Disassemble Steering Clutches
Start By:
a. remove steering clutches
1. Remove brake band (2) and outer drum (1) from the steering clutch.
2. Install tooling (B) to the end of the clutch shaft and install it in a vise.
3. Remove lock (3). Use tooling (A) and loosen nut (4) until it is even with the top of the shaft.
 |
Do not remove nut (4). This will keep the drum on the shaft when it is loosened from the taper on the shaft. |
 |
4. Remove the steering clutch from the vise. The weight is approximately 45 kg (100 lb).
5. Use tooling (D) as shown to push the shaft from the inner drum. Remove tooling (D) and nut (4). Remove the shaft from the steering clutch.
6. Install tooling (H) on the other side of the steering clutch and install it in a vise.
7. Remove two setscrews (5). Use tool (E) and remove spanner nut (6) from the plate assembly.
8. Bend locks (7) down and remove bolts (8) that hold the yoke in place.
9. Remove yoke (9) from the plate assembly.
10. Use a pry bar on each side of the bearing cage and remove bearing cage (10) from the plate assembly.
11. Remove retaining ring (11) from bearing cage (10).
12. Remove bearing (12) from bearing cage (10).
13. Put two pieces of wood (13) on tool (F), as shown, as a support for the steering clutches. Install drum (1). Make an alignment of the centers of the clutches and drum (1).
14. Install tooling (C), as shown, and put the steering clutch spring under compression.
15. Remove locks (14) from the studs.
16. Slowly release the pressure on the steering clutch springs. Remove tooling (C).
NOTE: Only oil-cooled steering clutches have spacers located under springs (16).

12. If a replacement spanner nut is needed, drill two holes 5.16 mm (.203 in) to a depth of 9.65 mm (.38 in) with the center line of the spanner nut to the holes 36.58 mm (1.44 in) apart as shown. Use a 1/4 " - 20 NC tap to make threads in the spanner nut to a depth of 7.87 mm (.31 in).
13. Use tool (P) and install spanner nut (6). Tighten the spanner nut to a torque of a 470 ± 70 N·m (350 ± 50 lb ft).
14. Install setscrews (5) that lock the spanner nut (6) in place.
