00:00:00,000 --> 00:00:04,417
Typical steps to couple the engine and the alternator are as follows:

2
00:00:04,417 --> 00:00:14,208
<b>Note:</b> The following steps are applicable for the coupling of an alternator to an engine that is already mounted on the locomotive platform with its rear supported on blocks.

3
00:00:14,208 --> 00:00:20,083
1. Install the engine barring over motor and open the compression release valves.

4
00:00:20,083 --> 00:00:26,958
<b>Caution:</b> Do not allow dirt, water, or other contamination to enter the crankcase through the removed covers.

5
00:00:26,958 --> 00:00:29,625
Engine damage can result from contamination.

6
00:00:29,625 --> 00:00:34,083
Ensure the open crankcase is safeguarded against contamination.

7
00:00:34,083 --> 00:00:42,792
2. If not already removed, remove the alternator guards from both sides of the engine to make the engine-alternator coupling accessible. 

8
00:00:42,792 --> 00:00:47,833
3. Prepare the alternator conical mount base plate as follows: 

9
00:00:47,833 --> 00:00:54,000
a. Clean the conical mount base plate with a 120 grit flap wheel. 

10
00:00:54,000 --> 00:01:00,792
b. Apply Lubriplate<sup>®</sup> 630AA to the base plate surface.

11
00:01:00,792 --> 00:01:07,750
c. Apply Molykote<sup>®</sup> 77 paste to the base plate bolt hole threads and to the bolt threads.
