Use the tape measure to find the
center of the axle and mark locaon
with a marker. For walking beam axles,
find a point about midway between
the pivot point of the equalizing
walking beam and the aachment
point of the axle. Please refer to the
corresponding Installaon Overview
for specific placement of sensors.
Place the Welding Jig Assembly
on the axle so that it is centered
over the line. Draw circles
around where the mounng
blocks will be located. Remove
from axle.
Use the angle grinder or sander
to clean the metal in the circles
to be welded. Make sure the
area is free of paint, dirt, rust,
and any other debris.
