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.
