[Spits] Timing chain cover nut

[Gosling, Richard]

OKCSpitfire - sounds like you are getting a little frustrated!  I'll
avoid the temptation to get into a slanging match on the relative faults
of British and American cars ;-)  I have no idea why Triumph chose such
a random size for their pulley nut.

One method for loosening the nut is to remove a spark plug, and feed a
lenth of rope into the cylinder.  This jams the piston, and prevents the
crank from turning, so you can then turn the nut, preferably with a VERY
long extension bar!

Another (more brutal) method is to fit the socket and an extension bar
onto the nut, then hit the starter motor.

Having said all this, shortly after I had a (professionally)
reconditioned engine fitted to my Spit, I remember noticing the crank
nut was loose, so I returned to the shop that fitted it.  They had a
nightmare trying to shift the nut, it wouldn't move either way, tighten
or loosen.  I can't remember what sorted it in the end, but I think it
involved a lot of brute force.


Richard
