HYDRAULIC UNITS
HST PUMP
Adjustment of Displacement Limiter of the
Remote Hydraulic Control
WARNING
• Be sure to do these adjustments on the level
ground.
• The hydraulic oil and the tank are hot and
under pressure at operating temperature.
• Never adjust the pump immediately after
the engine stops to prevent bodily injuly, be-
cause all the components are hot.
• Do not allow hot oil and components to con-
tact your skin.
• When removing the hydraulic hose, slowly
loosen the hydraulic hose.
• Failure to adjust the displacement limiter
may result in uncontrollable operations of
the machine during traveling.
Improper adjustment of the displacement limiter
may cause track deviation.
By adjusting the displacement limiter, limit the
maximum gradient of the swash plate and control
the discharge volume of the right and left hydraulic
pumps. This will adjust the speeds of the right and
left travel motors to avoid track deviation.
