9. Put identification on the battery cable, starter cable and all electric wires as to their location on the rear frame. Disconnect these lines from their location on the rear frame. Put identification on the air lines and the oil lines as to their location on the front frame. Disconnect these lines from their locations on the front frame.
10. Remove all lines, wires and cables that were disconnected from the front and rear frames. Install the lock pin in the wheel lean bar and the front axle. Put blocks under the front wheels so they can not move. Install tooling (A) under the platform on each side of the machine.
11. Put a fork lift truck in position under the rear of the rear frame.
12. Remove the bolts that hold pin (20) to the frame. Install two 3/8" - 16 NC forcing screws (19) in the pin. Remove the pin with the forcing screws.
NOTE: Lift or lower the frame with the fork lift truck to remove any pressure from the pin.
13. Remove bolts (23) that hold plate (21) to the frame. Remove bolts (22) that hold plate (21) to the bottom pin.
14. Remove plate (21) and the shims from the frame.
15. Put a hydraulic jack (25) in position under the bottom pin (24).
16. Remove bottom pin (24) from the bottom pin bearing with the hydraulic jack (25).
17. Remove spacer (26) from the bottom pivot pin bearing.
NOTE: Separation of the frames is not possible until the spacer is removed from the bottom pivot pin bearing.
18. Connect an air supply to the parking brake release valve. Release the parking brake.
19. Move the rear frame back from the front frame with the fork lift truck.
20. Put tooling (B) under the radiator end of the rear frame. Remove the air supply from the parking brake release valve. Remove the fork lift truck.
Connection Of Main Frames
1. Put a fork lift truck in position under the rear of the rear frame. Remove tooling (B) from under the rear frame. Connect an air supply to the parking brake release valve. Release the parking brake.
2. Move the rear frame into position on the front frame with the fork lift truck.
3. Lift or lower the rear frame with the fork lift truck to get the pin bore of the bottom pin in alignment. Use a hydraulic jack (25) to put the bore in alignment from side to side.
4. Put spacer (26) in position in the bottom pin bore bearing and the rear frame. Install plate (21) on the frame to hold the spacer.
NOTE: For easier pin installation, lower the temperature of the pins to -57° C to -68° C (-70° F to -90° F).
5. Put pin (20) in position in the top pin bore. Make sure the bolt holes in the cover for the pin are in alignment with the bolt holes in the frame. Install bolts (28).
NOTE: A bar (27) can be used to put the top pin bore in alignment.
6. Tighten bolts (28) evenly to a torque of 100 ± 14 N·m (75 ± 10 lb.ft.) with the following procedure:
a. Tighten a bolt in the corner of the cover.
b. Tighten the bolt across from the bolt tightened in Step a.
c. Tighten the next two bolts in the other corners of the cover.
7. Put bottom pin (24) in position in the bottom pin bore. Install two long bolts through plate (21) and into the bottom of pin (24) to help keep the holes in the bottom of the pin in alignment with the holes in the plate.
8. Install pin (24). Remove the two long bolts.
9. Remove bolts (23) that hold plate (21) to the frame. Install two bolts (22) 180° apart that hold the plate to the pin. Tighten bolts (22) to a torque of 135 ± 14 N·m (100 ± 10 lb.ft.).
NOTE: Tighten bolts to 80 ± 13 N·m (60 ± 10 lb.ft.) on 120G.
10. Measure the distance between plate (21) and frame (29) with feeler gauge (30) at each bolt hole. Remove bolts (22) and plate (21).
11. Install a thickness of shims same as the minimum distance measured in Step 10 minus 0.25 mm (.010 in.) on plate (21). Put plate (21) and shims in position on the bottom pin. Install all the bolts that hold the plate to the pin and the frame.
12. Remove the air supply from the parking brake release valve.
13. Remove tooling (A) from under the front frame. Remove the fork lift truck from the rear of the rear frame.
14. Put all lines (4) and (7) in their correct locations in clamps (3) and (6) on the front frame and the clamps on the rear frame. Install the nuts on the four clamps that hold the lines. Connect articulation indicator linkage (2) to the rear frame. Install the pin and the cotter pin.
15. Connect the electric wires, starter cable, and air lines to their correct locations on the rear frame.
