TORQUE SPECIFICATIONS

WARNING: Mismatched or incorrect
fasteners can result in damage or
malfunction, or personal injury. Take care to
avoid mixing metric dimensioned fasteners
and inch dimensioned fasteners.
Exceptions to these torques are given in the Service
Manual if necessary.
Prior to installation of any hardware, ensure that
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 the hardware with a noncorrosive
cleaner.
Do not lubricate the fastener threads except for the rust
preventive. The rust preventive should be applied by the
supplier of that component for purposes of shipping and
storage. Other applications for lubricating components
may also be specified in the Service Manual.
Constant Torque Hose Clamps
Due to extreme temperature changes, the hose will heat
set. Heat setting can cause hose clamps to loosen. Loose
hose clamps can result in leaks. There have been reports
of component failures that have been caused by hose
clamps that have loosened. The constant torque hose
clamp will help prevent these failures.
FIG. 9: The constant torque hose clamp is installed
correctly under the following conditions:
• Screw tip (1) extends 6.35 mm (.25 inch) (A) beyond
the housing.
• The belleville washers are collapsed nearly flat after
screw (2) is tightened to a torque of 11 Nm (8.1 lb/ft).
