4. Install bearing hub (64) on bearing post (61).
5. Install lockwasher (65) on bearing post (61).
• The following torque procedure must be followed to ensure
that spanner nut torque is correct, bearings have been seated,
and nut will not lose torque. Failure to follow these
instructions will decrease performance of the pivot and may
cause damage to the jib boom.
6. Tighten spanner nut (66) to 200 ft.-lbs. (271 Nm)
7. Rotate pivot assembly left and right to seat bearings.
8. Torque spanner nut to 200 ft.-lbs. (271 Nm)
9. Rotate pivot assembly left and right to seat bearings.
10. Torque spanner nut to 200 ft.-lbs. (271 Nm)
11. Rotate nut clockwise until a lockwasher tang is aligned with a
slot on spanner nut. Bend tang into slot.
12. Install pivot assembly on column.
13. Torque pivot mounting bolts to 50 ft.-lbs. (68 Nm)
• Ensure the tang on the lockwasher in the upper housing
engages a slot on the pivot pin.

lower housing assembly will not swivel.
Air System Installation
Refer to Dwg. MHP2051 on page 32.
1.
Assemble swivel compression fittings (148) to pre-coiled
tubing (149).
2. Install hose fittings (151) to each end of the rubber hose
(152).
3. Install adapter-fitting (153) to one end of the rubber hose
(152).
4. Connect adapter (150) to one end of the pre-coiled tube
(149).
5. Align bracket (83) with each end of the jib boom.
6. Determine which side of the bracket to install the
filter/regulator (55). The regulator should be installed at the

bracket.
7. Install filter/regulator (55) to bracket (83).
8. Install elbow fitting (147) to bracket (83).
9. Install eye bolt and nut assemblies (94) to brackets (83). The
eye portion of the bolts will face each other when the
brackets are installed.
10. Install thimble (93) to eyebolt (94).
11. Thread cable (91) through the center of the pre-coiled tube
(149).
12. Thread cable (91) through the eyebolt (94) and thimble (93).
13. Install clamps (92) to cable (91). Do not tighten, rather snug
the bolts so cable will not slip through clamp.
14. Install brackets (83) to top of jib boom with the eyebolts
toward each other, using bolts (80), washers (82),
lockwashers (81) and plates (84).
15. Tighten clamps (92) at one end of cable.
16. At opposite end of cable thread excess cable through clamps
increasing tension until cable supports the weight of the pre-
coiled tube.
17. Tighten clamp (92).
18. Connect adapter-fitting (152) to lifting unit inlet.
19. Rotate shut off valve to the closed position.
20. Connect plant air supply or column air supply to regulator
(55) inlet.
21. Rotate shut valve to the open position.
22. Adjust regulator to 100 psi (6.9 bar).
Electrification System Installation
Refer to Dwg. MHP2050 on page 34.
1.
Align bracket (83) with each end of the jib boom.
2. Determine which side of the bracket to install the anchor
bracket (96). The anchor bracket must be installed closest to
the pivot or wall end.
3. Install eye bolt and nut assemblies (94) to brackets (83). The
