Service partsindentification

Use this information and procedure to identify the module group, item number, manufacture date, part number, and part name of parts included in the LPV closed circuit pump. Use the parts listed when performing minor repairs, major repairs, or conversions on LPV closed circuit pumps.

Nameplate

General information

Each unit has a nameplate affixed to its housing. The nameplate includes this information:

Model Code The Danfoss model code defines the specific unit. Use it when ordering parts to service this product.

Model Number The manufacturing factory uses Danfoss’ model numbers. On repeat orders, order a complete unit by the model number.

Serial Number The Danfoss serial number identifies the manufacture date and unit sequence in the build. The serial number also identifies the unit’s 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 first number (2 digits) indicates the year of manufacture. (06 would indicate the unit was manufactured in 2006).

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 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 C090

All units using this order code with a date code of 94-34 and up to and including 98-01, must use part number “4570025”. All units with a date code of 98-02 and newer must use part number “4570245.”.

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 LPV units 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. (Example: The lip seal - Item D01 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: 688622 (9004700-1907), customers would order 9004700-1907 if ordering the part in the United States.)

Example of a Part Identification The nameplate on an LPV pump has an Order Code of LPV 035 E3 B A C C A G A A BFF DS F FF A NNN. Use the following procedures to determine the part number of the input shaft used on this pump.

1. Referring to the input shaft module in the Order Code (see page 7), the input shaft option for this pump is identified by the code “C”. (LPV 035 E3 B A C C A G A A BFF DS F FF A NNN).

2. Referring to the Service Parts List, find the shaft group. Next find the order code that relates to this unit, which is “C”. The shaft is found to be item E01 and part number 4250202.
