Hi, have just fitted some adjustable radius arm brackets and I am unable to find the settings in my trusty old Haynes manual.I did have a look, in the torque setting section but was unable to see it. In my Haynes manual all it has is the pivot shaft nut @53 lbs. Also how tight would you go on the sub frame mounting bolts ?

If there is no published torque wrench settings the the following is a good guide

1/4 UNC/UNF 7 ftlb
5/16 UNC/UNF 18 ftlb
3/8 UNC/UNF 30 ftlb
7/16 UNC/UNF 55 ftlb
1/2 UNC/UNF 66 ftlb
5/8 UNC/UNF 100 ftlb

and that's the thread size and not the size of the spanner you use

Thanks for that, no reason not to do it now. off I go maybe one more coffee

The old BL manual confirms that with 18 lb ft, and the new Rover manual with 25 Nm, which is almost exactly the same. It is a strange omission from Haynes.

By the way, that same torque figure is suitable for all 5/16" UNF nuts or bolts anywhere on the car unless otherwise stated. There are other figures for the UNC threads which screw into soft alloy in the transmission.

I set mine at 20 lb ft from an old bmc book I found
