Each pump will have a nameplate affixed to the housing. The
name plate will include the following information.
Model Code
The Sauer-Danfoss model code completely defines the
specific unit and must be used when ordering the complete unit
for the first time or for ordering parts to service the product.
Model Number
The Sauer-Danfoss model number is used by the factory in
manufacturing. On repeat orders, a complete unit can also be
ordered by the model mumber.
Serial Number
The Sauer-Danfoss serial number is used to identify the
manufacturing location, manufacturing date and the unit se-
quence in the build. The serial number is also used to identify
the unit's warranty time period.
Identification Number
Pumps manufactured in Germany will have an identification
number instead of a model number.
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 NeumŸnster, Germany.
The first number (2 digits) indicates the year of manufacture.
("92" would indicate the unit was manufactured in 1992)
The second number (2 digits) indicates the calender week of
manufacture.
The third number (5 digits) is a sequential number used to
identify a specific unit.

Date Code
The date code is defined as the year and week of manufacture. The same reference number may list more than
one part number. This indicates that there is more than one configuration for that reference number. You will see
that there are different date codes for the different part numbers. Find the date code of your unit via the name-
plate to determine which service part number you need to order.
EXAMPLE: The service part desired is Item E10.
Order Date Code Qty. per
Code Item Begin → End Part Number Description Model
E10 92-19 →746107 Side cover (SB-9203) 1
" 89-41 → 92-18 340133 Side cover 1
All units using this module group 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 up must use part number 746107.
Service Bulletins
A Service Bulletin Number (SB- _ _ _ _) may follow the Description of the part you desire. You must read that
Service Bulletin prior to ordering that part. A copy of each of 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 receive them.
Procedure to Identify a Given Part/Part Number
General
The modular design of Series 90 units results in a simplified Service Parts List and Part Identification Procedure.
The same item numbers are used for same part description on all units within a product type. (Example: The shaft
seal - Item Number L40 has the same item number on all variable displacement pumps.)
All Item Numbers begin with a letter. The letter identifies a particular module. (Example: any items beginning with
K relate to the charge relief valve; items beginning with L relate to the input shaft components, etc.)
Example of a Part Identification
The nameplate on a Series 90 pump has an Order Code of 90L180 MA 1 C 8 S 3 F1 H 03 NNN 35 35 24. Use
the following procedures to determine the part number of the filtration kit used on this pump.
1) Referring to the input shaft module in the Model Code (see page 5), the shaft option for this unit is identified by
the code F1 (90L180 MA 1 C 8 S 3 F1 H 03 NNN 35 35 24)
2) Referring to the Service Parts List, find the shaft group. Next find the order code that relates to this unit, which
is F1. The shaft is found to be item L1 and part number 772590.
