TM 9-2320-361-34 I 15-42. INTERMEDIATE CASE MAINTENANCE (Contd) 8. 9. 10. 11. 12. Install boring case (5) on intermediate case (2) (para. 15-38). Look through inspection hole (4) of boring case (5) and ensure that heel of second reduction drive pinion (9) is alined with toe of rack drive gear (6), and toe of second reduction feed pinion (8) is alined with heel of rack feed idler gear (7). If adjustment of feed pinion (8) is required, refer to subtask of this paragraph. If adjustment of drive pinion (9) is required, refer to subtask g. Look through power leveler shaft hole (1) on intermediate case (2) and ensure that toe of first reduction drive pinion (12) is alined with toe of drive gear (10) and heel of first reduction feed pinion (3) is alined with heel of gear and hub (11). NOTE Depth of first reduction feed and drive pinions are adjusted by adding or removing the appropriate shims (para. 15-38). Position dial indicator through power leveler shaft hole (1) and against drive gear (10) and measure backlash between drive gear (10) and first reduction drive pinion (12). Backlash should be 0.006-0.016 in. (0.15-0.41 mm). If adjustment of drive gear (10) is required, refer to subtask h. Place dial indicator against gear and hub (11) and measure backlash between gear and hub (11) and first reduction drive pinion (12). Backlash should be 0.006-0.016 in. (O. 15-0.41 -mm). If adjustment of gear and hub (11) is required, refer to subtask i. 15-172
