Each tandem pump will have a nameplate affixed to the housing.
The name plate will include the following information.
Model Code
The Sauer-Sundstrand 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-Sundstrand 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-Sundstrand 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
Tandem pumps manufactured in Germany will have an identifi-
cation 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 Neumünster, 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 item number may list more than one
part number. This indicates that there is more than one configuration for that item number. You will see that there
are different date codes for the different part numbers. Find the date code of your unit via the nameplate to
determine which service part number you need to order.
EXAMPLE: The service part desired is ItemC01.

All units using this order code with a date code of 91-07 and up to and including 96-20 must use part number
“4510126”. All units with a date code of 96-21 and up must use part number “4250102”.
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 M25 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
cylinder block kit - Item Number B22 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 Service
Parts Manual. The first number is sold in Germany. The number in parentheses is sold in the United States.
(Example: 5000093 (9008000-0132), Customers would order 9008000-0132 if ordering the part in the United
States.)
Example of a Part Identification
The nameplate on an M25 tandem pump has an Order Code of MPT025C S R A E NN B A A A BDD DL A FF B C
A A BDD DR A FF A CXN. Use the following procedures to determine the part number of the shaft used on this
tandem pump.
1) Referring to the input shaft module, in the Order Code (see page 5), the input shaft option for this unit is
identified by the code “S” (MPT025C S R A E NN B A A A BDD DL A FF B C A A BDD DR A FF A CXN)
2) Referring to the Service Parts List, find the shaft group. Next find the order code that relates to this unit, which
is “S”. The shaft is found to be item E01S and part number 4250001.
