2.
Wash housing and all components thoroughly. Select a clean area for
gearbox assembly. Replace all seals, bearings, and gaskets. All parts
must be clean and lightly oiled before reassembling.
3.
Insert upper output bearing cups (25) in the housing and press using a
round tube with the correct diameter.
4.
Slide shims (26) over output shaft (16). Use the same thickness as
removed as a starting point.
5.
Push bearing cone (25) onto output shaft (16). Shims maybe required
between cone (25) and retaining ring (6) to eliminate any space.
NOTE:
Make sure there is no endplay or gaps in this assembly.
6.
Insert output bearing spacer (18) and bearing cone (25) over output shaft
until seats against upper bearing (25). Press lower bearing cup into
position as shown.
7.
Secure output cap (17) with new output seal (16) installed to bottom of
gearbox housing using the four 10mm x 1.5 x 25 cap screws (13) and
lock washers (12). Use shim gaskets (10) and (11) to adjust output
bearings to a rolling torque of 9 to 12 In-lbs.
NOTE:
Be sure output gaskets (10 and 11) are in place. Apply grease
to output seal (16) lip for easy installation.
SPINDLE GEARBOX REPAIR - DS10.40E
Refer to Figure 20.
NOTE:
Replacing gears, shafts, bearings, and seals may not be cost effec-
tive. Purchasing a complete gearbox may be more economical.

Disconnect and remove the driveline from the gearbox.
2.
Remove vent plug (3) and siphon gear lube from housing through this
opening.
3.
Remove cotter pin, washer, and nut from vertical shaft and remove
crossbar (see Hydraulic jack will not operate if tipped more than 90-
degrees. Use care to prevent bending crossbar during removal., page
25).
4.
Remove the four bolts that attach gearbox to cutter and remove gearbox.
Gearbox is heavy; do not attempt to move without mechanical
assistance.
Disassemble Gearbox
1.
Remove 3/8" plug from side of gearbox and pour out gear oil.
2.
Remove oil cap (24) (to be replaced).
3.

8.
Place ball bearing (21) at back of housing and press in socket using a
round tube of the correct diameter and a hand press until fully seated.
9.
Insert input shaft (5) part way through housing and slide gear (3) and
retaining ring (6) over input shaft (5). Keep gear (3) and retaining ring (6)
loose.
10.
Insert input shaft (5) into roller bearing (21) until seated against each
other.
11.
Slide gear (3) forward and attach retaining ring (6) in groove closest to
front of input shaft (5). Slide gear (3) back against retaining ring (6).
12.
Check that the gear backlash is between 0.15 mm and 0.41 mm (0.006")
and 0.016". You should not have to adjust the backlash.
13.
Slide gear spacer (7) and ball bearing (20) on input shaft (5) and secure
with retaining rings (6) and (8).
14.
Slide input seal (4) onto input shaft (5) and press into housing flush with
front using a tube of correct diameter. Be careful not to damage seal lip.
15.
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.
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
