[Healeys] Big Healey Pinion Oil Seal

[Bob Spidell]

It's a 'normal' right-handed thread.  The torque is handled by the yoke and 
splines, the 'jesus' nut just secures the yoke to the pinion shaft.

The torque spec on the nut is 150ft-lbs, and there is probably a large split 
lockwasher behind it.  I don't think a typical impact wrench will do the job, 
you need a large breaker bar and possibly a length of pipe on the bar for 
leverage--aka a 'snipe'--and penetrating oil and heat might help.  Make sure the 
car is properly secured, then get your cousin Rolf to put everything he has into it.
