• Remove stud from tapered engine shaft.

Assembly

NOTE:
Inspect for any loose debris, obstructions
or flaws on the engine adaptor, stator laminations,
rear bearing carrier, the threaded hole in the tapered
shaft and the surface of the mating surface of the
rotor before proceeding with the rotor installation.
Rotor Installation
Installation of the rotor is accomplished by placing the rotor
on the end of the tapered drive shaft.There is no concern
for timing the rotor to the engine.
• Slip the washer on the rotor bolt.
• Insert the rotor bolt and washer through the bearing
end of the rotor (Figure 4.25).
• Start the bolt into the threads of the tapered shaft by
hand, being careful not to "crossthread" the bolt.
• Torque to specifications.

NOTE:
Torque specifications can be found in the
appendix of this guide.
Stator Installation
There are a number of alignment marks that should be
noted when installing the stator assembly.The first of these
is located on the engine adapter housing.
Looking straight at the unit as it is assembled thus far, you
should notice a small notch just above and inboard of the
stator bolt boss, at the 2 o'clock position (See Figures 4.25
and 4.26).
