Charge Relief Pressure
CAUTION
• When checking, park the tractor on flat ground, apply the
parking brake.
1. Remove the plug (M14, Pitch 1.5 mm) (1) from the front cover,
then install the adaptor, cable and pressure gauge.
2. Set the range gear shift lever to Neutral position.
3. Start the engine and run it at the maximum speed.
4. Read the pressure gauge to measure the charge relief pressure.
5. If the measurement is not within the factory specifications, check
the charge relief valve and related hydraulic components.

High Relief Pressure
CAUTION
• When checking, part the tractor on flat ground, apply the
parking brake.
1. Remove the hexagon socket head plug (3/4-16 UNF-2A) from P1
(1) or P2 (2), then install the adaptor, cable and pressure gauge.
2. Start the engine and run it at maximum speed.
3. Set the range gear shift lever to High position.
4. Depress the speed control pedal to forward or reverse, and read
the pressure gauge to measure the high relief pressure.
5. If the measurement is not same as factory specification, check
the high pressure relief valve and related hydraulic components.
Factory spec. (Oil
High relief pressure temperature at 50 °C,
122 °F)

IMPORTANT
• Measure quickly so that the high pressure relief valve may
not be in operation more than 10 seconds.
NOTE
• When reinstall the hexagon socket head plug, take care not
to damage the O-ring.
