REMOVAL & INSTALLATION
See Figures 1, 2, 3 and 4
All the seat belt systems found on the these trucks are removed and installed in generally the same manner. The system, whether the front seat belt system or the rear seat system, starts at the seat belt retractor, is routed up and through a seat belt bracket. The belt then travels to the seat, where it is attached to the seat belt buckle. The belt is routed through the buckle and then is attached to the vehicle floor. The other belt is fastened to the rear of the seat frame or to the floor, and is routed up through or around (depending on whether the seat is a bench type seat or a bucket type seat) the seat.
The seat belt mounting components (i.e. the retractor, the brackets, the floor attachment) are held in place with large bolts. To remove the system, remove any piece of trim which may be concealing the retractor. Remove the bolts mounting the retractor to the vehicle body. Remove the bolts holding the upper seat belt bracket to the upper body and the bolts holding the seat belt's other end to the floor. Remove the other belt's floor attachment bolt, and either pull the belt our through the seat, or simply remove the belt from the vehicle. If any wires are attached to the seat belt buckle, disconnect and label them.To install:
For the covered buckle type of seat belts, mount the anchor plates on the buckle side and the anchor plates on the center belt together, parallel to the center axis of the vehicle. For the stalk buckle type seat belts, mount the buckle stalks parallel to the center axis of the vehicle. Connect the seat belt warning light wiring to the front harness (left side only). Pass the center belt buckle and tongue through the belt bands of the seat cushion. Install the seat belt without twisting it. Fix the anchor plate for the tongue side of the seat belt to 45° upward from the horizontal line, and install the Emergency Locking Retractor (ELR). Tighten the anchor bolts to 25-39 ft. lbs. (34-53 Nm).
