1
00:00:00,000 --> 00:00:04,667
<b>Caution:</b> Prevent bending or binding the torsion bar as the engine is lowered.

2
00:00:04,667 --> 00:00:19,208
If the wedges were not removed from the torsion bar base when the alternator was removed, while lowering the engine-alternator, slightly pry the torsion bar towards the engine so that the torsion bar slot properly engages the inboard side of the wedges.

3
00:00:19,208 --> 00:00:27,208
17. With the support blocks removed, lower the engine-alternator assembly to fully rest on the conical mounts.

4
00:00:27,208 --> 00:00:36,000
<b>Caution:</b> The conical mounts need a minimum of 90 minutes under the weight of the alternator to completely settle to a final position.

5
00:00:36,000 --> 00:00:44,750
18. After a minimum of 90 minutes, inspect the conical mounts to ensure full engagement with the alternator flange.

6
00:00:44,750 --> 00:00:48,833
<b>Note:</b> Replace conical mounts if found defective.

7
00:00:48,833 --> 00:00:56,292
<b>Caution:</b> Never begin the alignment process without first setting the conical clearance and torquing the buffer stud locknut.

8
00:00:56,292 --> 00:01:07,750
<b>Caution:</b> If the alternator was lowered to the platform without the conical buffer stud fully unscrewed, it may not be possible to adjust the clearance due to the stud being bound tight against the platform.

9
00:01:07,750 --> 00:01:11,375
Enable stud adjustment by relieving pressure on the stud.

10
00:01:11,375 --> 00:01:17,167
Do this by slightly lifting the engine-alternator assembly from the engine rear lifting lug.

11
00:01:17,167 --> 00:01:33,833
19. If 90 minutes have passed since setting the alternator, before proceeding with alignment, adjust the conical mount clearances with the 4-mm GEVO Conical Mount Stud Clearance Check Set Gauge (TESCO T85500).

12
00:01:33,833 --> 00:01:45,667
20. After adjusting the conical mount clearance, torque the conical stud locknut to 185 lb.-ft. (251 Nm).

13
00:01:45,667 --> 00:01:53,167
<b>Note:</b> For more information on checking and setting the conical clearance, refer to customer-specific documentation.

14
00:01:53,167 --> 00:02:06,167
21. Using a torque wrench and a 2-1/16-inch socket, torque the torsion bar base bolts to the platform to 100 lb.-ft. (136 Nm). 

15
00:02:06,167 --> 00:02:14,667
<b>Warning:</b> Improper handling of the hydraulic wrenches or use of an incorrect reaction arm may result in serious injury or death.

16
00:02:14,667 --> 00:02:20,125
Follow all tool manufacturer safety procedures when operating these tools.

17
00:02:20,125 --> 00:02:36,792
22. Using a 2-1/16-inch socket and either a HYTORC Stealth 2 or other hydraulic head with pressure set for 1,600 lb.-ft. (2,169 Nm), torque the torsion bar nuts.

18
00:02:36,792 --> 00:02:54,875
23. Using a 2-1/16-inch socket and either a HYTORC Stealth 2 or other hydraulic head with pressure set for 1,500 lb.-ft. (2,034 Nm), tighten the 1-3/8-inch torsion bar base bolts.

19
00:02:54,875 --> 00:03:02,958
<b>Caution:</b> Do not disturb the torsion bar bolts or flange nuts from this point forward in the alignment process.

20
00:03:02,958 --> 00:03:10,958
24. If previously removed, re-apply wedges to the torsion bar base block and tack weld in place.
