INSTRUCTIONS FOR THE ASSEMBLING OF GENERATORS WITH MD35 FORM
A bad alignment may cause vibrations and bearing damages. It is advisable
to verify the compatibility of the engine / generator torsional characteristics
(by the customer).
The necessary data for this verification are available on the concerning docu-
mentation.
For the coupling of a generator with MD35 form, proceed as follows:
a) according to the type of the coupling, verify the correct placement of the
discs (dimension "L") (table 24 pag. 43); if necessary restore the "L" dimen-
sion moving gently and axially the rotor. In the right position the clearance
of rear bearing should be from 0.5 to 2 mm.
b) (For series 28) through one of the two lateral openings, and by manually
rotating the rotor, detect the relevant clamp screw on the fan hub
c) (For series 28) let the fan be free to rotate by slackening the M8 screw by
means of an hexagonal wrench, possibly having an articulated head
d) (For series 28) position one of the disk holes near the upper part of one
of the side openings and place the slit that is on one of the fan blades, in
the same position
e) move the generator close to the coupling engine
f) align one of the flywheel disk fastening holes with the holes of the pre-
viously positioned disks (point "d")
