Hello again. After my rear crank oil seal went the way of the knacker's yard, I've needed to replace my clutch. I have an M40 4 speed non overdrive which according to my pitman's book of doom has a hydraulic diaphragm clutch thing. I gave my details to Brandon Auto Parts who sent me a Sachs clutch. According to the manual, a special tool is needed to remove the diaphragm clutch which isn't available to my friend or myself. If I've been given the later cable operated clutch, is it a straight swap? Can the diaphragm clutch be taken out (and possibly destroyed if it has to be removed by force?)

Argh right, Sorry I meant coil spring rather than diaphragm type. The concern really was over the clutch arms. I've recently spoken to Tony Barrett and was assured that they are interchangeable despite the different arm designs.

I have successfully removed the diaphragm clutch without any special tool, and indeed without suspecting that one might need such a thing...
