Parts Manual Series 40 M46 Axial Piston Motors
General information
The following information and procedure is used to identify the module group, item number,
Service parts
indentication
manufacture date, part number, and part name of the parts included in the series 40 M46 xed
displacement motor and variable displacement motor.
The parts listed include all parts which may be used when performing either “Minor Repairs”,
“Major Repairs” or “Conversions” on the M46 motors.
Nameplate
Each unit will have a nameplate axed to the
housing. The nameplate will include the following
information.
Model Code
The Sauer-Danfoss model code completely denes
the specic unit and must be used when ordering
parts to service this product.
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.
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.
The letter code indicates the location of original
manufacture (assembly). “A” indicates the unit was
originally assembled in Ames, Iowa, USA.
The rst number (2 digits) indicates the year of
manufacture. (“97” would indicate the unit was
manufactured in 1997)
The second number (2 digits) indicates the calendar
week of manufacture.

Parts Manual Series 40 M46 Axial Piston Motors
General information
The date code is dened as the year and week of manufacture. The same item number may list more
Date code
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 H10
Order Date Date
Code Item Begin End Part Number Part Name Usage
3113 86-23 4460407 Thrust plate 1
3113 84-31 86-22 4460033 Thrust plate 1
All units using this order code with a date code of 84-31 and up to and including 86-22, must use part
number “4460013”. All units with a date code of 86-23 and newer must use part number “4460407”.
Service bulletins
Procedure to identify a part
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.
General
The modular design of series 40 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 3201 has the same item number on all motors.)
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: 5000731, customers would order 373282 (9001315-0011) if ordering the part in the United
States.)
Example of a Part Identication
The nameplate on an M46 xed displacement motor has an Order Code of MMF046C A E A B B NNN.
Use the following procedures to determine the part number of the drive shaft used on this motor.
1) Referring to the output shaft module in the Order Code (see page 7), the output shaft option for this
motor is identied by the code “E”. (MMF046C A E A B B NNN)
2) Referring to the Service Parts List, nd the shaft group. Next nd the order code that relates to this
unit, which is “E”. The shaft is found to be item 3301 and part number 4460582.
