SEAT BELTS
SERVICING LAP AND SHOULDER
BELTS - ALL MODELS
Before servicing or replacing lap and shoulder belts,
including single loop belt systems, refer to the following
precautionary items:
1. Lap and shoulder belts will be serviced as follows:
a. All belts will be serviced in complete sets.
b. Do not intermix standard and deluxe belts on front
or rear seats.
2. Keep sharp edges and damaging objects away from
belts.
3. Avoid bending or damaging any portion of the belt
buckle or latch plate.
4. Do not bleach or dye belt or strap webbing (clean
with a mild soap solution and water).
5. When installing lap or shoulder belt anchor bolt,
start bolt by hand to assure that bolt is threaded straight.
6. Do not attempt repairs on lap or shoulder belt
retractor mechanisms or lap belt retractor covers. Replace
defective assemblies with new service replacement parts.
7. Do not attempt to remove seat belt retractor cover.
The cover and the long rivet securing the cover to the
retractor are not available as service replacement parts.
LAP BELTS AND SHOULDER BELTS
The shoulder belts and lap belts are attached to the
front seat lap belt latch plate and connected to an inertia
locking retractor installed to the floor or quarter inner panel
above the right and left side of the front seat. The belts
remain unlocked to allow occupants to move freely while
the vehicle is being operated. When the vehicle decelerates
or changes direction abruptly, the belts are locked in
position by a pendulum that causes a locking bar to engage
a cog of the retractor mechanism.
Removal and Installation
Refer to illustrations on following pages and select the
appropriate illustration for removing and installing lap belts
and shoulder belts.
Internal drive thread-forming anchor bolts are used to
secure lap belts to the floor pan. To remove or install
internal drive anchor bolts, use door lock striker and lap belt
anchor bolt removal tool J-23457 or equivalent. Start bolt
by hand to assure that bolt is threaded straight.
