Does anybody have any experience of choosing, fitting and using a modern clutch in a Triple-M engine? Any comments would be much appreciated.

Speak to the "Old Man" - he has done quite a few.
The difficulty is getting the pedal pressure and pedal feel - he used a variety of clutches depending on duty.
The most extreme being in the Amilcar Riley and Bolster Specials.
Barry Foster fitted a modern clutch to the C type a few years ago and ended up fitting a hydraulic slave cylinder too (not sure why).
I personally would avoid the competition type paddle clutches for anything other than racing - these are a bit sudden.

| John, I have fitted a Ford Laser (Escort?) flywheel and clutch to my F-type, principally because the original items had been extensively modified and were effectively beyond repair. It was not really difficult, but any flywheel you use has to have a fairly deep dish so that the friction plate does not touch the mounting bolts. Apart from Simca Aronde I do not know of any "modern" friction plate that is anywhere near one inch-6 spline so I had to weld a suitable female spline (found in the transmission of prewars and T-types) into a Fiat 125 component as I recall. It was also necessary to make a new thrust bearing holder (with a longer throw owing to the more shallow diaphragm type pressure plate) but mine had had it anyway. Pedal tavel is identical to the original system and the clutch operation is absolutely superb. I welded mounting lugs on to the ring gear to bolt onto the flywheel. |

For the past 12 years I have been running a Baynton Jones custom light flywheel and Ford diaphram cultch arrangement in my J type. I have also recently received another similar unit from Barry Foster for another J4 style project underway as this unit is in my opinion very good.
Admittedly, the clutch action is short and sudden, can feel heavy on the left foot in stop start traffic but other than that, it is easy to master and I would certainly recommend it.

Can someone please give a few more details on how a modern clutch can be fitted. On the M and J engines the boss of the crank rear bearing / flange protudes about 2" from the flywheel, towards the rear of the car. This is surrounded by the aluminium casting which takes the pressure springs and the inner friction lining. The depth of this casting and springs places the lining slightly further to the rear, than the rear of the flange boss, so the solid spinner plate doesn't foul. Surely to fit a modern clutch the flywheel will have to be fitted at the rear end of the flange boss to provide a flat surface for the friction plate. Will this not require a new flange to be machined to place the modern flywheel more to the rear ?

Best to start with a new flywheel designed for the modern clutch
