You can call Spec-Ops and ask them to measure mine LOL. I'm in all day meetings today.

 

I think the key here is to measure like they tell you, I have a 2.3 and mine measured out fine with my forged crank.

 

I agree. However, there is nothing that you can do to solve this without machine work if you come across this problem. This isn't really an installer error that is causing this problem. It may have been preventable though. That's the point of this thread.

 

Correct. There is nothing to measure if the bearing doesnt clear the fingers. Their measurement is in case there is too much gap.

 

Yeah, their measurement states the minimum clearance as .130" If your clearance is .060"... you know you have a problem!

Their shims solve your problem if your clearance is .180" or so..

 

Also to note, once installed and used, the HRB will always tuch the clutch fingers, this is because nothing is going to return it all the way in to the assembly. This is normal, in this state there should be no tension though.

 

ughh.

i'm using a stock 88mm crank with a built 2L and oem mitsu thrust washers..

so typical dilemma. worry about this issue with the QM or worry about the retaining clip on an exedy triple.

was going to do a triple, then a QM 8 leg, now i'm torn on which way to go. dammmm nnn

 

THERE are solutions to both of those problems.

sorry for the typo...I promise I graduated from college

 

It seems it would be in Quater Masters best interests to investergate this and find a solution. If the tob is in correctly spec'ed it needs to be addressed.

 

The exedy solution is the push to pull and what's the qm solution? As I'm more interested in the qm personally?

The shimming? I thought qm said you didn't have to?

 

The quartermaster solution is to follow the directions. If you have excess clearance, shim it. If you dont have enough then get the throw out bearing machined down to get it in spec.

 

Thats how mine is.

 

Double or triple up the wave springs on the Exedy clutches.

 

knew that too, most likely thats what i'n going to do. convert my twin to a triple.

 

I'm not gonna say you're wrong, but I was told the release bearing shouldn't be turning all the time. It wasn't designed to spin thousands of rpms constantly. The bearing retracts after the master cylinder pressure is released because the fluid will try to reach an equilibrium. That would be the bearings natural state, which I would think is retracted.
