Cautionary Notes
ensuring that the drive pin slot at back of
Spring Assembly slides into place over
the drive pin.

Fit dynamic (rotating) part (Silicon
Carbide Ring) of the mechanical seal into
place against the spring assembly. There
will be resistance from the dynamic ring
o-ring. Lightly oil o-ring. Push dynamic
ring into place using thumbs. Note there
are 2 tabs which locate dynamic ring in
spring assembly.
Take care not to damage the seal
face. Use protective card wrapped
around crankshaft as described
above.

Fit the non-rotating part of the seal into
gland housing.
As above, there will be resistance
from the static ring o-ring. Lightly
oil o-ring. Push static ring into
place using thumbs. Drive slot at
back of static ring must locate with
drive pin.

Fit the gland housing complete with seal.
Ensure that the faces of the
mechanical seal parts are dry ie.
free of oil.
5
Remove protective paper / card from
shaft.
6
Tighten gland plate screws.

Slide the coupling hub into place on shaft
8
As detailed above, it is most important to
have correct distance between the motor
hub and the compressor hub.
9
Lightly clamp the hub to the shaft by
tightening the cap screws on the hub.
This will stop the hub moving when
the flange is fitted.
10
Fit Coupling Flange and tighten cap
screws.
11
Check that distance between coupling hub
“flanges” is correct.
The distance must be 117mm.
12
Ensure that drive coupling hub locking
bolts are tightened to correct torque.
