Allen,

There's no torque spec in the workshop  manual because one is supposed to a=
lign the dogs in the bolt head for a hand crank relative to #1 TDC, using s=
hims.  Probably doesn't apply in your case. If it was my engine I'd go abou=
t 120, which is between the recommended torque for 5/8 grade 5 UNC and UNF.

I don=92t see a torque value for the pulley hub to crankshaft in my Bentley=
 manual - TR3-4. I=92m going to help a friend in Austin do his timing chain=
 tensioner and so reviewing the manual and parts list. I did mine two years=
 ago but don=92t remember now what I did. It=92s a 5/8=94 bolt, so I think =
a torque similar to the head studs should be in the ball park. Plus there=
=92s also a lock plate with the fan mounting.
