Personal injury can result from hydraulic oil pressure and
hot oil.
Hydraulic oil pressure can remain in the hydraulic system
after the engine has been stopped. Serious injury can be
caused if this pressure is not released before any service
is done on the hydraulic system.
Make sure all of the attachments have been lowered, oil is
cool before removing any components or lines. Remove
the oil filler cap only when the engine is stopped, and the
filler cap is cool enough to touch with your bare hand.
NOTICE
Care must be taken to ensure that fluids are contained

Pump Flow Test
(1) Gear Pump. (2) Line.
3.
Assemble adapters to the flowmeter. Install the
flowmeter between the gear pump and the line (2).
4.
Start the engine and run the engine at high idle at 2350
50 RPM until the hydraulic oil temperature is at a
minimum of 38C (100F).
5.
Record the flow rate at the flowmeter. The flow rate
should be 53 1.2 L/min (14 0.3 US gpm).
6.
If the flow rate is not correct, refer to Testing and
Adjusting, "Steering System Troubleshooting".
7.
If the flow rate is correct, remove tooling and reconnect
lines.

Escaping fluid under pressure, even a pinhole size leak,
can penetrate body tissue, causing serious injury, and
possible death. If fluid is injected into your skin, it must
be treated immediately by a doctor familiar with this type
of injury.
Always use a board or cardboard when checking for a
leak.
