House's ITB XE build and re-build
Busy day today.
Got myself up to Ben with the new slave and bearing to see what we could do with regard to spacing the slave off box.
With a lot of tea fuelled debate, we decided that making a spacer behind the slave wouldn't be as easy as first envisaged. So we went with this idea

I made the ring from a big bit of tube, tidied it up and parted it off on the lathe at 2.6mm
Laid in place

I pressed the bearing in and it's raised the slave retracted height to 46.5mm which means brand new clutch travel will be around 5mm which is perfect.
Next, shift cut has been troubling me!! Some background info.
The quaife box uses a potentiometer connected to the indicator to display gear position. My original intention was to simply piggy back the signal wire to the ECU and then as soon as the gear change barrel starts to move, the ECU would be programmed to cut the ignition.
Here in is the problem, if the barrel is moving then the box is already trying to change gear but power is still applied. The answer is to fit some form of load cell to the lever so that as soon as the lever is pulled the ECU cuts the ignition and by the time the barrel starts to move the load on the box has been reduced and we're in business.
Handily, quaife don't give any scope for a load cell on their lever, with the neutral interlock going up through the lever aswell so changing it isn't an option.
Some tea and thinking later........
One load cell, courtesy of James at Relenetless, I cannot speak highly enough of how helpful he has been.

Some measuring and a bit of turning on the lathe led to this

Then some sweating and measuring 5 times, I had to cut down the end of the gear level push rod

A bit more turning and some clever tapping, half of the middle spacer is tapped 1/4UNF the other half M8x1.25. Put together and tightened up

When all was said and done, you can't resist a bench test!! I grabbed a false neautral between 2/3 cos the lever was only held by a bolt in the vice, when the input shaft is spun and the lever pulled properly all gears work beautifully, I even setup and adjusted the neutral interlock, so that's all done ready when it's back in the car
