15. Install the generator lifting tool (Carrier Transicold
part number 07-60085-00) into top two generator
mounting holes. Rig hoist and remove generator
assembly and spacer. If not immediately rein-
stalling a generator, remove the guide rods.

a. Ensure the two dowel pins are installed in the
bell housing with the chamfer facing out (see
Figure 8-23).

b. Remove the flywheel and inspect it for any debris or
damage.
c. Install spacer (see Figure 8-22) onto the bell hous-
ing over the dowel pins.
d. Locate two screw holes on the face of the crank-
shaft which are located approximately 12.7 mm
(0.5 in) apart. All other screw holes are approxi-
mately 19mm (0.75 in) apart (See Figure 8-23).
e. Assemble two guide rods (Carrier Transicold part
number 07-60122-00) into the two holes in the
crankshaft located in the previous step. Assemble
the third rod across from the first two rods.
f. Install the flywheel on the crankshaft using the guide
rods to align properly. Ensure the flywheel mates
with the crankshaft with no rocking or side to side
movement.
g. Ensure the generator is facing so that the leads exit
the stator winding are on the side away from the en-
gine. Install the lifting tool in the top two holes so
that the dowel pin holes will align when the assem-
bly is installed against the spacer. Lift the generator
using the lifting tool and bring it in place at the back
of the engine.
h. The mounting holes on the rotor have two holes
offset to match the ones in the crankshaft and fly-
wheel. Locate them and turn the engine to line up
the guide rods in the crankshaft with the offset holes
in the rotor.
NOTE
The generator rotor will not turn in the stator.
i. Slide the rotor over the guide rods and mate the
stator with the spacer. Ensure the dowel pins in the
bell housing are fully engaged in the stator.
NOTE
The generator should slide freely on the guide
rods if the holes in the generator rotor are
matched correctly with the crank shaft holes.
Otherwise it will bind up and the stator will not
mate properly with the spacer.
