HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


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 …

Spec clutch setup and master cylinders

Post  cfgioja on Fri May 13, 2011 3:59 pm

I have talked to Eric about my clutch issue here and was wondering if anyone else who installed a spec clutch has ran into a no pressure build up in the pedal situation. I am wondering if it has something to do with the spacer plate that I forgot to measure for and installed anyway.

I was just curious, I am in the process of pulling the trans to do a rear suspension swap and will slide the torque tube back in order to remove that spacer plate since I have not had a problem in the past with bleeding.

No matter how much a bleed the system, I get fluid to poor out of the bleeder valve, but my pedal never gets stiff once I re close the valve and pump the pedal.

I never had an issue before, so I was curious if the spacer is possibly causing a bottom out on the slave cylinder. Eric said I needed to measure something to see if it was needed but I forgot about that when installing the plate.

Here are a couple of threads about measuring for the shim, if you don't have one already.

I can't imagine reinstalling the TT and trans without checking your clutch release first. Unless you wanted the practice Very Happy

I tried my Spec stage 2 with and without the shim, and there was good slave pressure with both (using 7/8 M/C). i ended up going with no shim as the TO bearing was lightly resting on the PP fingers, and I was happy with the release. How are you bleeding it?

FWIW, I measured mine with and without the shim. The shim was needed as the documentation said it would be with the Stage one kit.

I would compress the pedal a few times, hold it there with a rod, reach into the bleeder and turn. I would get some fluid but nothing like I have before. this time it just seeped out. When I ran with out the shim it had enough pressure to squirt out.

Needless to say I am still running the stock MC. It might have an issue too but it didnt have any trouble building pressure 5 mins before I installed the shim.

Same setup here. The supplied shim was so thick that the TO bearing would run into the back of the clutch hub and keep it from releasing. Still, I had really good pressure and a firm pedal. You should upgrade the master while you're on it. I use one of these for bleeding and it's awesome: [You must be registered and logged in to see this link.]

I'm really happy with this clutch, BTW.

Has this method been tried?

The video is over 7 minutes...you can skip halfway ahead and start it at about 3-1/2 minutes.

I had a similar issue getting the clutch bled the 1st time - Stage I with the Wilwood MC and S-10 slave cyl, so a different setup from yours. Have you tried pulling fluid through with a mighty-vac? That was the solution to get enough pressure to get the bleed started. I'm running w/o shim btw. According to Spec look for 3/8" travel.

I have only about 200 miles plus 2 track days on my car. The slave cylinder is leaking I fear as I've had to add a bit of fluid. Eventually I'll need to pull the TT out and check it out.

did you have to run an adaptor or anything with the tilton? I was looking at the Willwood setups? didnt know if they were about the same.

Just looked up the tilton setups, what series is yours?

I'm using a the te 75 series (PN75-875-U). Yes, it needed an adapter as it was clocked wrong.

According to the two. Tilton is 3.2" from flange to outlet and wilwood is 5-9/16". Let me edit this. Wilwood has a co/pact version length is 3.3".

Can u post a pic of your tilton?

You have the bleeder hose at the 12 o'clock position? I used factory master and it gravity bled.. Make sure clutch rod isn't adjusted to tight so Clutch master piston is covering the fill hole.. Cheap grease gun hose for the bleeder hose. Might not be pretty but I haven't run anybody over so nobody but myself has seen it.

I was going to edit but same thing... the shim shouldn't stop you from having a pedal that feels good. It might not release the clutch or it might push it to far but all you want in the released position is come clearance between the pressure plate fingers and the release bearing.

Think it has something to do with my pedal adjustment, but I am upgrading masters too.

The Wilwood MC' output ports are clocked at 9:00 when modded to fit the 944 firewall. The 13/16" Wilwood MC is easier to install because the body diameter is smaller than the 7/8" and the nuts turn freely after you grind a couple mm's off the inwards MC mount holes for Firewall stud clearance... it's all been posted with pics and you can do the MC mod with a Dremel tool or file if you're bored....

See I am debating about just turning the master sideways and not having to worry about the adapter.

Does it cause any problems with your rod travel?

Collin, you might want to check the Tilton pushrod thread size/pitch to see if it matches the adapter I machined for the Wilwood...FYI
