3) Generator Assembly Installation.
Installation of a generator assembly is essentially a reversal of the procedure for removal of the generator
assembly: the re-mounting of the generator assembly to the frame of the generator set, and the
remounting of the assemblies that were removed to gain access to the generator assembly. To install the
generator assembly, refer to Connection Diagram, and proceed as follows:
a) Remounting the Generator Assembly.
(1) Support engine at flywheel housing with wooden blocks, or second hoist if available.
(2) Using the hoist, support the generator assembly and lower it carefully and slowly into position for
attachment to the engine.
(3) While still supporting the generator assembly with the hoist, attach the generator housing to the
engine, using the six M10 - 1.5 x 35 metric bolts. Torque bolts to 30 ft-lb (41 N-m).
(4) Attach the generator to the flywheel coupling, using the eight M12-1.75 bolts. Torque bolts to 85
ft-lb (115 N-m).
(5) Mount the generator housing to the frame of the generator set, using the four 5/8 - 11 x 4-1/2
bolts.
(6) Install the generator wrapper on the generator assembly, using 1/4 - 20 x 1/2 tap-tite screws.
b) Remounting the previously removed assemblies.
(1) Remount the remaining pieces of the unit in reverse order of disassembly procedure.
