Hydraulic System

Troubleshooting

The cause of an improperly functioning hydraulic system
is best diagnosed with the use of proper testing equip-
ment and a thorough understanding of the complete hy-
draulic system.

A hydraulic system with an excessive increase in heat or
noise is a potential failure. Should either of these condi-
tions be noticed, immediately stop the vehicle, turn off
the engine, locate the cause of the trouble and correct
it before allowing the vehicle to be used again. Contin-

ued use of an improperly functioning hydraulic system
could lead to extensive internal component damage.

The charts that follow contain information to assist in
troubleshooting. There may possibly be more than one
cause for a vehicle malfunction.

Refer to the Testing section of this Chapter for precau-
tions and specific hydraulic test procedures.
