[Tigers] Balancer bolt torque?

[Smit, Theo]

I think that the 220 ft-lb may apply for a 200,000 psi bolt being threaded
into a nut that is made from similar material, and where the load is being
spread over a suitably large area. Since it's going into nodular iron or cast
steel, and it's clamping something that may not be expecting to be crushed as
hard as applying 220 ft-lbs would, you're probably better off to use the
Ford-recommended 70-90 ft-lbs.

However, you should make sure that your torque wrench is reasonably accurate,
and that you use an appropriate fastener lube, to make sure that the 90 ft-lbs
isn't either 60 or 120.

Cheers,
Theo
