Service parts

indentication

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 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 axed to the

housing. The nameplate will include the following

information.

Model Code

The Sauer-Danfoss model code completely denes

the specic 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.

The third number (5 digits) is a sequential number

used to identify a specic unit.

Parts Manual Series 40 M46 Axial Piston Motors

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 40 units results in a simplied service parts list and part number

identication 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 Identication

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 identied 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.

Date code

The date code is dened 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 conguration for that item number.

You will see that there are dierent date codes for the dierent 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

3113 86-23 4460407 Thrust plate 1

3113 84-31 86-22 4460033 Thrust plate 1

Order Date Date

Code Item Begin End Part Number Part Name Usage

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”.
