3. Select a clean work area to assemble gearbox.
4. Replace all seals, bearings, and gaskets.
5. All parts must be clean and lightly oiled before assembly.
Side Shaft
6. Insert bearing (7) and shim (8) in housing using a round tube of the same
size diameter and a hand press.
7. Place gear (6) inside the housing and slide output shaft (1) through gear
(6) and into bearing (7).
8. Slide bearing (5) and shim (8) over output shaft. Secure with snap ring
(4).
9. Check end play of shaft by moving it in and out. If end play is more than
.30 mm (0.012"), insert another shim (8) between snap ring and bearing.
Repeat process until end play is less than .30 mm (0.012").
10. Check rotational torque. Torque should be less than .25 Nm (2.2 lbs-inch)
gear.
11. Place seal (2) over shaft and press into housing using a tube of the same
diameter. Seal should be flush with housing when properly installed.
12. Repeat steps 6 through 10 for opposite side shaft.
Centre Shaft
13. Place gear (17) inside housing and slide centre shaft (14) through the
gear from the front of the housing.
14. Slide bearings (16 & 13) and shims (12) over each end of the centre shaft
(14). Secure bearings into position using snap rings (10).
15. Check end play of shaft by moving it in and out. If end play is more than
.30 mm (0.012"), insert another shim (12) between snap ring and bearing.
Repeat process until end play is less than .30 mm (0.012").

16. Check rotational torque. Torque should be less than .25 Nm (2.2 lbs-inch)
gear.
17. Check gear backlash, backlash should be between .15 mm to .41 mm
(0.006" to 0.016"). You should not have to adjust for backlash.
18. Place seal (11) over shaft and press into housing using a tube of the
same diameter. Seal should be flush with housing when properly
installed. Repeat process for opposite end shaft.
Check Gearbox
1. Place top cover (21) on housing and secure into position using six cap
screws (20).
2. Check gearbox for leaks by: plugging all holes except one, applying 27.6
kPa (4 psi) of compressed air, and immersing gearbox in water. Verify
gearbox does not leak.
NOTE: Excessive air pressure will damage seals.
3. Remove gearbox from water and dry off.
4. Remove upper plug (3) on right side of housing. Add SAE 80W or 90W
EP oil until it runs out side level hole. Replace plug.
5. Install breather (18) in top cover.
Reinstallation on Cutter
NOTE: Gearbox is heavy: do not attempt to move it without mechanical assis-
tance.
1. Place gearbox on cutter and secure into position using four cap screws
and lock washers.
2. Torque hardware to 407 Nm (300lbs-ft).
3. Attach all drivelines to gearbox.
4. Install all shields.
