13. Slide input seal (4) onto input shaft (5) and press
into housing flush with front using a tube of correct
diameter. Be careful not to damage seal lip.
14. Check gearbox housing for leaks by plugging all
holes except one. Apply 4 psi compressed air and
immerse the gearbox in water to verify that there
are no leaks.
15. Remove gearbox from water and dry off with
compressed air. Add SAE 80W or 90W EP oil until
it runs out of side level hole. Tighten all plugs.
CROSSBAR REMOVAL
1. It is necessary to gain access to bottom side of
cutter for crossbar removal. See Blocking Method,
page 16.
NOTE: You will need to use either the puller screw
(Item 6, Figure 15) or a small hydraulic jack to
remove the crossbar.
2. To make crossbar removal easier, remove blades.
See Figure 14.
Figure 14. Blade Removal
3.
Refer to Figure 15.
Remove retaining wire from
bottom of crossbar and remove nut and washer.
4. Attach a clevis (1) to each end of crossbar, using
blade pins, washers, and nut.
5. Position tube assembly (5) with threaded nut
toward crossbar for puller screw removal or down
for hydraulic jack removal.
6. For removal with puller screw, attach tube (5) to
each clevis with bolts (2) and nuts (3). Place pad
(4) in nut and thread puller screw (6) into nut from
bottom. Tighten until pad is solid against gearbox
shaft. For best results, strike head of puller screw
with a hammer while tightening with a wrench.
7. For removal with a jack, attach tube to each clevis
with puller links (7), bolts (2), and nuts (3). Place
jack on tube with end of jack pressing against
gearbox shaft. Slowly apply force with jack.
NOTE: Hydraulic jack will not operate if tipped
more than 90 degrees. Use care to prevent bend-
ing crossbar during removal.
