7. Mounting hardware should be evaluated for corro-
sion, and for tightness of bolts and nuts.
8. Check web in areas exposed to ultraviolet rays from
the sun. If the color of the web in these areas is gray
to light brown, the physical strength of the web may
have deteriorated due to exposure to the sun's ultravi-
olet rays. Replace the system.
Once the need for replacement of the seat belt has been
determined, be certain it is only replaced with an autho-
rized PACCAR Parts replacement seat belt.
If the inspection indicates that any part of the seat belt
system requires replacement, the entire system must be
replaced. An installation guide is attached to every
replacement belt. Utilize the proper guide for your type of
seat, and follow the instructions very closely. It is vitally
important that all components be reinstalled in the same
position as the original components that were removed
and that the fasteners be torqued to specification. This will
maintain the design integrity of the mounting points for the
seat belt assembly. Contact your Authorized Peterbilt
Dealer if you have any questions concerning seat belt
replacement.
Windshield Wipers/Washer
Check wiper blades annually or every 60,000 miles
(96,000 km). Anco 18-inch (450mm) wiper blades are rec-
ommended.
The windshield washer tank is located inside the engine
compartment below the radiator expansion tank. See
“
Washer Reservoir” on page 234. Check the windshield
washing fluid level weekly. If necessary, fill to top.
CAUTION: If the electric pump is operated for
a long period (more than 15 seconds) with a
dry reservoir, the pump rotor may be dam-
aged.
Clean all inside and outside windows regularly. Use an
alcohol-based cleaning solution and wipe dry with either a
lint-free or a chamois cloth. Avoid running the wiper
blades over a dry windshield to prevent scratching the
glass. Spray on washer fluid first. A scratched windshield
will reduce visibility.
