Pitman arm and gearbox issue

1884 Views 40 Replies 12 Participants Last post by  CHOCK
I have a 1967 mustang v8 manual steering car. My dad bought it new in 1966 so it is an early model. I needed to replace my steering components since they were pretty worn out.

I bought a Lares 18702 which has a 1" sector shaft which is what my car had from the factory as my tag was smb-a. I bought a 1 inch sector shaft pitman arm using part number c7za-3590-a which according to stangersite that should be my part number.

Now my issue is that I cannot get the pitman arm to go over the sector shaft by more than maybe 20%. Did I miss something in my parts ordering? Has anyone else ran into something like this?

I had to remove the paint on the splines from my Chocko box to get the pitman arm fully seated.

Yes. It is torqued down but the nut is not up to the sector
If by that you mean you have applied specified torque but the nut is NOT up against the shoulder on the spline, that's good. It would not be possible to tighten properly if the nut hit the shoulder.

It is simple a non matter in a way. That pitman will not slide all the way up on the TAPERED splines. The Nut is nearly (60 thousands lets say) from being correct to the sector. Is your torque 100 pounds plus? I doubt it by looking.
What is your torque setting-??
Another way here--Torque to 125 pounds, remove the nut washer, try to remove the pitman. Tell us how long, by what method did you filially remove it. Will be interesting

No the nut will not even fully thread on to the bottom threaded section so nowhere near the shoulder

I thought the nut looked thick…..I need to double check mine.

All nuts are not created equal.
I have a “Lares” pinion nut that is extremely tight when put onto an original sector shaft, so much as to be unusable. A nut with a reduced pitch diameter will also affect the torque reading.
See if you can try an original Ford nut.
