HOW TO USE THIS MANUAL

Engine Shop Rebuild and Parts Manual

This manual is designed to suit the needs of mechanics at all levels of experience with the E-Z-GO 4-cycle engine. The

outline format will allow the mechanic to choose the level of instructional detail needed to completely disassemble, diag-

nose, repair/overhaul and reassemble the engine.

The manual is divided into four major operational sections, which are each divided into smaller operational sections. At

the beginning of each major section is a list of tools that will be required to perform the operations desired in that sec-

tion. Do not use non-specified tools (vise grips®, hammers, adjustable wrenches etc.). The use of these tools

could cause permanent damage to the engine components.

WE STRONGLY RECOMMEND that no matter what your experience level, you use this manual as a guide when disas-

sembling, repairing/overhauling and reassembling the engine. Before working on the engine, read and understand the

text and in particular each NOTE, CAUTION and WARNING.

Some illustrations may show components that differ from your engine. This is the result of ongoing improvements to the

engine design.
