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.
