Little clutch issue help

[happy]

sorry up in Canada! I talked to a few people and it sounds like everything is working like it should and maby some of the slaves i changed were good..... it sounds like maby the fidnaza fly wheel or LUK clutch n pressure plate could be a different thickness maby closer to motor so the slave would be over extending and that might be the issue why i cant get a hard pedal. it sounds like my slave needs to move towards the clutch a little closer.. if that makes sense.

Good luck with it. I know there are lots of people using a Fidanza and Luk OEM clutch with no issues like you report. Myself included.

in the LS world t56, they recomend a shim behind the slave, it uses a HRB like the viper, just slightly shorter. https://www.tickperformance.com/tick...im-kit-3-pack/


How to determine if a shim is needed for your setup:

During each and every clutch install you perform on a newer GM vehicle, you must measure to see if a shim is necessary for proper installation. This is done by taking two simple measurements (see worksheet):

1) Measurement "A" is the distance between the surface of the bellhousing that meets the transmission to the tip of the pressure plate fingers. To get an accurate measurement, the clutch must be torqued properly.

2) Measurement "B" is the distance between the throwout bearing surface to the transmission surface that meets the bellhousing. To get an accurate measurement, the slave spring must be removed and the bearing must be fully seated at the bottom of it's travel; resting on the slave's base.

Once you've got your two measurements, make sure that measurement "B" is ~3/16" to 1/8" LESS than measurement "A". If you come up with more than 1/8", add an appropriately sized shim between the slave cylinder and the transmission in order to get the measurements where they need to be.

Your “A minus B” measurement should be 0.125 to 0.200 for adequate bearing travel and to allow for clutch wear. If there is no difference between the two measurements, or if "B" is greater than "A", there could be a problem with clutch engagement which could result in premature clutch slip and eventually a total failure. Contact your clutch manufacturer before proceeding with the install.

Here is a crazy idea we noticed yellow writing inside the bellhousing, looks like a junkyard bell housing.. if they happen to get one from a gen 3 viper would they fit on? maby its longer pulling the slave further apart? Or is that not even possible?

Have you bothered doing the measurements yet?

I predict he'll install [ ] two [ ] five [ ] eight more clutch slaves before measuring anything.

gen3 bell housing is different on the lower half. gen3 bolts to the oil pan, gen 2 has just a tin inspection cover that bolts on.

No I never measured anything my car is still in storage till later this month and no Dave I won’t be installing two five or eight more slave cylinders.... I’m a order a billet one from bbg allready talking to toddy! But will be measuring everything once I get it up on the hoist and get tranny out!

Thanks Ryan that scratches that idea of the list!

OK, I "presumed" when you said you found yellow writing in the Bellhousing that you had the car stripped down.

No I noticed it one of the times we had it out! Was justa crazy thought.. thought maby some one might have swapped it out once! Anyways once I get it out later this month I’ll get things hopefully straightened out! Thanks for the help!
