4-4 HYDRAULIC SYSTEM
4-4.1 General
a. Check the oil level of the tractor wet kit or
hydraulic engine power hydraulic tank weekly,
or after any leakage. See Table 4-1 for proper
hydraulic oil. Check the hydraulic oil level with
hydraulic cylinders in the retracted position
and the hydraulic pump disengaged.
b. Overfilling can cause hydraulic fluid over-
flow during operation.
c. Check the lubricating oil level in the engine
of the hydraulic engine power option.
d. Inspect hydraulic hoses for chafing or dam-
age. Replace if jacket or braid of hose is dam-
aged.
e. Replace hydraulic engine power filter as
specified in Table 4-2.
4-5 ELECTRICAL SYSTEM
4-5.1 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.
4-5.2 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.
4-5.3 Corroded terminals must have the corro-
sion removed, source of corrosion neutral-
ized and the terminals resealed, protected,
and insulated.
4-5.4 Fuse or circuit breaker burn-out or
blow-out usually indicates an electrical
short-circuit, although a fuse can occasion-
ally 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.
4-5.5 A light that repeatedly burns-out usually
indicates a loose connection, poor system
ground, or a malfunctioning voltage regula-
tor. Locate the source of the problem and re-
pair. System grounds must be grounded to
bare metal surfaces. Paint, grease, wax, and
other coatings act as insulators. Replace-
ment lamps must be equivalent to the factory
installed lamp.
