TORQUE SPECIFICATIONS
m
WARNING: Mismatched or incorrect
fasteners can result in damage, malfunction
or personal injury. Avoid mixing metric and
inch dimensioned fasteners.
Exceptions to torques are listed in Service Manual, if
necessary.
Prior to installation of any hardware, ensure components
are in near new condition. Bolts and threads must not be
worn or damaged. Threads must not have burrs or nicks
and hardware must be free of rust and corrosion. Clean
hardware with a noncorrosive cleaner.
Do not lubricate fastener threads except with rust
preventative. Rust preventative should be applied by
supplier of component for purposes of shipping and
storage. Other applications for lubricating components
may be specified in Service Manual.
Constant Torque Hose Clamps
Due to extreme temperature changes, hose will heat set.
Heat setting can cause hose clamps to loosen. Loose
hose clamps can result in leaks. Constant torque of hose
clamp helps prevent leaks.
FIG. 33: Constant torque hose clamp is installed
correctly under the following conditions:
• Screw tip (1) extends 6.35 mm (.25 inch) (A) beyond
housing.
• Belleville washers are collapsed nearly flat after
screw (2) is tightened to a torque of 11 Nm (8.1 lbf ft).
