00:00:00,000 --> 00:00:15,833
6. While leaving the conical mount buffer stud and lock nuts tight, use a 15/16-inch wrench to remove the four alternator conical mount base plate bolts at the four corners of each conical mount, and save all hardware for reuse.

2
00:00:15,833 --> 00:00:26,375
<b>Note:</b> Alternator Conical Mounting Plate Bolt Wrench (TESCO T85891) may be used to access the inside conical mount base plate bolts.

3
00:00:26,375 --> 00:00:37,125
<b>Note:</b> Removal of the inside, aux cab end, conical base plate bolt is accomplished by first removing the inside, engine end, base plate bolt.

4
00:00:37,125 --> 00:00:45,792
<b>Warning:</b> Improper handling of the hydraulic wrenches or use of an incorrect reaction arm may result in serious injury or death.

5
00:00:45,792 --> 00:00:51,250
Follow all tool manufacturer safety procedures when operating these tools.

6
00:00:51,250 --> 00:01:01,083
<b>Caution:</b> While loosening the torsion bar nuts, to prevent hydraulic tool damage, wood blocks may need to be inserted between the tool and the platform.

7
00:01:01,083 --> 00:01:10,750
<b>Note:</b> Changing the hydraulic wrench from tightening to loosening and vice versa is accomplished by flipping the wrench by 180°.

8
00:01:10,750 --> 00:01:34,208
7. Using a 2-1/16-inch socket and either a HYTORC Stealth 2 or other hydraulic head rated for higher than 1,600 lb.-ft. (2,169 Nm), loosen the alternator bottom flange nuts and remove the 1-3/8-inch torsion bar base bolts, and save all hardware for reuse.

9
00:01:34,208 --> 00:01:39,583
<b>Note:</b> It may be possible to remove the torsion bar without disturbing the wedges.

10
00:01:39,583 --> 00:01:45,750
After removing the base bolts and loosening the nuts, attempt to move the torsion bar base with a pry bar.

11
00:01:45,750 --> 00:01:55,250
If the base can be moved free of its wedges, while lifting the engine-alternator, push the bar towards the engine until it disengages from the wedges.

12
00:01:55,250 --> 00:02:11,250
8. If the torsion bar base cannot be freed of wedge engagement by prying inboard, cut off the tack welds holding the torsion bar base fixed, mark each wedge with its location, remove the torsion bar from its base, and save all hardware for reuse.

13
00:02:11,250 --> 00:02:17,042
<b>Caution:</b> Do not position the engine support blocks on the platform weld seam.

14
00:02:17,042 --> 00:02:31,667
9. With the conical base plate bolts removed and the torsion bar disengaged from its wedged base, from the rear engine centerline lifting eye, lift the engine rear and alternator just enough to install the 4- to 6-inch blocks.

15
00:02:31,667 --> 00:02:47,542
10. After installing the blocks, lower the engine-alternator onto the blocks, remove the alternator bottom flange nuts, and completely remove or slide the torsion bars back far enough that they no longer engage the alternator bottom flanges.
