Hydraulic Testing

Note: Cleanliness is a key factor in a successful

repair of any hydraulic system. Thoroughly

clean all exposed surfaces. As with any pre-

cision equipment, all parts must be kept free

of foreign material and chemicals. Protect all

exposed sealing areas and open cavities from

damage and foreign material.

The following procedure is performed on the left wheel

motor hydraulic hoses. It can also be performed from

several other locations on the machine.

When using a Bi-Directional Flow Test Kit, determining

directional ﬂ ow is not necessary. The ﬂ ow meter may

be connected in either direction into the forward and

reverse high pressure system lines.

Caution: Ensure all ﬁ ttings and hoses are attached

securely. This test is performed on the machine’s

high pressure system. Failure to comply could result

in serious injury.
