Typical steps to assemble the gear case after positioning the nose of the traction motor down on wooden blocks are as follows:

2
00:00:07,917 --> 00:00:17,625
<b>Note:</b> Gear cases and U-tubes made prior to October 1989 may require modification to bring them to the latest revision level.

3
00:00:17,625 --> 00:00:25,458
Three pipe plugs should be installed on each gear case and a gear case to U-tube mounting lug should be welded to each U-tube.

4
00:00:25,458 --> 00:00:29,458
If required, contact your Field Services representative.

5
00:00:29,458 --> 00:00:40,708
<b>Warning:</b> The traction motor, wheels, and axle assembly weighs approximately 12,000 lbs. (5,443 kg).

6
00:00:40,708 --> 00:00:45,667
Ensure that the crane and cables are adequate to lift and move the assembly.

7
00:00:45,667 --> 00:00:51,667
<b>Note:</b> Only an approved sealant is to be used to seal the metal and plastic joints.

8
00:00:51,667 --> 00:00:55,000
The curing time for the sealant is 24 hours.

9
00:00:55,000 --> 00:01:04,458
In most cases, a 0.25-inch (6.4-mm) minimum bead of the approved sealant is required.

10
00:01:04,458 --> 00:01:12,958
However, at the gear case split line a 0.13-inch (3.2-mm) maximum bead should be used.

11
00:01:12,958 --> 00:01:27,708
1. Clean the surface of the bull gear flinger on which the motor-side gear case seal (gutter) rides, then lubricate this surface with D50E25C gear oil or equivalent.

12
00:01:27,708 --> 00:01:35,000
2. Install the motor-side axle seal to the axle assembly with the lip of the seal located over the flinger.

13
00:01:35,000 --> 00:01:45,583
<b>Note:</b> The latch should be located on the left (bottom half of the gear case) and the cut-out notch should be located on the right (top half of the gear case).

14
00:01:45,583 --> 00:01:55,833
3. Add a 0.25-inch (6.4-mm) minimum bead of the approved sealant in the groove and latch the seal.

15
00:01:55,833 --> 00:02:03,917
<b>Note:</b> Do NOT apply sealant in excess of a 0.25-inch (6.4-mm) bead at the latch joint.

16
00:02:03,917 --> 00:02:08,500
Ensure that all sealing surfaces are not pinched or folded.
