IMPORTANT
• When the neutral position of the machine is checked, it is
advisable to divide the checking procedure as follows:
First check the HST unit alone, and then connect the HST
unit to the link for checking.
1. Remove the cargo bed.
2. Remove the hex. socket head plug from P1 port (5) and P2 port
(4).
3. Install the HST adaptor and low pressure gauge in P1 port and
P2 port.
4. Remove the HST control rod (1) from the HST control lever (3)
to make situation that HST control lever move freely.
5. Set the 4WD lever to 2WD position.
6. Start the engine and shift the range gear shift lever in L position
for 5 seconds to make sure that the HST is in neutral position.
7. At this time, check both P1 port (5) and P2 port (4) pressure if
the wheel rotates.
8. If the measurement is not within the factory specification, adjust
with hex. socket head screw (8).
(Adjusting procedure)
• Adjust to loosen the lock nut (6) on a right side of servo piston
and for the adjustment hex. socket head screw (8) to make both
P1 port (5) and P2 port (4) pressure equal while seeing the
pressure gauge.
• Retighten the lock nut (6) securely.
(Reference)
• The pressure of P2 port (4) (dynamic brake) rises when turning
the clockwise.
• The pressure P1 port (5) (traveling side) rises when turning the
counterclockwise
9. Reinstall the HST control rod (1) to HST control lever (3) after
you make sure neutrality in the HST unit.
10. Adjust the rod length and much a neutral position if the wheel
rotates after is stalling the HST control rod (1).
