Steering torque

[Steve L.]

This doesn't seem to be in the AIM:
-Pitman arm to PS steering valve torque
-Steering box to frame- three bolts. I suspect these are the same as idler arm to frame at 70 lb-ft.

This is for a 73

Re: Steering torque

Greetings,
Unfortunately this reply is not going to directly answer the question. However, I tend to follow torque specs as closely as feasible myself, but I believe most "mechanics" laugh at those who would use them. Use common sense they would say; i. e., tighten enough to properly support the parts involved and so that it is unlikely they will work loose. Of course there are the so called "mechanics" who believe also that things need to be tightened to the point just short of fastener shear failure.....anything less is not sufficient. And while on the subject of fastener shear, how many of us have found someone else's work left with a fastener broken off, believing (apparently) that the idiot engineer was wrong in using three fasteners for a job when any high school graduate could see that only two, for instance, are needed.

Re: Steering torque

I just did the steering box installation using 80 ft-lbs of torque on the three bolts. This information came from an older version of the C3 corvette specs. I hope this helps.

Steve----

The pitman arm-to-control valve nut is torqued to 45 lb/ft plus the additional torque required to insert the cotter pin.

The steering gear-to-frame nuts/bolts are torqued to 30 lb/ft. These are 3/8-16 bolts/nuts. If you torque these to 70 lb/ft or greater you will likely way overtorque the bolts and, consequently, weaken or break them.

Steve -

The torque on that pitman arm-to-control valve stud nut is 43-47 ft-lbs.
