auxilary Posted June 23, 2009 Share Posted June 23, 2009 too weak? I'm seeing everything on Tilton 7/8, I'm assuming that the stock Z clutch MC is too weak? Reason I'm asking is because tilton 7/8 + all lines/adapters come out to be $165. I have a pretty new clutch MC (Z is 5/8, if memory serves) for my Z already Quote Link to comment Share on other sites More sharing options...
pete280z Posted June 23, 2009 Share Posted June 23, 2009 I don't think the stock one will cut it. Another option is the GM master cylinder that LS1 Z mentions in this thread (post #20): http://forums.hybridz.org/showthread.php?t=100599 I opted to go with the tilton 7/8 but still have a brand new GM master like LS1 Z used. PM me if you're interested in it. You can have it on the cheap. Quote Link to comment Share on other sites More sharing options...
MONGO510 Posted June 24, 2009 Share Posted June 24, 2009 The reason for the change to a 7/8" cylinder is that the stock master is to small and will not move enough fluid to move the clutch slave, and disengage the clutch. John Quote Link to comment Share on other sites More sharing options...

winfab Posted July 1, 2009 Share Posted July 1, 2009 I used the Tilton and its mint. One word of advice though. Grab yourself a 5/16 x 24NF tap beforehand, because you will have to tap the factory clutch pedal clevis threads to this size. Grab a nut is the same thread as well, as these parts do not come with the new Tilton piece. Quote Link to comment Share on other sites More sharing options...
rwwisnesky Posted July 3, 2009 Share Posted July 3, 2009 If you use a Tilton, make sure you get the short one unless the washer bottle is not the same as the 280z. The long one would not clear the washer bottle so I had to get the shorter one. Also, if you take the push rod out of the Z master cylinder, you can swap it with the Tilton and will not have to tap the end on the peddle.

winfab Posted July 3, 2009 Share Posted July 3, 2009 The Tilton I used was the 75-875U. I kept the Tilton pushrod because i figured I would need more throw using the 7/8" rather than the stock MC, that's all. If i need to cut it down to size, then I can, but with the Datsun pushrod, you can't make it longer if the clutch on the LS1 won't disengage all the way.

auxilary Posted July 3, 2009 Author Share Posted July 3, 2009 that's the same unit i ordered. I think it replaced that 8754 one that was listed in another thread. or someone misread a 4 for a U Quote Link to comment Share on other sites More sharing options...
