WARNING: Mismatched or incorrect
fasteners can result in damage, malfunction
or personal injury. Avoid mixing metric
dimensioned fasteners and inch
dimensioned fasteners.
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.
Hardware must be free of rust and corrosion. Clean
hardware with a noncorrosive cleaner.
Do not lubricate fastener threads except for rust
preventive. Rust preventive should be applied by supplier
of component for purposes of shipping and storage. Other
applications for lubricating components may also be
specified in Service Manual.
Constant Torque Hose Clamps
Due to extreme temperature changes, hoses heat set.
Heat setting can cause hose clamps to loosen. Loose
hose clamps can result in leaks. There have been reports
of component failures caused by loosened hose clamps.
Constant torque hose clamp help prevent these failures.
FIG. 32:
Constant torque hose clamps 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).
