1. GENERAL

1.1 LINES

Supply line
The supply line connects the reservoir to the

steering pump and consists partly of a thick,

flexible rubber hose and, within the engine

enclosure, it is made of a steel pipe.

The hose is attached to the reservoir with a hose

clamp.

As the steering pump is of the non-regenerative

type, the reservoir should be fitted at a certain

height over the steering pump.

The length of the supply line also influences the

steering pump operation.

If the reservoir is moved, thus making the supply

line longer, the reservoir should also be fitted

higher.

Delivery line
The delivery line connects the steering pump to

the steering box and consists partly of a rubber

hose with an internal, braided, steel casing and

partly of a steel pipe. The admissible pressure is

marked on the line.

The line is connected to the steering pump and

the steering box using a union nut connection.

Return line
The return line connects the steering box to the

reservoir and consists partly of a steel pipe and

partly of a flexible rubber hose with a textile

sheath.

The line is connected to the steering box with a

union nut connection and to the reservoir with a

hose clamp.

1.2 OPERATION OF THE RESERVOIR

General
The reservoir can be made of plastic or steel.

The reservoir is equipped with a filter element,

which filters the return oil.

The filter is not fitted into the supply line as this

would increase the filter resistance of the filter

element and, as a result, the reservoir would

have to be very large.

When working on the steering gear,

prevent dirt from entering the

reservoir or the lines. The steering

oil is drawn in unfiltered, allowing

impurities to enter into the steering

gear.

A by-pass valve is fitted under the filter. If the

resistance in the filter is excessive, e.g. because

of cold oil or a polluted filter, the by-pass valve

opens. Part of the oil will flow into the reservoir

without being filtered.

A dipstick is located at the top of the reservoir with

a minimum and maximum oil level mark.

A small bleeding hole is fitted in the rubber

dipstick cap. This hole should never be blocked,

as the return pressure would become too high.
