Figure 6. Crossbar Puller
To remove crossbar with hydraulic jack, install the cle-
vis (1) using the blade pin spacers, keyhole plates and
bolts to each end of crossbar. Position square tube (5)
with threaded nut portion down.
Attach square tube to the clevises using crossbar puller
links (7) to space it away from crossbar. Place hydrau-
lic jack on square tube so end of jack presses against
end of gearbox shaft. Slowly apply force with hydraulic
jack.
NOTE: Hydraulic jack will not operate if tipped more
than 90°. It may be necessary to apply heat to break
Loctite bond on crossbar. Use caution to prevent bend-
ing crossbar when using either removal method.
Installation
The anti-wrap washer (2) was added as an inline pro-
duction change. Your cutter may not be equipped with
the anti-wrap washer (2). It is designed to minimize for-
eign material wrapping around the gear shaft and caus-
ing seal damage. You may order an anti-wrap kit for
installation on your cutter.
Select the 1-5/8" ID x 2-5/16" OD x 7 GA washer (1)
from the shim pack and install as shown. Install the
anti-wrap washer (2) next to the 7 GA washer as
shown.

Shimming
A properly shimmed crossbar is essential to obtain
good gearbox bearing life. Make sure the gearbox ver-
tical shaft bearing adjustment is correct. Bearings
should be just tight enough to remove all free play. You
should feel a slight drag caused by the seals, but not
enough drag to indicate pre-loaded bearings.
