Steering Gear Adjustments Saginaw - 710 Model

Tools Required

1. Drain the oil from the steering gear by rotating the steering gear completely several times.
2. Turn the stub shaft (1) from the right wheel stop to the left wheel stop while counting the number of turns.
3. Rotate the stub shaft (1) back half the number of turns to the center position.



4. Place J 7754-01 and a deepwell ¾ inch 12 point socket (1) over the stub shaft in order to check the total preload torque by rotating J 7754-01 through a 180 degree arc either side of the center.
5. Record the highest reading while turning J 7754-01 back over the center position.
6. Turn the stub shaft ½ turn (180 degrees) right or left from the center.
7. Install J 7754-01 vertically on the stub shaft.



8. Turn J 7754-01 20 degrees to the left or the right of the vertical position.
9. Record the reading while turning J 7754-01 back to the vertical position.
10. Subtract this reading from the reading in step 5.
11. If the reading in step 5 is 0.23 N·m (2 lb in), then the steering gear is adjusted properly. If the reading in step 5 is less than 0.23 N·m (2 lb in) proceed with the following adjustments:

11.1.

If the reading in step 5 is at least 0.23 N·m (2 lb in) and not more than 1.13 N·m (10 lb in), the steering gear is adjusted properly. Proceed to steps 12 through 16.

11.2.

If the reading in step 5 is less than 0.23 N·m (2 lb in) or more than 1.13 N·m (10 lb in), proceed to step 12 through 23.

12. Loosen the coupling shield retainer and the lock nut with the steering gear centered.



13. Turn the adjuster nut assembly (1) clockwise using J 42882 . Torque the adjuster nut assembly (1) to 28-31 N·m (21-23 lb ft) and back off 15-25 degrees.
14. Tighten the coupling shield and lock nut (2). Stabilize the adjuster nut assembly (1) while tightening the coupling shield and lock nut (2).
15. Turn the stub shaft 2 turns right or left from the center position.



16. Install J 7754-01 near vertical. Record the torque reading. The torque reading should be 1.60 N·m (14 lb in) while turning J 7754-01 in an arc 20 degrees left or right of the vertical position.



17. With the steering gear in the center position, loosen the preload adjuster nut (2). Ensure the adjusting screw is backed out counterclockwise all the way.
18. Turn the adjuster screw clockwise ½ turn. This prevents the pitman shaft from bottoming out of the side cover.
19. Place J 7754-01 in the vertical position in order to check the preload.
20. Move J 7754-01 90 degrees to the left or the right of the center position. Record the highest torque reading while moving J 7754-01 back to the center position.
21. Tighten the adjuster screw clockwise until the torque reading is 0.68-1.13 N·m (6-10 N·m) higher than the reading taken in the previous step.
22. Tighten the preload adjuster nut (2) to 90 N·m (66 N·m). Ensure the adjuster screw does not turn during tightening.
23. Reinspect the preload after tightening the preload adjuster nut (2).
