TIGHTENING PROCEDURE
1 Refer to the Torque Data Chart to determine the proper torque value to apply to the size of
capscrew used.
2 Follow the tightening sequence shown in the diagram. Note that the quantity of capscrews
may differ from the diagram, but the sequence must follow the criss-cross pattern as shown in
the diagram.
3 Torque all capscrews to approximately 40% of the specified torque value, by following the
sequence.
(EXAMPLE: .40 x 265 FT-LB = 106 FT-LB)
(EXAMPLE-METRIC: .40 x 36 KG-M = 14.4 KG-M)
4 Repeat Step 3, but torquing all capscrews to 75% of the specified torque value. Continue to
follow the tightening sequence.
(EXAMPLE: .75 x 265 FT-LB = 199 FT-LB)
(EXAMPLE-METRIC: .75 x 36 KG-M = 27 KG-M)
5 Using the proper sequence, torque all capscrews to the listed torque value as determined
from the Torque Data Chart.
Turntable Bearing Inspection
Turntable bearings may experience wear. One of the following conditions may indicate turntable
bearing wear:
1 Metal particles present in the bearing lubricant.
2 Increased drive power required to rotate the crane.
3 Noise emitting from the bearing during rotation.
4 Rough rotation.
5 Uneven or excessive wear between the pinion gear and turntable gear.
If one or more of the above conditions exists, further inspection may be required. Contact IMT
for assistance.
