Integral Steering Gear Disassemble Saginaw

Tools Required

1. Remove the housing end plug. Refer to Steering Gear Housing Plug Replacement - Off Vehicle .
2. Remove the side cover. Refer to Steering Gear Pitman Shaft and Housing Cover Replacement - Off Vehicle .
3. Turn the stub shaft (4) clockwise until the pitman shaft teeth (1) and the primary rack piston (3) and the secondary rack piston (2) are disengaged.
4. Turn the stub shaft (4) clockwise until the primary rack piston (3) bottoms in the steering gear housing.



5. Align the end tooth of the pitman shaft with the center groove of the primary rack piston (1) and the secondary rack piston (1).
6. Turn the stub shaft counterclockwise until the housing end plug separates from the steering gear housing.

Important: Do not remove the housing end plug from the secondary rack piston (1) unless replacement of the housing end plug is needed.

7. Remove the secondary rack piston (1).
8. Rotate the stub shaft clockwise until the pitman shaft teeth (2) are free of the rack.
9. Turn the pitman shaft teeth (2) until the teeth (2) are horizontal.



10. Insert J 21552 into the primary rack piston (1) bore with the pilot of J 21552 seated into the end of the pin and worm assembly.
11. Hold J 21552 against the pin and worm assembly while turning the stub shaft counterclockwise. The primary rack piston (1) will be forced onto J 21552 .
12. Hold J 21552 while pulling the primary rack piston (1) toward the handle until the primary piston rack touches the tool flange. This prevents the circuit balls from falling out of the primary rack piston (1).
13. Remove the primary rack piston (1) from J 21552 .
14. Remove the primary rack piston balls.
15. Remove pitman shaft from the steering gear housing (2) by tapping the end of the pitman shaft.
