General information
Service parts
indentification
The following information and procedure is used to identify the module group, item
number, manufacture date, part number, and part name of the parts included in the Series
90, 250 cc variable displacement pumps.
The parts listed include all parts which may be used when performing either “Minor
Repairs”, “Major Repairs” or “Conversions” on the Series 90, 250 cc pump.
Nameplate Each unit will have a nameplate axed to
the housing. The nameplate will include the
following information.
Model Number
The Sauer-Danfoss model number is used by
the factory in manufacturing. On repeat orders,
a complete unit can be ordered by the model
number.
Model Code
The Sauer-Danfoss model code completely
denes the specic unit and must be used
when ordering parts to service this product.
Serial Number
The Sauer-Danfoss serial number is used to
identify the manufacture date and the unit
sequence in the build. The serial number is also
used to identify the units warranty time period.
Model No./Ident No.

The letter code indicates the location of original
manufacture (assembly). “A” indicates the unit
was originally assembled in Ames, Iowa, USA.
“N” indicates the unit was originally assembled
in Neumunster, Germany.
The rst number (2 digits) indicates the year of
manufacture. (“01” would indicate the unit was

General information
Date code
The date code is dened as the year and week of manufacture. The same item number
may list more than one part number. This indicates that there is more than one
conguration for that item number. You will see that there are dierent date codes for the
dierent part numbers. Find the date code of your unit from the nameplate to determine
which service part number you need to order.
EXAMPLE: The service part desired is Item E10
Order Date Date Qty. per
Code Item Begin End Part Number Part Name Model/Kit
80 E10 92-19 746107 Side cover 1
G30 89-41 92-18 340133 Side cover (SB-1992-003) 1
All units using this order code with a date code of 89-41 and up to and including 92-18,
must use part number “340133”. All units with a date code of 92-19 and newer must use
part number “746107.”
Service bulletins A Service Bulletin Number (SB-_ _ _ _ - _ _ _) may follow the “Part Name” of the part you
desire. You must read that Service Bulletin prior to ordering that part. The information
contained in these Service Bulletins, as of the print date of this bulletin, are included
at the end of this manual. Service Bulletins contain more detailed information such as
interchangeability, what additional parts are involved, etc. It is suggested that you add
additional Service Bulletins to this manual as you recieve them.
Procedure to identify a
part
General
The modular design of Series 90 units results in a simplied service parts list and part
number identication procedure.
The same item numbers are used for same part names on all units within a product type.
(Example: The lip seal - Item L40 has the same item number on all pumps.)
A part number that has another number following it in parentheses is done to make this
a world wide manual. The rst number is sold in Germany. The number in parentheses
is sold in the United States. (Example: 001149 (9004201-6200), customers would order
9004201-6200 if ordering the part in the United States.)
Example of a Part Identification
The nameplate on a Series 90 pump has an Order Code of 90L250 KA 1 BC 80 T 4 C8 K 03
NNN 42 42 24. Use the following procedures to determine the part number of the drive
shaft used on this pump.
1) Referring to the input shaft module in the Order Code (see page 7), the input shaft
option for this pump is identied by the code “C8. (90L250 KA 1 BC 80 T 4 C8 K 03 NNN 42
42 24)
2) Referring to the Service Parts List, nd the shaft group. Next nd the order code that
relates to this unit, which is “C8”. The shaft is found to be item L100 and part number
504338.
