Gentlemen and assembled holders of knowledge;
I’ve a few questions about the steering box on my late 120.
At the bottom of the box is a large castellated nut which secures
the drop arm (pitman arm to us yanks) to the splined rocker shaft.
This nut cannot be removed while the box is installed in the car.
On my car, the drop arm (pitman arm) has some free play between the
nut and the shaft. This causes the drop arm to have a little bit of
up & down slop. I can see it move on it’s shaft. The steering box
is correctly adjusted and there is little to no play / slop in the
steering box. The play is at the bottom where the rocker shaft &
drop arm join. The drop arm end where it meets with the track rod
moves up & down as the drop arm moves on the shaft.
My question is: are there shims to be used to tighten up the drop
arm on the shaft? Is the drop arm / rocker shaft union a tapered
splined connection? If I, at great effort, loosen the nut on the
bottom of the rocker shaft, will I be able to tighten up the nut
and eliminate the slop in the drop arm / rocker shaft relationship?
Your advice & guidance are welcomed.
