Check the gearbox output shaft mounting has not sheared and bolts tight, and that the mounting does allow rotation of engine relative to chassis. Check you have stabiliser from top of clutch housing in place. Check clutch operating rod adjustment.
Check engine mountings are solid.

Sometimes the judder can be caused by a bent gearbox input shaft, if the gearbox has recently been off.

I would also check the tightness of the four gearbox nuts holding to clutch.


If not, replace clutch friction plate but also check clutch pressure plate that may have cracked.

In theory it could also be a loose flywheel, but unlikely and scary if it is.

If its a CA or CB Bradford its very important that the 3 clutch toggle levers are adjusted exactly the same which is to set to a clearance of 1/16'' between toggle lever and thrust race. Also that the ends of the toggle levers where they touch the thrust race or all ground to exactly the same angle.Also check that there is no sideways play in the thrust levers. It is also worth examining the thrust race which may be running dry or be knackered

If its a CC ts the same as any other borg & beck clutch so the above doesn't apply
