Hydraulic Pump (cont’d)
Assembly
Before assembling:
a Thoroughly clean all components with clean hydraulic oil
and dry with compressed air.
b Apply clean hydraulic oil to all sliding surfaces, bearings,
etc.
1 If previously removed from pump casing 5, install tilting
pin 29 and servo piston 28. Use a protector to prevent
damage to the tilting pin head and feedback pin.
2 Take care to align the flange match marks and then fit
swash plate support 18 to pump casing 5 by gently
tapping it with a plastic hammer.
3 Place the pump casing on the workbench with its
regulator mounting face downwards. Attach swash plate
tilting bush 34 to tilting pin 29. Smear the sliding
surfaces of swash plate support 18 and swash plate 20
with grease. Install the swash plate against the support
and manually check that the swash plate slides
smoothly.
