Lubrication
Before installing the turntable bearing bolts, lubricate the
following with “Never-Seez” (MCC No. 361010) or an
equivalent anti-seizing lubricant:
• Threads of each bolt
• Underside of head of each bolt
• Both sides of each washer
Torque Values
Torque each turntable bearing bolt to 2,600 ft-lb (3 525 Nm).
When new bolts are installed, torque the bolts in two steps:
• FIRST to 1,000 ft-lb (1 356 Nm)
• SECOND to 2,600 ft-lb (3 525 Nm)
Torque Sequence
Torque the bolts (three at a time) in the numbered sequence
given in Figure 8-1
(one ring at a time).

INITIAL OPERATION: torque all bolts to the specified value
after the first 50 hours of operation.
YEARLY or every 2,000 hours of operation (whichever
comes first): torque all bolts to the specified value.
Bolt Replacement
If at the yearly inspection interval, one or more bolts are
found to be torqued to less than 2,080 ft-lb (2 820 Nm),
replace each loose bolt and washer. Also replace the bolt
and washer on each side of each loose bolt.
If at the yearly inspection interval 17 or more bolts in either
ring are found to be torqued to less than 2,080 ft-lb (2 820
Nm), replace all of the bolts and washers for the
corresponding ring.
Replace all bolts and washers each time a new turntable
bearing is installed.
