(1)
Tighten the pulley nut to the following
torque:...............................................................45 to 55 Nm
(33 to 40 lb-ft)
(2)
Tighten the terminal nut "W" to the following
torque:................................................................2 to 2.5 Nm
(17 to 22 lb-in)
The "W" terminal is the source of the alternating current from
the stator.
NOTE:
The peak voltage at the “W” terminal must not be
less than the output voltage at the “B+” terminal.
The peak voltage at the “W” must not be more
than two volts greater than the “B+” terminal.
(3)
Tighten terminal nut "D+" to the following
torque: .......................................................1.45 to 1.95 Nm
(13 to 17 lb-in)
The "D+" terminal is the field excitation terminal. The battery
must be connected in order to energize the circuit.
(4)
Terminal nut "B+"
Tighten terminal nut "B+" on the 12 volt
alternator to the following
torque: .....................................3.5 0.9 Nm (31 8 lb-in)
Tighten terminal nut "B+" on the 24 volt
alternator to the following
torque: .................................7.75 0.25 Nm (69 2 lb-in)
(5)
Tighten terminal nut "B-" on the 24 volt
alternator to the following
torque: .....................................3.6 0.8 Nm (32 7 lb-in)
