General information
Service parts
indentication
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 51 60cc variable
displacement motors.
The parts listed include all parts which may be used when performing either “Minor Repairs”,
“Major Repairs” or “Conversions” on the Series 51 60cc motors.
NameplateEach unit will have a nameplate axed to the
housing. The nameplate will include the following
information.
Model Code
The Danfoss model code completely denes the
specic unit and must be used when ordering parts
to service this product.
Model Number
The 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 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.
Model Code
Serial No.

The letter code indicates the location of original
manufacture (assembly). “N” indicates the unit was
originally assembled in Neumuenster, Germany.
The rst number (2 digits) indicates the year of
manufacture. (“01” would indicate the unit was
manufactured in 2001)
The second number (2 digits) indicates the calendar
week of manufacture.
The third number (5 digits) is a sequential number
used to identify a specic unit.

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 L035.

C L035 00-25 515752 Bearing housing (SB-2000-049) 1
L035 92-07 00-24 743831 Bearing housing 1
All units using this order code with a date code of 92-07 and up to and including 00-24, must use part
number “743831”. All units with a date code of 00-25 and newer must use part number “515752.”.
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.
The modular design of Series 51 motors result 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 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: 664524 (9005110-9000), customers would order 9005110-9000 if ordering the part in the
United States.)
Example of a part identication
The nameplate on a Series 51 motor has an Order Code of 51V060 R S1 N HZ B1 A N C2 NNN 026 AA
E4 03 00. Use the following procedures to determine the part number of the drive shaft used on this
motor.
1) Referring to the shaft module in the Order Code (see page 7), the shaft option for this motor is
identied by the code “S1”. (51V060 R S1 N HZ B1 A N C2 NNN 026 AA E4 03 00)
2) Referring to the Service Parts List, nd the shaft group. Next nd the order code that relates to this
unit, which is “S1”. The shaft is found to be item QL10 and part number 11100478 if a speed ring is not
required. The shaft is found to be item QL11 and part number 11100479 if a speed ring is required.
