Assembly
1. Assemble the variable displacement pump in
reverse order.
2. Measurement of the taper roller bearing pretension
(see adjustment figure).
NOTE: There is a correct connection of the piston rod and
swash plate.
3. Pumps clockwise driven must have a position of the
valve plate 4° out of center in the same direction
decentered like drive direction.
NOTE: Spare parts exist as clockwise and counter-clock-
wise valve plates.
4. Pumps anti-clockwise driven must have a position of
the valve plate 4° decentered in counter-clockwise
position.
5. Assembly of the port plate and pump housing:
NOTE: The correct position of the drilling that connects high
pressure to the control valve. Check control valve
drilling position at the pump housing and fit together.
