1
00:00:00,000 --> 00:00:07,000
<b>Caution:</b> Do not allow dirt, water, or other contamination to enter the crankcase through the removed covers.

2
00:00:07,000 --> 00:00:09,542
Contamination can cause engine damage.

3
00:00:09,542 --> 00:00:13,100
Ensure the open crankcase is safeguarded against contamination.

4
00:00:13,100 --> 00:00:25,958
11. Remove the alternator guards, also referred to as the alternator ventilation grates, from both sides of the engine to provide access to the engine-alternator coupling.

5
00:00:25,958 --> 00:00:35,083
<b>Warning:</b> Improper handling of the hydraulic wrenches or use of an incorrect reaction arm may result in serious injury or death.

6
00:00:35,083 --> 00:00:40,708
Follow all tool manufacturer safety procedures when operating these tools.

7
00:00:40,708 --> 00:00:50,250
<b>Warning:</b> Before rotating the crankshaft with the engine barring-over device, always check that all personnel and tooling are safely clear of engine movement.

8
00:00:50,250 --> 00:00:56,333
12. Install the barring-over device and open the compression release valves.

9
00:00:56,333 --> 00:01:31,250
13. Bar over the engine as needed to access and remove the 30 bolts coupling the engine to the alternator rotor using either a 20-inch (508-mm) long or longer ¾-inch (19.05-mm) drive breaker bar and a 1-1/8-inch socket or a 24-inch (610-mm) long or longer 1-1/8-inch heavy-duty tubular box end wrench to initially loosen the bolts and a 90° air ratchet for rapid removal.

10
00:01:31,250 --> 00:01:41,292
<b>Warning:</b> A Tier 2 non-VSPD alternator weighs approximately 16,500 lbs. (7,484 kg).

11
00:01:41,292 --> 00:01:50,500
Before use, each component in the lift rigging system must be inspected, qualified, and confirmed to have an adequate lift capacity rating.

12
00:01:50,500 --> 00:01:55,458
Failure to perform these tasks may result in personal injury or death.

13
00:01:55,458 --> 00:02:13,958
14. To a properly rated crane, attach an adjustable three-leg rigging system or, more preferably, a turnbuckle-equipped rigging system that allows for a level lift of the alternator, then attach the rigging to the alternator and adjust the hooks or turnbuckle for a level lift.

14
00:02:13,958 --> 00:02:26,708
15 With crane tension applied to lift the rigging, remove the four alternator top flange mounting bolts using a ¾-inch air impact wrench and a 2-1/16-inch socket.
