spence, you nailed it. I THOUGHT i had properly compressed the slave, but apparently sometimes you have to crack the bleeder and even (carefully) compress it in a vice to get it down all the way. David at SPEC provided excellent customer service and gave me that idea today. The extra compression gave me an addition - 1/8" which is exactly what I needed. Here are some before and after pics.
