Hi
Lots of apologies for asking this (again!) but- I just wanted to make sure my info was exactly right before going any further and I know somebody has supplied some of this info before
If somebody out there has a handy 4 speed box could they confirm the following measurements (or challenge them)-
Distance from front face of box (without the bellhousing fitted) to start of splines- 100 mm
Spline length-43mm
Distance from end of splines ie nose end to end of shaft- 32mm
Plus (asking a lot I know) if somebody has a std 4 speed clutch friction disc could they measure the length of the splined section.
Many thanks
John

I have my 4-speed on the bench at the moment so I measured for you. I agree with the 43 and 32mm measurements however I get 85mm from front face of gearbox to the start of splines, compared to the 100mm you quoted.
The spline thickness of my clutch plate splined section I get 25mm.
Hope this helps you!

Further to your questions that appear on my phone but not on this thread on my PC
I can confirm that my 85mm measurement is from the flat face of the box to the start of the splines.
Depth of bellhousing is 173mm
Yes I am saying that the input shaft protudes 85+43+32=160mm from the flat face of the box.
Finally I get 54mm from the flat face of the engine (to which the bellhousing bolts) to the outer face of the flywheel. I hope that is what you are asking.
Unable to help more as I am away from home soon for a couple of weeks.
