hey guys i have just installed a os twin plate clutch in to 31 with an rb25 neo and running a rb20 silvertop gear box. i changed the thrust bearing for the right one and stuff, but once i bolted every thing up i tried putting the slave cylender on and the fork is way too far forward. like i can get one bolt in it but just not the other. The fork and everything is in right way so dont know what it could be, any ideas? ive tried releasing the nipple too.

thanks

It's simple. The clutch has a different throw than the last. The way to overcome this is to modify the slave cylinder rod length. Shorten the rod inside the slave. Take it out and hold the slave cylinder back from the gearbox lining the bolt holes up by eye and then have a look at how much of the rod you need to shorten so it sits comfortably in the fork, then cut it accordingly. Dont make it a tight fit tho, you dont want your fork with constant pressure on the thrust bearing all the time if you can help it.

Yeah i tried that already i cut the rod so it is pressing against the fork firmly but not too hard. Then i put the gearbox in gear and put the clutch in and tried spinning the back wheels when they were off the ground but they are locked....and obviously spin freely when in netrual.

i thought maybe i cut too much off so i tried putting spaces but its still not engaging.

Any ideas?

Maybe i just need the right casrrier?

    • Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL
    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
