16.
Inspect gears for broken teeth and wear. Some wear is normal and will
show on loaded side. Forged gear surfaces are rough when new. Check
that wear pattern is smooth.
17.
Inspect vertical and horizontal shafts for grooves, nicks, or bumps in the
areas where the seals seat. Resurface any damage with emery cloth.
18.
Inspect housing and caps for cracks or other damage.
SEAL REPAIR - DS10.40E
(Figure 20)
Vertical Shaft Seal Repair - DS10.40E
1.
Disconnect and remove the driveline from the gearbox.
2.
Remove vent plug (3) and siphon gear lube from housing through this
opening.
3.
Remove crossbar (see Hydraulic jack will not operate if tipped more than
90-degrees. Use care to prevent bending crossbar during removal. on
page 25).
4.
Remove vertical shaft seal (16). Replace with new seal (see Seal
Installation on page 20).
Vertical seal should be recessed in housing. Horizontal seal should be
pressed flush with outside of housing.
NOTE:
Distortion to seal cage or damage to seal lip will cause seal to
leak.
5.
Fill gearbox with SAE 80W or 90W gear lube until it runs out the level
plug.
6.
Remove and replace any seal damaged in installation.
Horizontal Shaft Seal Repair - DS10.40E
1.
Disconnect and remove the driveline from the gearbox.
2.
Remove vent plug (3) and siphon gear lube from housing through this
opening.
3.
If the leak occurred at either end of horizontal shaft (spindle gearbox),
remove oil cap (24) and/or oil seal (10). For splitter gearbox (Figure 21)
use oil seals (11) and (17). Replace with new one (refer to Seal
Installation, page 20).
4.
Fill gearbox with SAE 80W or 90W gear lube until it runs out the level
plug.
Assemble Gearbox - DS10.40E
1.
Clean housing, paying specific attention to areas where gaskets will be
installed.
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 output bearings (15) in the housing, using a round tube of the
correct diameter and a hand press.
MAN1256 (3/23/2018)
4.
Slide output shaft (19) through both bearings (15) until it rests against
bearing (6).
5.
Slide shim (5) over output shaft (19).
6.
Press gear (13) onto output shaft (19) and secure with washer (25),
castle nut (12), and cotter pin (18).
7.
Apply grease to lower seal lips (16) and press seal (16) over output shaft
(19), using a tube of the correct diameter. Be sure not to damage the seal
lip.
Press in housing so that seal is recessed. Install protective screen (17)
and position it together with dual lip seal (16) by pressing it into position.
Verify that snap ring is seated correctly.
8.
Press bearing (7) into the housing, using a round tube of the correct
diameter and a hand press. Secure with shim (5) and snap ring (9).
9.
Secure snap ring (9) on input shaft (11) if not already secure.
10.
Place gear (6) through top of housing and align gear (6) and gear (13) so
that gear teeth are a match.
11.
While holding gear (6) in place, slide input shaft (11) through gear (6) and
bearing (7). Align splines on shaft (11) and gear (6).
12.
Slide spacer (7) over input shaft (11) and press bearing onto input shaft
(11), using a round tube of the correct diameter and a hand press.
13.
Slide shim (5) over input shaft (11) and secure with snap ring (9).
14.
Check input shaft end float by moving the input shaft (11) by hand. If end
float is higher than 0.3 mm (0.012"), insert shim between input shaft (11)
and rear bearing (7). Repeat until end float is less than 0.3 mm (0.012").
Check rotational torque by hand. The torque should be less than .24 N-m
(2.2 lbs-inch).
15.
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.
16.
Press in input oil seal (10), using tube of correct diameter. Be careful not
to damage seal lip.
17.
Press oil cap (24) on to cover the rear of housing, using a tube of the
correct diameter.
18.
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.
19.
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.
Reinstall Gearbox - DS10.40E
NOTE:
Gearbox is heavy: do not attempt to move without mechanical
assistance.
1.
Set gearbox on cutter and fasten with bolts and nuts. Torque bolts to 407
N-m (300 lbs-ft).
2.
Attach crossbar (see Hydraulic jack will not operate if tipped more than
90-degrees. Use care to prevent bending crossbar during removal. on
page 25).
