ASSEMBLY OF
KMBD-240C &
KMBD-400C
The assembly procedure is generally the same for all series, but where
there are differences notations will be made.
All vacuum joints, end covers, seal casings and plugs should be sealed
with an RTV Silicone Sealer, Kinseal or equal, unless o-rings have
been provided.
Dowel pins are used to locate end plates, housing and drive end cover
in the proper location relative to each other. Be sure they are in place.
It is recommended that the gear end rotor shaft bearings be purchased
from Tuthill Vacuum Systems, as they are specially ground to locate
the rotors with correct end clearance relative to the gear end plate. Do
not use standard bearings which have not been flush ground
within .001 tolerance. Use factory approved parts only.
