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 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.
8.
Insert protective washer (8) by hand. Install snap ring (21) and position it
together with dual lip seal (18) by pressing it into position. Verify that
snap ring 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.
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 spacer (12) over input shaft (3) and press bearing 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 .3 mm (0.012"), insert shim between input shaft (3)
and rear bearing (7). Repeat until end float is less than .3 mm (0.012").
Check rotational torque by hand. The torque should be less than .25 N-m
(2.2 lbs-inch).
16.
Check that the gear backlash is between .15 mm (0.006") and .41 mm
(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.

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.
Gearbox Installation
NOTE:
Gearbox is heavy: do not attempt to move without mechanical assis-
tance.
1.
Set gearbox on gearbox stand and fasten with bolts and nuts. Torque
bolts to 237 N-m (175 lbs-ft).
2.
Attach drive sheave to output shaft. Secure using castle nut and
hardware previously removed.
3.
Attach gearbox stand to mower using four flanged 1/2" lock nuts.
DRIVE SHEAVE INSTALLATION
1.
When gear stand is installed on mower, dimension A (from the top of the
mower deck to the center line of the drive pulley) must be 61.9 ±.8 mm
(2-7/16" ±1/32"). This is a critical dimension and must be carefully
adjusted for proper belt life. Add or subtract shim washers under idler
pulley (3) to align with drive pulley (4).
2.
Tighten gear stand hardware.
3.
Fill gearbox half full with SAE 90W gear lube.
MAN1260 (4/09/2018)
4.
Check level after waiting five minutes to permit lube to work through
bearings. Add lube, if necessary, until gearbox is half full.
5.
Replace driveline shield. Attach driveline to gearbox.
