Fastener torques
6.5.1 Single row cover-to-case bolting metal-
to-metal gasketed joints
1) Clean and inspect each stud or bolt, nut, washer,
and the facing on the flanges against which the
nuts will rotate. Look for severe galling, pitting,
etc. If any of the above mentioned items are
damaged beyond repair, replace that item.
2) Lubricate all thread contact areas and nut
facings. There are many suitable lubricants
available on the market today (i.e., Fel-Pro N-
5000, Never-Seize) that can be selected to
provide the necessary low friction for installation
and adequate anti-seize properties for high
temperature applications.
3) Before tightening the studs or bolts, number
each stud or bolt by following the circumferential
numbering order for the appropriate bolt pattern
shown in the following chart (
Figure 6-2)
.
4) Torque the studs or bolts to 30 percent of the
final torque required listed in the
Table 6-1
,
following the sequence printed on the studs or
bolts in
Figure 6-2
. If this sequence is not
