Checking High Pressure Relief Valve Pressure (Traveling Side)
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
might be damaged, and the plug not be loosened.
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.
1. Remove the cargo bed.
2. Remove the hex. socket head plug from P1 port (2). (P1 is for
traveling side.)
3. Install the HST adaptor and high pressure gauge to P1 port (2).
4. Check to see that parking brake is applied.
5. Remove the unload linkage (1).
6. Set the 4WD lever to 2WD position.
7. Start the engine.
8. Place the range gear shift lever in H position.
9. Depress the speed control pedal, and measure the check and
high pressure relief valve pressure. (Engine speed is set by
using the tachometer.)
10. If the measurement is not within the operating pressure, replace
the check and high pressure relief valve assembly with new
one. (See page 2-S55.)
