MAINTENANCE AND LUBRICATION
Figure 4-4: Model 835D Flip Axle Wiring Diagram
Electrical System
1.
Maintenance of the electrical system consists of
inspection and minor servicing. Any wire, connection
or electrical component showing signs of corrosion,
wear, breakage or unraveling must be repaired or
replaced.
(See Figures 4-3 and 4-4 for electrical
wiring diagram)
2.
Frayed or unraveling wire must have the defective
section removed and replaced with wire of the same
color and gauge. Seal all connections and insulate.
3.
Corroded terminals must have the corrosion
removed, source of corrosion neutralized and the
terminals resealed, protected, and insulated.
4.
Fuse or circuit breaker burn-out or blow-out usually
indicates an electrical short-circuit, although a fuse
can occasionally fail from vibration. Insert a second
fuse or reset the breaker. If this fuse immediately
burns out or the breaker trips, locate the cause of the
electrical short and repair.
5.
A light that repeatedly burns-out usually indicates a
loose connection, poor system ground, or a
malfunctioning voltage regulator. Locate the source
of the problem and repair. System grounds must be
grounded to bare metal surfaces. Paint, grease, wax,
and other coatings act as insulators. Replacement
lamps must be equivalent to the factory installed
lamp.
Suspension Maintenance
for Tandem Axle and Tandem
Axle w/ Flip Axle Air Ride Suspension drawings.
1.
Physically check all nuts, bolts, and air line fittings for
proper torque (see torque chart below).
* Air Spring Connections Only.
** First number listed is torque required if bolt head
designated with Neway; Second number listed is torque
required if bolt head designated with Holland Neway.
2.
Check all other suspension components for any sign
of damage, looseness, wear or cracks.
3.
With trailer on level surface and air pressure in
excess of 65 psi, all air springs should be of equal
firmness. The height control valve on right side of
front axle controls all air springs on tandem axle
suspensions.
4.
The height control valve on right side of center axle
controls ride height for all air springs on triple axle
suspension.
