5 OPERATION & CONTROLS
NOTE: If the brass bushing is removed from shaft, apply
Loctite #290 or an equivalent to inside of bushing
before re–installation.
If the eccentric is removed from the shaft, Loctite
#290 or an equivalent, must be applied to the eccen-
tric surface and to the key on the shaft before re–

SPRING PRESSURE ADJUSTMENT

1. From left side of cut-off, install washers and spring on
tie rod and pressure plate assembly (replace brake
lining if needed). Check the length of the spring. The
length of the spring must be 4" + .050" (102 mm + 3
mm).
NOTE: If the spring length is not 4" + .050" (102 mm + 3
mm) the spring MUST be replaced. DO NOT add
washers or shims to make up the difference in the
length of the spring.
2. Install assembly into cut-off case housing and push
pressure plate (with tie rod) into shaft until the spring
and spacer(s) are inserted as far as possible.
3. Measure the distance from the housing flange to the
brake lining. This dimension should be 7/16" + 1/64"
(11.11 mm + .395 mm).
