7.5.3 Vacuum Pump Assembly Instructions
1. Fit bearing to rotor (DE). Use blocks to
raise rotor and fit the inside of the other
bearing. (NDE)
2. Fit the spacer and 0.003” shim into the bore
of the NDE cover plate.
3. Place the rotor into the bore and spin.
Check the gap between the rotor and plate
using a feeler gauge.
4. Fit M10 grub screw to the base to plug hole.
Place rotor inside stator.
5. Adjust plate so that rotor is not rubbing
against stator wall. Fit M10 x 25
6. Fit 6 M10 x 40 studs to stator on NDE and
fit dowel and O-Rings. Fit stator and non-
drive end plate together using M10 nuts
and flat washers.
7. Oil the vanes and slide them into the stator
on the drive end.
8. Fit the lip seal into the DE plate. Note that
the lip seal is to be fitted with the lip and
spring facing outward to prevent ingress of
dirt and air.
9. Place the wave spring washer and the rest
of the bearing into the bore of the plate.
10. Fit the plate to the stator, ensuring that the
dowel is located.
