72zcar Posted June 7, 2004 Share Posted June 7, 2004 info: 68 327, 89 t-5, after-market 16 pound flywheel, "special" disc with smaller spring so they don't hit flywheel bolts, camaro slave, camaro master. problem: Installed in car with fabed mount to hold camaro slave in right location to get full travel of piston in master. Does not work at all. Bled for days..still does not work. Took whole thing out of z..put on the bench with all lines connected it works good..push on master and slave moves at least 1 inch with no problem... but back in car moves only 1/8 inch. Hmmm: we think after all day of this may have figured it out...tell me if I am right........16# flywheel is thiner therefore allowing p-plate to be forward and of course then the t-out bearing is more forward making the fork pivot forward. Now the outside part of fork is already moved some..so the piston in slave is pushed out already. if buddy hold fork back with hand from under z when i step on pedal it gets pedal and pushes fork forward with force. Have any of you guys had this prob when using a light flywheel? would extending the slave rod fix prob? Am I insane? Quote Link to comment Share on other sites More sharing options...
JMortensen Posted June 7, 2004 Share Posted June 7, 2004 When you tested this out of the car the slave moved 1". It should also move 1" on the car. If it only moves 1/8" on the car, then the most likely culprit is air in the lines which doesn't compress when its on the bench but does when it has to push on the pp. Sounds like it still needs a good bleed to me. A longer rod won't make the piston in the slave travel any further. Could also be a leaky master or slave, but that should be pretty apparent especially out of the car...

72zcar Posted June 7, 2004 Author Share Posted June 7, 2004 re-read my post if u have time.. what i am saying is the slave is mostly already extended so it can not go much more. nothing leaks and we bled till we are pretty confident the is no air.

JMortensen Posted June 7, 2004 Share Posted June 7, 2004 OK, if the slave has to be 7/8" extended to hit the fork at all, I'd say you need a longer pin. Quote Link to comment Share on other sites More sharing options...
72zcar Posted June 7, 2004 Author Share Posted June 7, 2004 when the slave is installed and the pin is on the fork it can be pushed back into the slave about 3/4 to 7/8 of an inch before it bottoms out. why is this, its the same slave that came with the camaro type bell and tranny, the only thing that is not original is the flywheel. I did not measure it but from memory and by looking at the flywheel that came with the tranny i think it is thinner. I think this is what is causing the problem. If i get a longer pin it may work but the angle will change and the fork may even go full travel before the disc disengages.. Quote Link to comment Share on other sites More sharing options...
Dan Juday Posted June 7, 2004 Share Posted June 7, 2004 Sounds like you are on the right track extending the pivot. Can you post some pics of the Camero master installed? If it truly works you may be the first person to successfully pull this off. Quote Link to comment Share on other sites More sharing options...
72zcar Posted June 7, 2004 Author Share Posted June 7, 2004 Dan Juday I can post pics of the camaro master and bracket..but first I want to make it work..haha Quote Link to comment Share on other sites More sharing options...
mas8230 Posted June 12, 2004 Share Posted June 12, 2004 I had the same headaches with the slave and master. I even tried a pedal adjustment. I bled for hours, and after what seems like gallons of brake fliud, I still only got maybe 1/2" travel at the fork. I then took everything outan took the boot off the slave to watch piston travel. I was sure all air was out. After I watched piston travel, It looked like it wasn't moving as much as it should. I then took an old sbc oil pump drive shaft and made a new rod about 1/2" to 3/4" longer than the stock camaro rod. I installed it, and everything works great, FINALLY !

wheelman Posted June 12, 2004 Share Posted June 12, 2004 The other way you could solve this is by using an adjustable stud pivot ball for the clutch fork. They are about $15.00 through PAW (Performance Automotive Warehouse). Part number is LAK-15501. The one I bought allows you to adjust it from 1 5/16" to 1 11/16". I haven't received mine yet so I'm not sure it will eliminate all the 7/8" offset you're seeing but it will get rid of most of it, which means less pounding on the tranny tunnel to clear the clutch fork. Hope this helps Wheelman Quote Link to comment Share on other sites More sharing options...
Guest BillV Posted June 15, 2004 Share Posted June 15, 2004 If it is that the flywheel is thinner, there are bushings available that go between the crank and the flywheel to get it back to the correct position. These are sometimes needed if a flywheel is resurfaced more than once. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted June 15, 2004 Share Posted June 15, 2004 I think I'd rather put a longer pin in than put a bushing in between the crank and flywheel. That sounds like a bolt shear fiasco waiting to happen. Quote Link to comment Share on other sites More sharing options...
