13.
Install sleeve on shaft and press sleeve and bearing into housing until all
free play is removed and there is a very light drag on bearings (similar to
adjusting front wheel bearings on an automobile). Check by spinning
spindle. It should turn freely.
14.
Be careful not to over tighten bearings. Proper bearing adjustment is
essential to good bearing life.
15.
If you over tighten bearings, hold spindle housing and rap spindle shaft
with a lead hammer.
16.
Carefully press top seal in with spring up. Top seal should be flush with or
to within 1.6 mm (1/16") above the housing.
17.
Rotate housing on spindle shaft, checking for free movement.
18.
Install grease fitting in spindle shaft.
Spindle Installation
NOTICE
■
Pulley installation sequence is very important for bearing life. Fol-
low the sequence exactly.
1.
Install spindle through bottom of mower and secure with four mounting
bolts.
2.
Install pulley and split taper bushing with integral key on spindle shaft.
Make sure bushing is in contact with sleeve on spindle shaft.
3.
Alternately tighten split taper bushing cap screws to 12 lbs-ft.
4.
Install toothed lock washer and nut on spindle shaft. Tighten nut until
snug. Bend up edge of lock washer against a flat side on nut.
GEARBOX REPAIR
Read this entire section before starting any repair. Many steps are dependent
on each other.
Repair to this gearbox is limited to replacing bearings, seals, and gaskets.
Replacing gears, shafts, and a housing is not cost effective. It is more econom-
ical to purchase a complete gearbox if repair to anything other than replace-
ment of bearings, seals or gaskets is required.
Fill gearbox with SAE 80W or 90W gear lube until it runs out the side level plug.
Inspect gearbox for leakage and bad bearings.
Leakage is a very serious problem and must be corrected immediately.
Bearing failure is indicated by excessive noise and side to side or end play in
gear shafts.

1.
Disconnect and remove the rear driveline from the gearbox.
2.
Remove vent plug (10) and siphon gear lube from housing through this
opening.
3.
Remove gearbox stand (2) from mower deck by removing four flanged
lock nuts (6).
4.
Remove drive shield from gearbox.
5.
Remove castle nut (13) and hardware from output shaft of gearbox.
6.
Remove sheave (1) from gearbox.
7.
Remove four bolts (8) that attach gearbox to gearbox stand and remove
gearbox.
Seal Replacement
Recommended sealant for gearbox repair is Permatex® Aviation 3D Form-A-
Gasket or equivalent.
Leakage can occur at the vertical or horizontal gaskets and shaft seals.
Leakage at the horizontal gasket or seal can be repaired without removing the
gearbox from the cutter.

Installation
Figure 19
NOTE: Proper seal installation is important. An improperly installed
seal will leak.
1.
Clean area in housing where seal outer diameter (OD) seats.
Apply a thin coat of Permatex.
2.
Inspect area of shaft where seal seats. Remove any burrs or
nicks with an emery cloth.
3.
Lubricate gear shaft and seal lips.
4.
Place seal squarely on housing, spring-loaded lip toward
housing. Select a piece of pipe or tubing with an OD that will sit
on the outside edge of the seal but will clear the housing. Tubing
with an OD that is too small will bow seal cage and ruin seal.
5.
Carefully press seal into housing, avoiding distortion to the
metal seal cage.
Gearbox Disassembly (Figure 20)
1.
Remove top cover (22) from housing. Turn gearbox upside down and
pour out remaining gear oil from gearbox.
2.
Remove oil cap (20) (to be replaced).
3.
Remove snap ring (10) and shim (13) from input shaft (3).
4.
Support gearbox in hand press and push on input shaft (3) to remove
bearing (7).
5.
Remove gear (1) from inside housing.
