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
The parts listed include all parts which may be used when performing either “Minor Repairs”, “Major
Repairs” or “Conversions” on the.
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).
The first number (2 digits) indicates the year of manufacture. 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.
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 G30
Order CodeItemDate BeginDate EndPart NumberPart NameQty. per
80G3089-178000243End cap gasket 1
G3089-168000151End cap gasket
All units using this order code with a date code prior to 89-17 must use part number “8000151.” All units
with a date code of 89-17 and newer must use part number “8000243.”
About service bulletins
AService 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 receive them.
The modular design of this product results 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..
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: 314583 (9008000-0118), customers would order 9008000-0118 if ordering the part in the
United States).
Example of a part identification (MPV044D)
The nameplate on a Series 40 pump has an Order Code of MPV-044-D-B-A-G-W-A-G-NN-A-A-BJJ-DR-AFF-A-NNN. Follow the steps below to determine the part number of the drive shaft used on this pump:
1. Referring to the input shaft module in the Order code, variable displacement pump, the output shaft
option for this motor is identified by the code G. (MPV-044-D-B-A-G-W-A-G-NN-A-A-BJJ-DR-A-FF-ANNN)
2. Referring to the Service Parts List, find the shaft group
3. Find the order code that relates to this unit, which isG.
4. Follow along shaft item E01 to find the part number
