How far does a clutch friction plate travel?
I am building up a bellhousing/concentric clutch pack to match my rebuilt Type 9 gearbox to my new engine Rover T16 and am trying to work out how far
into the clutch cover/clutch plate the input shaft should go. I can vary the the thickness of the adaptor plate on the back of the bellhousing and/or
the concentric clutch carrier to suit.
Q1. - The input shaft splines are 43.3mm long and I am assuming that ideally the mid point on the friction plate centre should match the mid point on
the input shaft splines when it's all locked up (engaged), is this a good asssumption?
Q2. - When I release the clutch, the friction plate will come back from the flywheel, so that the clutch releases - how far does it travel? I'm
thinking maybe 2-3 mm?
I think that this question is one for those that have built their own bellhousing etc., I have been very impressed with the work on here, all
contributions gratefully received.
Thanks in advance.

What reall matters is the relation between the spigot bearing in the crank and the journal on the first motion shaft,
The splines on the first motion shaft are longer than they need to be, the driven plate only clears the the flywheel by about 0.5mm when the clutch
is pressed.
The hub of driven plate will also move about 2mm closer to the flywheel as the friction material wears.

Thanks britishtrident, that's good stuff.
The reason for all this because the standard T16 clutch cover is deeper than the old cover, so everything is positioned slightly differently to the
old engine/clutch pack.

Err No!
But just shows if you ask the wrong question, then you get the wrong answer most every time.
