5.1 SWING BEARING

Swing Bearing Attach Bolts Check

This check must be performed after the first 50 hours of
machine operation and every 500 hours of machine oper-
ation thereafter. If during this check, bolts are found miss-
ing or loose, replace missing or loosen bolts (use
Loctite®270 on bolts installed in threaded holes through
turntable base plate).
Outer bearing race is attached to the chassis plate.
Inner bearing race is attached to the turntable base plate.
1. Place the machine on a flat and level surface. Fully
lower the mast and the jib. Remove chassis hoods
and chassis side shields. Remove bearing teeth cov-
ers.
2. Using a suitable
attached to both lifting rings of mast section #1, lift
and place the machine on blocks of a minimum
height of 300mm (12") and capable of supporting
the weight of the work platform. Position blocks in
such a way that the swing bearing attach bolts to the
chassis remain accessible and that the machine
remain stable on blocks when the structure will be
swung.

3. Check outer race attach screws and nuts in
sequence for correct torque condition: torque value
117 Nm (86 ft lbs). If needed, attach screws are
accessible through an access hole (1) in the turnta-
ble base plate: rotate superstructure using the
ground controls (or manual swinging devices) to
gain access to each screw.
4. Check inner race attach screws and nuts in
sequence for correct torque condition: torque value
117 Nm (86 ft lbs). Attach screws are accessible
through an access hole (2) in the chassis base plate:
rotate superstructure using the ground controls (or

Figure 5-3. Swing Bearing Race Lubrication
1. From ground control station, raise the mast to gain
access to the turntable base plate.
2. Locate the access hole (1) on the turntable plate.
3. Swing the structure to the right to gain access to the
first grease fitting (2).
4. Lubricate using a grease gun.
5. Swing the structure 180° to the left to gain access to
the second grease fitting and lubricate.
