Install hexagon head capscrews (16) and lockwashers (17). Verify that hexagon head capscrews (16) have
sufficient clearance to be freely turned by hand. If the hexagon head capscrews freely turn, it indicates
that the engine is resting on the engine mount and not being suspended on the hexagon head capscrews
(16). If the engine is resting on mounts, proceed directly to step (18), below. Otherwise, correct the
problem by shimming in accordance with the following steps:
(a)
Remove all hardware (14 through 17) retaining engine to rear engine supports (6).
(b)
Raise the engine slightly to allow installation of shims (18) in 0.015 increments between engine and
rear engine support.
(c)
Install hexagon head capscrews (14) and lockwashers (15). Tighten, but do not torque.
(d)
Install hexagon head capscrews (16) and lockwashers (17). Verify that hexagon head capscrews
(16) have sufficient clearance to be freely turned by hand. If not, repeat steps (a) through (c), above,
until engine is properly shimmed to rear engine supports (6).
(18)
If hexagon head capscrews (16) are free, torque hardware (14 and 16) to 200 pound-feet (272 newton-
meters).
(19)
Remove all hexagonal nuts (9) and Iockwashers (8) securing rear engine supports (6) to skid base.
(20)
Raise the rear of the engine and insert 1/2 inch (12 mm) spacer blocks between the skid base and the rear
engine supports (6). Lower the engine until the supports rest on the spacer blocks.
(21)
Install two lineup studs in the flywheel for generator drive plate (flexible discs) alignment at the 3 and 9
o'clock positions.
WARNING
Use of slings, chains, or lifting hoists not rated for the weight of the engine assembly may
result In Injury to personnel and falling damage to equipment.
(22)
Rig the generator for lifting with a hoist or overhead crane rated for a minimum of 6,000 pounds (2722 kg)
and a minimum height clearance of 150 inches (3816 mm) (See Figure 2-9). There are two lifting brackets
welded to the top of the generator. Use locking lifting hooks on the brackets and raise the hoist to remove
slack from the slings and lifting chains, but do not lift generator at this time.
WARNING
To minimize potential failing damage, clear the area of personnel and other equipment when
attempting to lift heavy equipment.
CAUTION
Take care when lifting generator, as there is enough slack In generator cables and wiring to
remove generator without disconnecting cables and wiring, providing the generator is not
lifted and moved beyond limits stated In paragraph 2-15b(9).
NOTE
This task requires two people.
(23)
Lift generator approximately 0.500 inches (12.7 mm) or until generator feet clear generator mounting pads.
Slowly move generator towards engine and guide the drive plate (flexible discs)to the lineup studs installed
in the flywheel in step (7), above. This will require manual alignment while generator is suspended on
lifting device. Generator adapter ring must be properly seated in flywheel housing before proceeding to
next step.
(24)
See Figure 2-4, detail A Install all the hexagon head capscrews and lockwashers securing the generator
adapter to the engine flywheel housing. Torque the capscrews on the lower half of the adapter to 50
pound-feet (68 newton-meters). Leave the upper half of the bolt circle finger tight
