Install the washer [A].
Confirm that the alternator rotor fits onto the crankshaft
before tightening it with specified torque.
Apply molybdenum disulfide oil solution to the threads
and seating surface of the rotor bolt.
Install the rotor bolt [B] and tighten it with 68.5 N·m (6.99
kgf·m, 51 ft·lb) of torque.
Remove the rotor bolt and washer.
Check the tightening torque with flywheel puller.
If the rotor is not pulled out with 20 N·m (2.0 kgf·m, 15
ft·lb) of drawing torque, it is installed correctly.
If the rotor is pulled out with under 20 N·m (2.0 kgf·m, 15
ft·lb) of drawing torque, clean off any oil dirt or flaw of the
crankshaft and rotor tapered portion, and dry them with
a clean cloth. Then, confirm that it is not pulled out with
Reinstall the rotor bolt and washer.
Tighten the alternator rotor bolt while holding the alterna-
tor rotor steady with the rotor holder.

Apply a thin coat of molybdenum disulfide grease to the
shafts [A], and install them.
Install the torque limiter [B] and starter idle gear [C].

There are three types of alternator failures: short, open
(wire burned out), or loss in rotor magnetism. A short or
open in one of the coil wires will result in either a low output,
or no output at all. A loss in rotor magnetism, which may be
caused by dropping or hitting the alternator, by leaving it
near an electromagnetic field, or just by aging, will result in
