semi circular thrust bearings that reside on both sides of the #4 main journal in the upper half of the block. function is to keep the crank from scraping the block as the crank moves longitudinally.

basically the crank moves back and forth slightly as part of normal operation. the thrust bearing takes the resulting wear. thrust bearings should last a long time, but in this case, improper pedal adjustment causes the bearing to sustain unnecessary loads.
 
oh okay

how should i adjust mine? i just make the arm under the dash 90 degrees from the master cylinder right?

well, the key would be to adjust the clutch so that it releases at the bottom of the pedal's travel instead of at the top. That way you're not moving the clutch fork any more than necessary to release the clutch.

The twin disc clutches seem to require less fork travel. More importantly, they have room for less travel. If the fork moves 2" and the pressure plate "bottoms out" at 1" of travel, there is 1" of unused fork travel. If you push the pedal all the way, the first 1" of travel is normal, after that, the pressure plate bottoms out. The hydraulic pressure goes way up, and this pressure pushes the entire clutch/flywheel/crank against the thrust bearing with extreme pressure. So you have to adjust your clutch pedal to limit the travel, or get a stop block.
 
well i just have an act 6puck with the xpp

i should be good right?
 
yeah ive seen that and hopefully ill be one of the lucky ones it doesnt happen to

Apparently part of the problem was that the ACT xtreme PP would bottom out if the pedal was adjusted too high. They re-designed it though. Just adjust your pedal pushrod so that the engagement is in the middle and you'll be good.
 
thanks raz


when it comes to nitty gritty stuff people cant remember verbatim you and doug are the go to guys
 
damm i was thinking of going with the twin disc clutch masters but now i dunno need more info on the stop block or pics... or maybe i should jus go with comp since ppl say there's no issue with them... dammit now im going be online for hours researching!

Mine's a competition clutch. The reason I went with CC was because people said there was no problems with it. They never seemed to say that you had to adjust the clutch. But I guess that adjusting the clutch is kinda common sense.

No matter what twin disk you get, if the engine seems to die or stall when you press the clutch pedal, you need to adjust the clutch.

There seems to be some people that just threw it on and it worked with no problems. But they have never said if they installed it or if they paid someone to do it. If they paid someone to do it, that person probably adjusted it and didn't mention anything to them because it's just simple maintance.

Or there's those that have a stop block on it. But nobody seems to have a pic of how it looks like or how to fabricate one or intall one.
 
Did anyone have to modify the factory throw out bearing when installing a Twin Disk?

I heard that is what you have to do with the B series one and its similiar to this one....
 
If for some reason the fangs for the clutch fork is not in the throw out bearing when installed and in the car, do I have to take out the transmission to put it back in?
 
i thopught the fangs are just supposed to be pushed by the TOB not actually cliped into it
