Install the washer and alternator rotor bolt [A].
Confirm the alternator rotor fit or not to the crankshaft
before tightening it with specified torque.
Install the rotor bolt and tighten it with 70 N·m (7.0 kgf·m,
52 ft·lb) of torque.
Special Tools - Grip [B]: 57001-1591
Stopper [C]: 57001-1679
Rotor Holder [D]: 57001-1690
Remove the rotor bolt and washer.
Check the tightening torque with flywheel puller.
Special Tool - Flywheel Puller Assembly, M38 × 1.5/M35 ×
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 washer, and dry
them with a clean cloth. Then, confirm that it is not pulled
out with above torque.
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
shaft [A], and install it and starter idle gear [B].

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
