4. Set the nozzle holder to the nozzle tester and check
first nozzle opening pressure, spray condition, seat oil
tightness and each part for oil leaks.
5. When replacing the nozzle, replace the nozzle, lift
piece, pins and spacer as a set with the nozzle service
kit.
CAUTION:
Pre-lift will not be as specified if only the nozzle is
replaced.

GENERAL DESCRIPTION
GENERATOR STARTER MOTOR
066L300004065L300002
The basic charging system is the IC integral regulator charging system. The internal components are connected
electrically as shown in charging circuit diagram.
The generator features a solid state regulator that is mounted inside the generator. All regulator components are
enclosed into a solid mold, and this unit along with the brush holder assembly is attached to the slip ring end frame.
The generator voltage setting cannot be adjusted.
The starter motor circuit is composed of a 4-pole 4-brush type direct current series motor. The starter motor circuit
utilizes negative ground polarity.
