Hi Andrew, yes they are the same principal and also the clutch in the Stuart.
Getting into a bit of nitty gritty with the adapter plate and obviously they need to line up with little to no deviation.

[colin jones]

Fortunately the main pieces are round which does make it a lot easier making blanks. I turned up a bearing and hole plug to align the bell housing and the trans box which in theory should be a fool proof method and from what I have measured, it is good to go.

Everything is drilled and tapped and fits together nicely. I have to say that when I laid it over I found out "ITS BLOODY HEAVY" and I haven't got the gears or accessories in it yet. The poor old tank might have a permanent list to starboard.

Colin.

As a potential driver of these vehicles are you suggesting you may have to start packing on a few more stone?

Same, too, as many motorcycle clutches. I suppose driving a chain by sprocket and a track by sprocket are similar tasks, so I wonder which concept came first?

The multi disc clutch pack is found everywhere, and apart from hydraulic systems is universal in heavy machinery. (I can't think of anything else)

[David Herbert]

..And as clutches in all automatic gearboxes, machine tools, crawler tractors, and as oil immersed brakes in earthmoving plant axles. They were used as oil immersed clutches in WW1 FWD model B trucks too.

Silly question, but does the Chev engine turn the right way to ensure you have 4 forward and one reverse gear instead of the other way around?

[colin jones]

Bruce that's a very serious question that I have no idea about. I would have thought they'd just be the same but it is something that never even entered my mind. Perhaps the knowledge dept here can answer that one

[Lynn Eades]

Colin have you got crank handle dogs on both engines?
Most engines run clockwise as you look at the front pulley.
So if your V.L.T. crank has / had a crank handle and the dog is also the bolt that locates the front pulley and it is a r.h. thread, then your rotation will be the same for both engines.

I remember when Hyundai (I think) entered touring car racing. They had to use the same front wheel drive/gearbox system as everyone else, and it was only when their newly-developed 2.0 litre race engine was fitted to their brand spankin' new race car that they discovered.... you guessed it.
Bruce - not a silly question at all. Potential to save a lot of heart ache.

During WW2, when Rolls Royce car engineers were working on adapting the Merlin aero engine to use in tanks, they had change the rotation to Clockwise because that is how auto engines were and this entailed making new camshafts. This is not a myth, it came from the RR Historical book on the development of Meteor.
Just looked at the Light Tanks manual and the valve timing diagram for the Meadows (and Rolls on earlier Marks), appear to be clockwise.
