Hydraulic system
Dismantling the hydraulic pump
It is assumed that the hydraulic pump is only dismantled by staff who understand its inter-
nal construction.
Notice!
The seals and O-rings are probably damaged during dismantling and are therefore
unusable. Ensure that spare parts are ready for installation.
☞
Drain the oil, clean the pump and place on a clean rubber mat on a work bench
☞
Unscrew the hexagon socket screws (3 x) and remove the pilot oil supply unit
☞
Unscrew the hexagon head screws (2 x) and remove the gear pump and coupling with
the ring
➥
The coupling and ring are located either on the gear pump or variable displacement
pump
☞
Mark or measure the setting of the set screw and note
➥
Makes it easier to restore the correct pump setting
☞
Slacken the locknut and unscrew the set screw with an Allen key
☞
Unscrew the hexagon socket screws (5 x) and separate the pump housing
➥
The housing can be separated more easily by tapping the housing with the inside
spring lightly by means of a rubber hammer
☞
Remove the intermediate seal
