Gearbox Disassembly

Refer to Figure 18.

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.

6. Remove oil seal (19) from front of housing (to be

replaced).

7. Remove snap ring (10) and shim (13) from front of

housing (2).

8. Remove input bearing (7) by using a punch and

hammer from outside of housing.

9. Support housing in vise in a horizontal position.

10. The castle nut (15) and cotter pin (25) are already

removed with the drive sheave. Remove snap ring
(21), washer (8), and seal (18).

11. Remove cotter pin (9), castle nut (14), and washer

(17) from output shaft (4).

12. Remove output shaft (4) by using a punch and

hammer and tap on top to drive down.

13. Remove gear (5) and shim (16) from inside

housing.

14. Remove bearing (26) by using a punch and

hammer from the top, outside the housing.

15. Support housing upside down (top cover surface)

and remove bearing (6) by using a punch and
hammer from the bottom side of the housing.

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.

Gearbox Reassembly

Refer to Figure 18.

NOTE:  Repair to this gearbox is limited to replacing
bearings, seals, and gaskets. Replacing gears, shafts,
and a housing is not cost effective. Purchasing a com-
plete gearbox is more economical.

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 (6 & 26) in the housing,

using a round tube of the correct diameter and a
hand press.

4. Slide output shaft (4) through both bearings (6 &

26) until it rests against bearing (6).

5. Slide shim (16) over output shaft (4).

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 0.012",
insert shim between input shaft (3) and rear
bearing (7). Repeat until end float is less than
0.012". Check rotational torque by hand. The
torque should be less than 2.2 lbs-inch.

16. Check that the gear backlash is between 0.006"

and 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.
