Type 9 long shot

PostPost by: shynsy » Fri Jan 10, 2025 7:27 am

Hi Folks,
I am fitting a type 9 that has had its shifter position to fit into a +2. It's not a voigts modified box.
Anyhow it had has a longer V6 input shaft and therefore a spacer between the box and bellhousing. It is also has a Milton concentric clutch slave fitted.
My long shot is... does anyone have a similar set up and knows what spacers the slave needs to give the required the correct tolerance to the pressure plate fingers.

I've done a concentric cylinder installation (using a different gearbox). I would say there is no 'universal' spacer dimension as it will depend on the gearbox used, the thickness of the adaptor plate used, and the specific design of the concentric slave cylinder. So you need to measure the distance from the throwout bearing face to the operating interface (fingers) of the pressure plate and then fabricate a spacer (or spacers) that is that distance minus whatever the normal throw out bearing clearance should be (1-2mm?). Obviously it's nearly impossible to do this measurement with everything assembled, so one way is to install the bell housing and adapter plate and measure from the rear mounting face to the pressure plate, then measure from the gearbox to bell housing mounting face to the throwout bearing face (with the throwout bearing fully retracted, of course). Also obvious is that careful and thoughtful measurement is required here, so your old school ruler won't do.
