7. If traction band is replaced, the new band will have
an ink mark on the upper end of the band (Fig. 47).
8. Carefully fit traction shaft with band to the planetary
assembly and gearbox base taking care not to distort
traction band. Traction band should easily slide over
traction drum during installation. If traction band is im-
properly placed on the traction shaft or if the band is dis-
torted, it will not fit easily on the drum. Check that
planetary assembly is free to rotate with band installed.
Note: If gearbox is still attached to engine, traction lever
on engine side of gearbox should be installed onto trac-
tion shaft as shaft is installed into gearbox.
9. Rotate differential shaft to verify that all gears and
shafts are meshed properly.
10.Use dowel pins to position gasket to gearbox base.
11. Lubricate short differential axle shaft. Position gear-
box cover to shafts and fit cover to the gearbox base.
12.Position drive shaft plate to gearbox with three fas-
teners: two socket head screws (shorter) and one cap
screw with lockwasher. Install four socket head screws
(longer) and washers in remaining holes in cover.
Torque gearbox fasteners from 120 to 140 in–lb (137 to
159 kg–cm) in the sequence shown in Figure 48.
13.Place traction drive lever onto gearbox shaft noting
location of alignment splines on shaft and lever. Mount
traction lever with cable boss outward (Fig. 49). Secure
lever with cap screw and locknut. Parking brake lever
installation should be done with cable attached to lever
as gearbox is being installed on machine.
14.Check gearbox operation:
A. Engage and disengage clutch, brake band, and
traction band. Check for smooth engagement.
B. Turn one differential axle shaft and check that
other shaft rotates in opposite direction.
C. If smooth operation is not detected, correct prob-
lem before completing assembly.
15.Install reel drive assembly to the gearbox (Fig. 41):
A. Apply anti–seize lubricant to the bore of the reel
drive pulley. Place woodruff key in gearbox shaft and
slide pulley and pulley washer onto shaft. Thread
flange nut onto shaft.
B. Position reel drive belt over pulleys and properly
tension belt (see Transmission Coupler Drive Belt
Adjustment in this chapter).
C. Tighten flange nut to secure pulley.
16.Mount gearbox to machine (see Gearbox Installation
in this section).
