00:00:00,000 --> 00:00:12,625
<b>Warning:</b> A Tier 2 non-variable speed (non-VSPD) alternator weighs approximately 16,500 lbs. (7,484 kg).

2
00:00:12,625 --> 00:00:21,625
Before use, each component in the lift rigging system must be inspected, qualified, and confirmed to have an adequate lift capacity rating.

3
00:00:21,625 --> 00:00:26,708
Failure to perform these tasks may result in personal injury or death.

4
00:00:26,708 --> 00:00:33,458
<b>Note:</b> An adjustable turnbuckle-type rigging system can be used to evenly lift the various alternator models.

5
00:00:33,458 --> 00:00:41,625
Ask your local rigging supplier to build a similar system with all components appropriately rated for the lifts anticipated.

6
00:00:41,625 --> 00:00:52,167
<b>Warning:</b> To prevent personal injury and potential equipment damage, ensure that the engine cannot be started before removing, installing, or adjusting any engine components.

7
00:00:52,167 --> 00:00:54,958
Open all circuit breakers on the EC panel.

8
00:00:54,958 --> 00:01:08,750
Open the Battery Switch (BS) and then the Maintenance Battery Switch (MBS) or Maintenance Battery Disconnect (MBD), if equipped, to prevent starting attempts.

9
00:01:08,750 --> 00:01:13,083
Apply a warning tag to the Engine Control (EC) switch.

10
00:01:13,083 --> 00:01:21,833
Open the Maintenance Relief Valve (MRV) in order to ensure that any residual fuel pressure in the system is relieved.

11
00:01:21,833 --> 00:01:30,167
<b>Note:</b> To ensure correct tracking procedures, record the serial numbers of the alternator being removed and the one being installed.

12
00:01:30,167 --> 00:01:43,167
<b>Note:</b> A typical 12-cylinder Tier 2 engine is often coupled to a 5GMG205, 5GMG206, or 5GMG210 alternator.

13
00:01:43,167 --> 00:01:47,833
Typical steps to remove the alternator from the diesel engine are as follows:

14
00:01:47,833 --> 00:01:56,833
<b>Note:</b> The following steps are applicable for the removal of an alternator on the locomotive platform with the engine rear supported on blocks.

15
00:01:56,833 --> 00:02:00,958
1. Disconnect the alternator wiring, including:

16
00:02:00,958 --> 00:02:04,208
a. The main output and input wiring.

17
00:02:04,208 --> 00:02:08,125
b. The auxiliary output and input wiring.

18
00:02:08,125 --> 00:02:11,750
2. Prepare the blower cab for removal.

19
00:02:11,750 --> 00:02:15,125
a. Remove all applicable bolts.

20
00:02:15,125 --> 00:02:20,042
b. Remove all cooling air connections to the blower cab.
