to avoid losing it; remove the rod for
reassembly.

24. With the chain hoist, unweight the engine
gently. Use a pry bar to carefully pry
between the engine and the stator frame in
order to unseat the bearing on the end of
the rotor shaft. Separate the engine and
rotor from the stator frame, supporting the
rotor by hand to prevent damage to the
rotor core.
25. Move the engine and rotor assembly to a
bench. The engine is off balance with the
rotor still attached; therefore, support the
end of the rotor with a wooden two-by-
four before unhooking the chain hoist.
