SR 4 GENERATOR
DISASSEMBLY AND ASSEMBLY
Electric Sets Without Supports at the Flywheel
Housing
GENERATOR SET
11. Bolts. 12. Base.
a.
If base (12) of the electric set is fastened to a
foundation, loosen all base-to-foundation bolts.
Loosen all bolts (11) that fasten the engine
supports to base (12).
b.
Check to be sure there is clearance between the
bolts and the bolt holes in the base, engine
supports and generator supports at all locations.
c.
Check the clearance between the base and its
foundation at all mounting locations. Use shims
as necessary to prevent deflection of the base
as the base-to-foundation bolts are tightened.
When there is no deflection in the base tighten
all base-to-foundation bolts to their final torque.
CHECK CLEARANCE
10. Support.
d.
Check the clearance between the base and the
engine and generator supports at all four
location
(11). Be sure to check the clearance over the entire
length of the support. This is especially important on
generators with long supports (10), since some surfaces
may not be square or parallel. Use shims as necessary
to prevent deflection of the supports as the bolts are
tightened. After all the necessary shims have been
installed, tighten all mounting bolts to their final torque.

a.
If base (12) of the electric set is ,fastened to a
foundation, loosen all base-to-foundation bolts.
Loosen all bolts that fasten the engine and
generator supports to the base.
b.
Check to be sure there is clearance between the
bolts and the bolt holes in the base, engine
supports and generator supports at all locations.
c.
Check the clearance between the base and its
foundation at all mounting locations. Use shims
as necessary to prevent deflection of the base
as the base-to-foundation bolts are tightened.
When there is no deflection in the base, tighten
all base-to-foundation bolts to their final torque.
d.
Loosen all bolts (7) that fasten the generator to
the flywheel housing. Tighten every other bolt to
its final torque. Check the clearance between
the base and the engine and generator supports
at all six locations. Be sure to check the
