Forward
This book contains service information for the engine(s)
listed on the title page.
The life of your engine unit and the delivery of the high
performance built into it will depend on the care it
receives throughout its life. It is the operator’s
responsibility to ensure that the engine is correctly
operated. We consider it to be in your interests to enlist
the aid of an authorized EDI Distributor, not only when
repairs are required but also for regular maintenance.
Distributors are listed at the back of this manual.
Engines manufactured by Ford Motor Company are
available through EDI Distributors. When in need of
parts or service, contact your local Authorized
Distributor. In overseas territories, in the event of
difficulties, communicate directly with the supervising
EDI affiliated Company in your area whose address
appears at the end of this book.
Where the terms “Right” or “Left” occur in this
publication, they refer to the respective sides of the
engine when viewed from the rear or flywheel end.
Pistons and valves are numbered from the front or
timing cover end of the engine commencing at No. 1.
You may find that your engine assembly includes
optional equipment not specifically covered in the
following text. Nevertheless, the service procedures
outlined in this book still apply to your engine.
Engine Identification
Because Ford Power Products markets such a wide
range of industrial gasoline and diesel engines -
manufactured both in the U.S. and overseas - it is
important that you have as complete identification of the
engine as possible in order to provide the correct
replacement parts. Review the list in the back of this
book, for an EDI distributor in your area. You can obtain
a standard parts listing describing the parts. It remains
a distributor function to identify the part number.
An identification Decal is affixed to the valve cover of
the engine. The decal contains the engine serial
number which identifies this unit from all others. Use all
numbers when seeking information or ordering
replacement parts for this engine.
Parts and Service
Replacement parts can be obtained through your local
EDI Distributor listed in the back portion of this manual.
They also may be found in the yellow pages under
“Engines” or contact EDI directly at 1 800 220 2700.
EDI Distributors are equipped to perform major and
minor repairs. They are anxious to see that all of your
maintenance and service needs are quickly and
courteously completed.
Description and Operation
Section 01 of this manual covers general procedures
and diagnosis of the engine system, including base
engine repair procedures, that would be common to
most engines. Refer to Section 02 for more specific
service information on the DSG-423 engine.
The DSG-423 engine incorporates a closed positive
crankcase ventilation system and an exhaust emission
control system.
The engine’s, fuel, ignition, emissions system and
exhaust system all affect exhaust emission levels and
must be maintained according to the maintenance
schedule. Refer to the Maintenance and Operator’s
Handbook or contact your nearest EDI distributor listed
