Isuzu AA-6SD1T Diesel Engine Workshop Manual – PDF DOWNLOAD 

Foreword:

• This Workshop Manual has been prepared as a guide for the service and repair of
  the Model AA-6SD1T diesel engine.
• A general table of contents is shown on the following page, and more detailed
  subsections are listed at the beginning of each respective chapter.
• This manual was first prepared in April, 2001, but subsequent changes in design
  may result in modifications to certain values and other information in this Manual.

GENERAL SERVICING PRECAUTIONS:
11. Before performing any inspections or maintenance work, disconnect the battery’s ground cable to
prevent any damage from shorted wires.
12. Always use the proper tool for the job.
When a special tool is designated for a job, be sure to use only that special tool.
13. When replacement parts are required, consult the appropriate Isuzu parts catalog and use only
“Genuine Isuzu Parts.”
14. Never reuse any cotter pins, gaskets, seals, o-ring, lock washers, or self-locking nuts removed in the
course of disassembly.
15. To facilitate reassembly, lay out engine parts in logical groups in the order in which they are removed.
Be especially careful to replace nuts and bolts in their proper locations, since characteristics such as
length and hardness may differ depending on the installation position.
16. Use identification labels or tags to mark valves, bearings, and pistons, to prevent confusing their
proper order and sequence.
