4. When you are certain you have correctly
determined the proper shim pack, remove crossbar
and apply blue Loctite retaining compound to
vertical shaft. When fit between shaft and crossbar
is tight, use Loctite sparingly. When fit is loose,
completely coat the shaft.
NOTE: Do not apply Loctite to vertical shaft when
installing a clamp type crossbar.
Figure 12
5. Install crossbar on vertical shaft and push keys into
keyway with screwdriver. Do not drive key in with a
hammer, as this could loosen vertical shaft
bearings. Clean crossbar bolt threads and apply a
few drops of red Loctite.
Install 1/4" thick washer and shim pack, selected in
step three, on bolt. Install bolt into vertical shaft and
torque to 300 lbs-ft.
With crossbar installed, recheck gearbox bearings
for excessive drag or presence of free play. If either
excessive drag or any free play is detected, repeat
step three.
Figure 13
6. When installing a clamp-type crossbar, install
clamp bolts and torque to 85 lbs-ft.
Install crossbar block lock over bolt head. Place a
socket over bolt and drive in lock until it is com-
pletely flat.
NOTE: If drive-in type crossbar bolt lock is not
available, the weld-on lock may be reused. Install
lock over bolt head and weld it to the crossbar with
a 1/2" long weld.
NOTICE
■ Attach welder ground directly to crossbar. Fail-
ure to do so can ruin gearbox bearings.
