1
00:00:00,000 --> 00:00:04,667
<b>Caution:</b> Top flange torque values influence web deflection readings.

2
00:00:04,667 --> 00:00:08,500
Never use an impact wrench as a substitute for a torque wrench.

3
00:00:08,500 --> 00:00:15,292
Consistency in dial indicator readings depends on consistent alternator top flange mounting bolt tightness.

4
00:00:15,292 --> 00:00:31,958
<b>Caution:</b> Setting a desired torque using the 0 - 1000 lb.-ft. (0 - 1356 Nm), 1-inch Square Drive Torque Wrench (TESCO T18250) is unique compared to most other torque wrenches.

5
00:00:31,958 --> 00:00:35,458
Ensure the correct dial face scale is used.

6
00:00:35,458 --> 00:00:41,292
<b>Caution:</b> The final torque of the flange bolts must be with a torque wrench or torque controlled tool.

7
00:00:41,292 --> 00:00:47,917
Over torquing or under torquing with an impact wrench could result in the premature failure of the bolts.

8
00:00:47,917 --> 00:01:08,667
12. Torque the four alternator top flange mounting bolts (the inner top flange bolts first followed by the outer top flange bolts) to 650 ± 25 lb.-ft. (881 ± 34 Nm) and repeat this torque pattern to confirm the proper torque.

9
00:01:08,667 --> 00:01:24,917
13. After adjusting the conical mount central buffer lock nuts to lower the plates enough to install the 5/8-inch conical mount base plate bolts to the platform mounting pads, loosely apply the base plate bolts with a 15/16-inch wrench.

10
00:01:24,917 --> 00:01:30,917
<b>Note:</b> The conical mount base plate bolts will be torqued after the alignment is complete.

11
00:01:30,917 --> 00:01:39,083
14. Apply Molykote<sup>®</sup> 77 paste to the torsion bar base hole and the bolt threads.

12
00:01:39,083 --> 00:01:46,333
15. Install the torsion bars through the alternator bottom flange hole leaving the nuts loosely applied.

13
00:01:46,333 --> 00:02:01,917
16. With the conical mount central buffer nuts fully backed off and ample thread showing on the loosely applied conical mount base plate bolts, slightly lift the rear of the engine from the centerline lifting eye just high enough to remove the support blocks.
