NOTE: Omit step 2 when installing a clamp-type
crossbar.
IMPORTANT
■
Failure to accomplish step three as outlined
will result in an improperly shimmed crossbar and
gearbox bearing failure.
3.
Install crossbar on gearbox vertical shaft without
key in keyway. Make sure crossbar is seated firmly
against washer covering oil seal in gearbox neck.
Do not drive crossbar on vertical shaft. If crossbar
will not install easily, repeat step one until it will.
Select shim pack. Add shims until they are level
with shoulder in crossbar (point A).
The washer should only be used if using anti-wrap
washer.
Press shims in place very tightly and feel to see if
more shims are needed. When you reach the point
where adding one more shim will extend above
crossbar shoulder, do not add that shim.
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 shaft.
NOTE: Do not apply Loctite® to vertical shaft when
installing a clamp-type crossbar.
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 the presence of free play. If
either excessive drag or any free play is detected,
repeat step three.
