f. Following the torque sequence diagram shown
i n F i g u r e 3 - 2 6 . , S w i n g B e a r i n g To r qu e
Sequence, tighten the bolts to an initial torque of
140 ft. lbs. (190 Nm). Then following the same
sequence, tighten to a final torque of 190 ft. lbs.
(260 Nm).
g. Remove lifting equipment from bearing.
h. Use suitable lifting equipment to carefully posi-
tion the turntable assembly above the machine
frame.
i. Carefully lower the turntable onto the swing
bearing. Ensure that the scribed line of the inner
race of the bearing aligns with the scribed mark
on the turntable. If a new swing bearing is used,
ensure that the filler plug fitting is at 90 degrees
from the fore and aft centerline of the turntable.
j. Apply a light coating of threadlocker JLG P/N
0100019 to the new bearing bolts and install
through the turntable and inner race of bearing.
k. Following the torque sequence shown in Figure
3-26., Swing Bearing Torque Sequence, tighten
the bolts to an initial torque of 150 ft. lbs. (200
Nm). Then following the same sequence, tighten
the bolts to 210 ft. lbs (285 Nm).
l. Remove the lifting equipment.
m. Route hydraulic lines through center of turntable
and frame and connect as tagged prior to
removal.
n. Using all applicable safety precautions, activate
the hydraulic system and functionally check
swing system for proper and safe operation.
