2.
Wash housing and all components thoroughly. Select a clean area for
gearbox assembly. Replace all seals, bearings, and gaskets. All parts
must be clean and lightly oiled before reassembling.
3.
Insert both output bearings (6) in the housing, using a round tube of the
correct diameter and a hand press.
4.
Slide output shaft (4) through both bearings (6) until it rests against top
bearing (6).
5.
Slide shim (16) over output shaft (4).
6.
Press gear (5) onto output shaft (4) and secure with washer (17), castle
nut (14), and cotter pin (9).
7.
Apply grease to lower seal lips (18) and press seal (18) over output shaft
(4), using a tube of the correct diameter. Be sure not to damage the seal
lip.
Press in housing so that seal is recessed. Press protective seal (8) until
seated flush with housing. Verify that the seal (8) is seated correctly.
8.
Press bearing (7) into the housing, using a round tube of the correct
diameter and a hand press. Secure with shim (13) and snap ring (10).
9.
Secure snap ring (11) on input shaft (3) if not already secure.
10.
Place gear (1) through top of housing and align gear (1) and gear (5) so
that gear teeth are a match.
11.
While holding gear (1) in place, slide input shaft (3) through gear (1) and
bearing (7). Align splines on shaft (3) and gear (1).
12.
Slide spacer (12) over input shaft (3) and press bearing (7) onto input
shaft (3), using a round tube of the correct diameter and a hand press.
13.
Slide shim (13) over input shaft (3) and secure with snap ring (10).
14.
Check input shaft end float by moving the input shaft (3) by hand. If end
float is higher than .31 mm (0.012"), insert shim between input shaft (3)
and rear bearing (7). Repeat until end float is less than .31 mm (0.012").
Check rotational torque by hand. The torque should be less than .75 N-m
(2.2 lbs-inch).
15.
Check that the gear backlash is between .15 to .41 mm (0.006" to
0.016"). You should not have to adjust the backlash.
16.
Press in input oil seal (19), using tube of correct diameter. Be careful not
to damage seal lip.
17.
Press oil cap (20) on to cover the rear of housing, using a tube of the
correct diameter.
18.
Place top cover (22) on top of housing and secure with six cap screw
(23).
19.
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.
20.
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.
Reinstall Gearbox
NOTE: Gearbox is heavy: do not attempt to move without mechanical assis-
tance.
1.
Set gearbox on cutter and fasten with bolts and nuts. Torque bolts to 406
N-m (300 lbs-ft.).
2.
Attach crossbar (see Crossbar Installation, page 18).
CROSSBAR REMOVAL
1.
It is necessary to gain access to bottom side of cutter for crossbar
removal. See BLOCKING METHOD, page 12.
NOTE: You will need to use either the puller screw (Item 6, Figure 19) or
a small hydraulic jack to remove the crossbar.
2.
Remove blade pin hardware, blade pins and blades from crossbar.
3.
Remove retaining wire from bottom of crossbar and remove nut and
washer.
MAN1255 (3/19/2018)
4.
Refer to Figure 19. Attach 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 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°. Use care
to prevent bending crossbar during removal.
