Randall:
This kind of camaraderie and professionalism 'above and beyond the call of
TR duty' is what makes this list and our afflictions so enjoyable & most
wonderful!
There is nothing worse than starting a 'task' and finding out mid-way
through that one has 'overlooked' or 'not thought of' some technical aspect
which is critical to the success of the 'operation. I know now that I can
continue to enjoy the TR, and when weather permits the 'operation' having
thanks to you and others obtained the parts I need in advance- it will be a
pure joy- and my success will also be the success of ALL those who have
contributed to the 'event', in this case Greg, Carl S.,Brian, Michael, Steve
N., Sumner, and yourself!
Thanks and TRIUMPHANT Triumph-ing!

Subject: RE: Operation: TR4 Crank Bolt/Elec.Fan MOD / Our Technical
minds need to know!
I examined two original cranks, one from a mid TR3A, the other from an early
TR4. The hole in the front is very close to 1.5 inches deep, the threads
extend into it roughly 1.25 inches. The threads are 5/8-18 UNF.
If you are removing the fan extension, and using just a flat washer and lock
washer to clamp the hub into place, a 1.25" bolt should work fine. I found
that the flat washer would not clamp the hub tightly enough (it hits the
crank nose), so had to make a clamp piece that wound up being roughly 1/4"
thick, and switched to a 1.5" bolt. Adding shims between the hub and timing
chain sprocket might be another way to solve the problem, but I didn't think
of it at the time.
