REASSEMBLY OF RELIEF VALVE
ASSEMBLY, ETC.
1. Install relief valve assembly (45) (hex hole
size 14 mm) to cover (19) with torque of
137 Nm. Install check (36) and spring (37)
to cover (19) and tighten cap (38) (hex
hole size) to cover (19) with torque of 137
Nm. Tighten bypass valve assembly (30)
(hex hole size 10 mm) to cover (19) with
torque of 78 Nm. Tighten time relay valve
(39) to housing with torque of 12 Nm by
means of hex socket bolt (40) (hex hole
size 5 mm).
NOTE: Install relief valve assembly
(45), cap (38), spring (37),
check (36), bypass valve
assembly (30), and time relay
valve (39) to the original
position which was
disassembled before.
CONFIRMING OF REASSEMBLY
1. Open inlet and outlet port of motor, apply
pilot pressure of 3.9 - 4.9 Mpa to brake
release port, and then check the turning of
output shaft with torque of about 30 - 40
Nm over one revolution smoothly. If it does
not turn, readjust it by disassembling
because it is improperly reassembled. At
this time open drain port also.
NOTE: After reassembling hydraulic
motor, check the setting
pressure of relief valve (45).
INSTALLATION
Piping
Dimensions for piping is already decided in outside drawing. Piping is to be hose or steel part. Also when
piping, detach cap seal of rubber of port part. Because drain pipe is decreased pressure in motor case,
uses large diameter pipe. Also when connecting return pipe other components, return oil is squirted out
suddenly, abnormal back pressure of pressure in motor case should be below 0.3 MPa.
