Charge Relief Pressure
A CAUTION
• When checking, park the
tractor
on
flat
ground,
and
apply
the
parking
brake.
1.
Remove the plug
(R
1/4) (1) from the front cover, then install the
adaptor (R
1/4) 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 .
• NOTE
• When reinstalling the hexagon
socket
head plug,
apply
liquid
lock
(Three
Bond
1324
or
its
equivalent)
to
the
plug.

A CAUTION
• When checking,
park
the
tractor
on
flat
ground,
and
apply
the

brake.
1.
Remove the hexagon socket head plug (R 1/4) from 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 "Hi" position.
4.
Depress the speed control pedal to "Forward", 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.
