MAINTENANCE AND LUBRICATION
451
Frame rail and cross member nuts and bolts should be checked
periodically and tightened to the specified torque if necessary.
Frame Alterations
Under no circumstances can the frame be cut and an extension piece
added to increase the wheelbase. The only alteration allowed is wheel
base shortening, where the only change in the frame rail is a new hole
pattern drilled for the new location of the rear suspension.
Welding in Vehicle
Use only electric welders due to the coating on
material used to build cabs. Oxygen and Acetylene
welding will not bond properly due to coating.
Do not weld anywhere in or on the vehicle before disconnecting
batteries, all electronic control units (ECUs) and instrument cluster.
DO NOT use oxy/acetylene welding to repair cab panels.
