The grub screw is located in the rear rocker shaft support pedestal and
prevents the shaft from rotating. It also aligns the oil passage hole
through the pedestal to the shaft. If tightened fully it also locks the
front/rear shaft movement due to it's tapered end. When I tighten it fully
the rear rocker arm fully compresses the spring and the arm does not rotate
freely on the shaft. The engine is an 18GB.
Sorry for the lack of information.

What kind of a car? What "grub" screw?

Subject: Rocker rebuild
I am rebuilding the rocker arm assembly and have come across a problem.
When
I tighten the grub screw tight it binds the rear rocker arm. Is it
necessary
to fully tighten this screw or does the pressure of the springs keep it from
backing out? I suspect the hole in the shaft to receive the grub screw is
drilled too far to the rear of the shaft so there is insufficient clearance
for the rocker arm. A bit of wisdom from the group would be appreciated.
TIA
Bill
