Checking Charge Relief Pressure
CAUTION
• If it is necessary to run engine in an enclosed area, use a
gas tight exhaust pipe extension to remove the fumes.
• Always try to work in a well-ventilated area.
• When checking, park the machine on flat ground, and apply
the parking brake.
• Work by two people when you measure pressure.
• Note that the allen wrench does not come off firmly
because the plug is not loose hard. Otherwise, the plug (1)
might be damaged, and the plug not be loosened.
1. Remove the hex. socket head plug (G1/4) from P3 port (1).
NOTE
• The hex. socket plug is securely tightened. Therefore, it is
very important to use a proper-sized allen wrench and fit it
securely onto the plug. Do not give a shock but put your
weight on the plug slowly, paying attention not to damage
its hex. socket section. If the allen wrench is fitted on the
plug at a slant or an improper-sized allen wrench is used to
loose the plug, the hex. socket section will be damaged and
you won't be able to loose the plug.
2. Install the HST adaptor and high pressure gauge to P3 port (1).
3. Place the range gear shift lever in neutral.
4. Set the 4WD lever to 2WD position.
5. Start the engine.
6. Measure the charge pressure.
7. If the measurement is not within the factory specification, check
the charge relief valve. (See page 2-S37.)
(When reassembling)
• Take care not to damage O-ring on plug.
