Parts Manual K and L Frame Variable Cartridge Motors
General information
The following information and procedure is used to identify the module group, item number,
Service parts
indentification
manufacture date, part number, and part name of the parts included in the K and L frame
cartridge motors.
The parts listed include all parts which may be used when performing either “Minor Repairs”,
“Major Repairs” or “Conversions” on the K and L frame cartridge motors.
Nameplate
Each unit will have a nameplate affixed to the
housing. The nameplate will include the following
information.
Model Code
The Danfoss model code completely defines the
specific 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.
The letter code indicates the location of original
manufacture (assembly). “A” indicates the unit was
originally assembled in Ames, Iowa, U.S.A.
The first number (2 digits) indicates the year of
manufacture. (“01” would indicate the unit was
manufactured in 2001)
Model No./Ident No.

The second number (2 digits) indicates the calendar
week of manufacture.
The third number (5 digits) is a sequential number
used to identify a specific unit.

General information
Date code
Service bulletins
Procedure to identify a part
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 from the nameplate to determine which service part number you need to order.
EXAMPLE: The service part desired is Item B003.
Order Date Date
Code Item Begin End Part Number Part Name Usage
C B003 00-02 9004104-0100 O-ring (SB-1999-056) 1
B003 99-16 00-01 9004104-1080 O-ring 1
All units using this order code with a date code of 99-16 and up to and including 00-01, must use
part number “9004104-1080”. All units with a date code of 00-02 and newer must use part number
“9004104-0100.”.
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 K and L frame units result in a simplified service parts list and part number
identification procedure.
The same item numbers are used for same part names on all units within a product type. (Example:
The lip seal - Item M003, 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 first 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 identification
The nameplate on a L frame motor has an Order Code of LC 25CN E RNF F11 S N N AF F18 NNN NNN.
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
identified by the code “E”. (LC 25CN E RNF F11 S N N AF F18 NNN NNN)
2) Referring to the Service Parts List, find the shaft group. Next find the order code that relates to this
unit, which is “E”. The shaft is found to be item D001 and part number 4400009.
