6. Check that the axles, pump and motor are
parallel and the pulleys are true. The belts
should not run on an angle into the pulleys.
The inclination of the pump can be changed
with screw (3), fi g C.
7. The bearings of the turbopump should be
lubricated with Dustcontr ol bearing grease for
turbopumps, Part No. 9928.

Lubrication
- The front bearing should be lubricated using
the grease nipple (4), fi g (C). Press grease in
until it comes out along the axle.
- The back bearing should be lubricated by re-
moving the fi nned bearing cover plate (5) and
checking the condition of the grease. Fill the
cavity 2/3 full with new grease.
- Exchange the O-ring, Part No. 4789 and re-
place the bearing cover plate.
F
- Remove the damper cover (1) and measure
distance A.
- Loosen the locking nut (3) and adjust the
spring tension by turning the spring plate (4).
The compression of the spring (2) determines
the opening pressure. Changing the distance
A by 1.5 mm will give a corresponding change
in pressure of 1 kPa.
- Remount the valve after adjustment and test
the pressure.
9. Inspect all cables and connections, repair if
neccessary.
10. Remount the protective panels, power up the
pump and give it a test run.
