) and 4 lock washers that attach
the gearbox assembly to the gearbox brackets.
8. Remove the 3 carriage screws, 3 flange nuts, 3 washers, and 3 mounts that
attach the left and right gearbox brackets (items 3 and 9 in
) to the
deck mounting plate, and remove the brackets from the deck.

Drain the lubricant from the gearbox.
10. Remove the 2 set screws that attach the taper lock bushing to the drive
pulley on the gearbox shaft.
11. Install 1 of the removed set screws into the threaded hole of the bushing.
Tighten the set screw to loosen the bushing from the pulley hub (
).
12. Slide the bushing and pulley from the gearbox shaft.
13. Locate and retrieve the woodruff key.
14. If necessary, remove and replace the oil seals and oil caps in the gearbox
(
).
Note:
If internal gearbox wear or damage occurs, gearbox replacement is
necessary. The internal gearbox components are not available.
Installing the Gearbox
1. If oil seals or oil caps were removed from the gearbox, install new seals and
caps to the gearbox.
2. Clean the gearbox output shaft, pulley ID (inner diameter), and taper lock
bushing.
3. Position the woodruff key, pulley, and then the taper lock bushing to the
gearbox output shaft. Slide the bushing to the shoulder on the shaft. Align
the threaded holes of the pulley with the non-threaded holes of the bushing.
4. Apply oil to the threads of the set screws and install the screws into the
threads of the pulley (
). Alternately and evenly torque the set
screws to
20 to 28 N∙m (180 to 250 in-lb)
.
5. Fill the allen recess in the set screws and bushing threads with grease to
prevent dirt from packing into the crevices.
6. Position the gearbox assembly (with the drive pulley attached) to the deck.
7. Position and attach the left and right gearbox brackets (items 3 and 9 in
) to the deck mounting plate with the 3 carriage screws, 3 flange
nuts, 3 washers, and 3 mounts.
8. Secure the gearbox assembly to the gearbox brackets with the 4 bolts (item
10 in
) and 4 lock washers.
9. Connect the PTO driveshaft to the gearbox; refer to
Driveshaft (page 6–26)
.
10. Install the drive belt and deck covers to the cutting deck.
11. Torque the plug in the gearbox to
19.8 N∙m (175 in-lb)
. Fill the gearbox with
approximately 355 ml (12 fl oz) of SAE 80W90 gear lubricant.
