TRAILER MAINTENANCE TIRES/WHEELS/LUG NUTS Suspension Tires and wheels are a very important and critical The leaf suspension springs and associated components components of the trailer. When specifying or replacing the (Figure 60) should be visually inspected every 6,000 miles trailer wheels it is important the wheels, tires, and axle are for signs of excessive wear, elongation of bolt holes, and properly matched.
TRAILER MAINTENANCE Lug Nut Torque Requirements It is extremely important to apply and maintain proper wheel mounting torque on the trailer. Be sure to use only the fasteners matched to the cone angle of the wheel. Proper procedure for attachment of the wheels is as follows: 1.
TROUBLESHOOTING (GENERATOR) Practically all breakdowns can be prevented by proper handling and maintenance inspections, but in the event of a breakdown, use Table 19 shown below for diagnosis of the Generator. If the problem cannot be remedied, consult our company’s business offi ce or service plant. Table 19.
TROUBLESHOOTING (DIAGNOSTIC LAMP) The engine controller of this generator diagnoses problems that arise from the engine control system and the engine itself. Press the diagnostic button (Figure 66) on the diagnostic panel to determine if an engine malfunction has occurred. Figure 66.
