So, just to set the scene, I have a completely brand new engine, brand new straight cut gearbox, with straight cut drops. (Rod change selector. Pre-verto clutch)
I have a pretty much new OBP pedal box with integrated master cylinders, with new slave cylinder, new clutch arm, new clutch plate, new clevis pins, new braided lines, etc.
The issue I'm having is getting it into gear when the engine is running. It's buttery smooth when not running though. I can get it to go into gear maybe 60% of the time, but it seems to stick a lot, like I have to force it, and sometimes it won't go at all. 2nd gear is the most stubborn.
In terms of adjustments, I have followed all the guides I can find on line. Set the arm 0.20mm off the stop bolt, press clutch in, wind lock nuts up to the clutch housing, release clutch, wind in an extra half flat, job done. But still the issue persists.
In terms of experiments, I have tried lengthening the rod that goes from the top of the arm into the slave cylinder, and I have tried adjusting my pedal to give more travel (something I am able to do with my pedal box), but it is STILL troublesome.
I'm pretty certain that in terms of hydraulics all is well, as it doesn't seem to make a difference how far I press the peadl in as long as it has engaged. The biting point is also relatively high and doesn't seem to change.
The only thing I can think of now is the gear selector itself. I'll admit that this is the one part I haven't refurbished, as up until my last engine came out, it was fine, but who knows. Could this produce the symptoms I'm describing?
Alternatively, is this just how straight cut boxes are? Will it get smoother as I put some miles on it and it gradually beds in?
Sorry to ramble, I just wanted to give as much detail as possible.
Any advice would be much appreciated!
Cheers
Chris
