14. Support housing upside down (top cover surface) and remove bottom
bearing (6) by using a punch and hammer from the bottom side of the
housing.
15. Inspect gears for broken teeth and wear. Some wear is normal and will
show on loaded side. Forged gear surfaces are rough when new. Check
that wear pattern is smooth.
16. Inspect vertical and horizontal shafts for grooves, nicks, or bumps in the
areas where the seals seat. Resurface any damage with emery cloth.
17. Inspect housing and caps for cracks or other damage.
Assembly (Figure 12)
1. Clean housing, paying specific attention to areas where gaskets will be
installed.
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 shim (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.
8. 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.
9. 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).
10. Secure snap ring (11) on input shaft (3) if not already secure.

Removal from Cutter
1. Disconnect and remove all drivelines from gearbox.
2. Remove the four cap screw and lock washers that secure gearbox to
cutter, and remove gearbox.
NOTE: Gearbox is heavy: do not attempt to move it without mechanical
assistance.
Disassembly
Centre Shaft
1. Remove plug from side of gearbox and pour out the gear oil.
2. Remove seal (11, to be replaced) from the front and rear of the centre
shaft (14).
3. Remove snap ring (10) and shim (12) from the front and rear of the
centre shaft (14).
4. Support gearbox in a hand press and push on the rear of the centre shaft.
5. Remove bearing (13) from centre shaft (14).
6. Remove six cap screws (20) and top cover (21) from the gearbox
housing.
7. Remove gear (17) and bearing (16).
8. Snap ring (15) does not have to be removed from shaft (14) unless it is
damaged.

Gearbox
Figure 12
11. Place gear (1) through top of housing and align gear (1) and gear (5) so
that gear teeth are a match.
12. While holding gear (1) in place, slide input shaft (3) through gear (1) and
bearing (7). Align splines on shaft (3) and gear (1).
13. Slide shim (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.
14. Slide shim (13) over input shaft (3) and secure with snap ring (10).
15. Check input shaft end float by moving the input shaft (3) by hand. If end
float is higher than .30 mm (0.012"), insert shim between input shaft (3)
and rear bearing (7). Repeat until end float is less than .30 mm (0.012").
Check rotational torque by hand. The torque should be less than .25 Nm
(2.2 lbs-inch).
16. Check that the gear backlash is between .15 Nm (0.006") and .41 Nm
(0.016"). You should not have to adjust the backlash.
17. Press in input oil seal (19), using tube of correct diameter. Be careful not
to damage seal lip.
18. Press oil cap (20) on to cover the rear of housing, using a tube of the
correct diameter.
19. Place top cover (22) on top of housing and secure with six cap screw
(23).
20. 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.
21. Remove gearbox from water and dry off with compressed air. Add SAE
80W or 90W EP oil to proper level. Tighten all plugs.
Reinstallation
NOTE: Gearbox is heavy: do not attempt to move without mechanical
assistance.
1. Set gearbox on cutter and fasten with bolts and nuts. Torque bolts to 407
Nm (300 lbs-ft).
2. Attach crossbar (Crossbar Installation, page 24).
Side Shaft
9. Remove seal (2, to be replaced) from the output shaft (1).
10. Remove snap ring (4) and shim (8) from output shaft (1).
11. Support gearbox in hand press. Using a punch through the front opening
of the gearbox and, push shaft (1) and bearing (5) out the backside of
housing.
12. Remove gear (6) from inside housing.
13. Remove bearing (7) and shim (8) by using a hammer and punch through
front opening of the gearbox and force them out the backside of the
housing.
14. Repeat steps 7 through 11 for opposite side shaft.
Inspect Components
15. Inspect gears for broken teeth and wear. Some wear is normal and will
show on the loaded side of the teeth. Forged gear surfaces are rough
when new. Check that wear pattern is smooth.
16. Inspect shafts for grooves, nicks, or bumps in the areas where seals seat.
Resurface any damage with emery cloth or replace shaft.
17. Inspect housing and caps for cracks or other damage.
