15.
Check gearbox housing for leaks by plugging all holes except one. Apply
27.6 kPa (4 psi) compressed air and immerse the gearbox in water to
verify that there are no leaks.
16.
Remove gearbox from water and dry off with compressed air. Add SAE
80W or 90W EP oil until it runs out of the lower level hole in front cover.
Tighten all plugs.
REINSTALL GEARBOX
NOTE: Gearbox is heavy: do not attempt to move without mechanical
assistance.
1.
Install flex coupler driveline between side gearboxes and center gearbox.
2.
Set gearbox on cutter and fasten with bolts and nuts. Torque bolts to 407
N-m (300 lbs-ft).
CROSSBAR REMOVAL
1.
It is necessary to gain access to bottom side of cutter for crossbar
removal. See BLOCKING METHOD, page 21.
NOTE:
You will need to use either the puller screw (Item 6, Figure 23)
or a small hydraulic jack to remove the crossbar.
2.
To make crossbar removal easier, remove blades as shown in Figure 22.

SIDE DRIVE SERVICE
The drives between the center and side gearboxes contain rubber shock-
absorbing discs. To service or remove the side drives or remove a gearbox, the
flexible coupling must be disassembled.
Remove end yokes by removing nuts (10) and sliding bolt (8 or 9) inward to
clear yoke. Do not remove bolt unless rubber discs (5) are to be serviced.
Remove complete center section by lifting straight up on center shaft (4). The
outer yoke can be slid off gearbox shaft. The inner yoke is held by two set
screws.
Reassemble shaft as shown in Figure 22. End yokes (1 & 2) do not bolt directly
to center shaft (4). Use the special formed washer (6) and bushings (7)
between the rubber discs (5) and under bolt head or nut near rubber disc.
Tighten the nuts (10) evenly until the formed washers (6) are slightly embedded
into the rubber discs. Rubber discs (5) will warp and twist if bolts are overtight-
ened. Tighten set screws on center gearbox shaft only. Grease opposite end of
side drive through grease fitting (11) located on end yoke.
NOTE: Crossbar must be re-timed anytime a crossbar or a side drive is discon-
nected.

3.
Remove cotter pin (20) and castle nut (19) from bottom of crossbar.
4.
Refer to Figure 24. Attach a clevis (1) to each end of crossbar, using
blade pins, spacers, keyhole plates, and blade pin clips.
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 screws
(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),
screws (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 bending crossbar during removal.
