Dinete Seat Belt Bracket Recall Work Instruc􀆟ons The following instruc􀆟ons contain references to Newmar part numbers. For more informa􀆟on, see the atached prints. 1. Extend the slideout containing the dinete. 2. Remove the dinete cushion from the seat facing the front of the coach. 3. Pull open the dinete drawer. 4. Remove the nuts and washers from the seat belt bolts. Set them aside with the seatbelt(s) for reuse later. 5. Mark the orienta􀆟on of the exis􀆟ng seatbelt plate on the botom of the slideout floor. Then push the seat belt bolts down from the top side, tapping lightly if needed. 6. Look at the seat frame just below the side panel, locate the lag screws on the frame, and set them aside for later. 7. Remove the four screws securing the seat frame to the floor. 8. Remove the dinete assembly and set it aside for later. 9. Put plate (167118) on top of the carpet in the corner of the slideout wall and televator cabinet. Using a u􀆟lity knife, carefully cut the carpet around the edge of the bracket. 10. Remove the bracket. Then remove the cut piece of carpet, along with any remaining staples. 11. Put plate (167118) back into the corner against the bare wood floor. 12. Using a #1 drill bit, drill each of the holes in the side lip of the plate (167118) into the televator cabinet and the sidewall. On the side wall, only drill through the first layer of structure tubing (three holes in the wall) in the wall, and on the televator cabinet frame, drill through both sides of the structure tubing (two holes in cabinet frame). 13. Using screws (167282), start fastening the plate (167118) to the televator cabinet first. Then screw it to the sidewall. 14. In the forward two holes in the televator frame, remove the screws, and drill through the floor with a 3/8” drill bit. 15. S􀆟ck carriage bolts (136657) with plates (167208) up from the botom and fasten the plates with screws (149070). 16. Install washers (45016) and locking nuts (31081) on the bolts coming through the televator frame and 􀆟ghten. Do not over􀆟ghten, as it may crush the aluminum tubing. 17. Set the dinete seat back against the wall and televator cabinet. 18. Use four screws (113970) to screw the dinete back into the floor. 19. Fasten the dinete frame with hex self-drill screws (135164) just under the dinete side cushion. 20. With a 3/16” drill bit, drill two holes through the dinete steel frame through the televator cabinet frame and install two hex self-drill screws (135164). 21. Remove the seatbelt bolts and plate under the slideout. Then redrill 3/8” holes through the seat frame/floor for the seat belt (if needed) to realign with the exis􀆟ng holes. 22. (Note: This step may be easiest with an extra set of hands.) One person on the outside of the coach should reinstall the carriage bolts and seatbelt plate (in the same orienta􀆟on when the bolts and plate were removed) up through the floor while another person inside the coach re-installs the seatbelts and washers/nuts, then fully 􀆟ghten with a torque wrench to 78 􀅌. lbs. 23. Above the dinete seat, measure from the televator cabinet to the fascia and subtract ½”. Using that measurement below the seat back, drill a hole through the dinete seat frame into the sidewall. Move back toward the televator cabinet approximately ½” and drill another hole through the dinete frame into sidewall using a 3/16” drill bit. The goal is to have two fasteners hit the aluminum tube at the front wall structure. Install two hex self-drill screws (167281). 24. Make sure all bolts and screws are 􀆟ght, and the seat belt bolts are torqued. Pull up on the seatbelts and route them behind the dinete seat cushion frame. Install the dinete seat cushion, close the drawer, and test the slideout opera􀆟on to ensure no bolts or plates are interfering with the slide.
