Cranky Measuring Job

Anybody got their XK engine out, with the crankshaft still in it, and can give me an idea of height/distance from the bell-housing mounting flat back of the block to the back of the crank flange? A straight edge and a carpenter’s combo square would do the trick. I don’t think it makes much difference if a 3.8 or a 4.2, as I am trying to apply that dimension, at this juncture, to just roughly suss out the innards space of the bell-housing for a hydraulic release bearing and have some goodly adjustment in travel/height etc…via shims and different mounting & profile options.

Thanks much,

FYI, I just did this conversion on a 1935 Olds I restored. It too had a carbon ring setup. Not happy with the results. The carbon ring can take off-center misalignment. The steel race on whatever bearing you choose could chatter and wear on the clutch thrust plate at some points in it’s travel. Maybe someone has done this on a Jag and can correct me.

Good project,

Poor typing…that was 1 and 3/16th’s, not 13/16th’s

Super! Thanks much!! I will plug in the number and see if I am “in the realm”.

Thanks again!
