Section 15 Alternator Disassembly/Reassembly
Note: Refer to Section 16 for unique differences on
35- 40 kW generator sets equipped with
4PX/4QX alternators.
15.1 Introduction
Before beginning the alternator disassembly procedure,
carefully read all safety precautions at the beginning of
this manual. Please observe these precautions and
those included in the text during the disassembly/
reassembly procedure.
For enclosed units, remove the enclosure door, roof,
and side and end panels as required to access the
generator set.
Mark leads as they are disconnected. Refer to the
respective wiring diagram during reassembly. See the
list of related materials in the Introduction Section of this
manual for literature part numbers.
Any cranes, hoists, or other lifting devices used in the
disassembly or reassembly procedure must be rated for
one-half ton or greater.
The following procedures cover many models and some
steps may not apply to a particular engine. Use
Figure 15-1 and Figure 15-2 to help understand
component descriptions and general configuration of
the alternator and associated components of the
junction box and control box.
Use disassembly procedure as a step-by-step means to
help disassemble the alternator. The disassembly
procedure provides important information to minimize
disassembly time and indicates where special
configurations exist that may require taking notes. The
reassembly procedure includes important alignment
steps and provides critical torque specs.
