Checking the Frame Fastener Torque
Because of "bedding in" (or seating), the frame fasteners must be torqued at the recommended intervals. These intervals apply to new vehicles, and to frame fasteners that have been removed and installed again.
Caution: Make sure frame fasteners are properly tightened. Continued vehicle operation with loose fasteners could result in bracket or frame damage.
Typical frame fastener applications include suspension and fuel tank brackets, exhaust and engine supports, and frame crossmembers and gussets.
Note: This operation is not intended to be a bolt-by-bolt check of the entire chassis. Do a hand check of the typical frame fasteners. If any fasteners are found loose, tighten them to the correct torque value.
See of the Shuttle Bus Chassis Workshop Manual for additional information on fasteners and torque values, or take the vehicle to an authorized Freightliner dealer.
