2.1 HYDRAULIC SCHEME
The hydraulic system consists essentially of a fluid
tank, hydraulic pump, oil filter, oil cooler (CK22H), HST
(CK22H), priority valve, Joy-stick valve, control valve,
and lift links.
The rear axle and transmission case serve as a com-
mon hydraulic fluid tank and supply fluid to the hydrau-
lic pump (2) through the filter (1) and suction tube.
The hydraulic pump supplies fluid to the system con-
trol valve through the priority valve (3) and the high-
pressure line.
The control valve, when operated, affects raise, neutral,
or lowering action of the lift arms.
