proper spread of the pressed steel support arm to insure
proper tension on the threads of the pivot after the bushings
have been installed.

FIGURE 9
Install the pivot so that it is central with the tool. Install
the spreader tool I-1860 so that the two ends of the tool
rest against the inner faces of the upper support arms
and the flange of the support arms fits in the slots machined
in the ends of the spreader tool. Turn the hexagon
portion of the spreader tool until the gauge rests
against outer surface of the arms. This will spread the
arms 1/16".
2. Just start the bushings on both ends of the pivot. Lubricate item
with a tapping compound such as lard oil which will allow the
bushings to cut their own threads in the support arm without
scoring. Install the upper support arm pivot centering gauge J -
1860 - 2. Thread the bushings into the support arm until the
head seats tighten to 110 foot pounds. Remove both tools.
