Parts Manual

Series T90 Axial Piston Pump Size 75cc

General Information

Service parts indentification

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 T90 75 cc variable displacement pumps.

The parts listed include all parts which may be used when performing either “Minor Repairs”, “Major Repairs” or “Conversions” on the Series T90 75 cc pump.

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). “C” indicates the unit was originally assembled in Shanghai, China.

The first 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 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 G30

General Information

Procedure to identify a part

General

The modular design of Series T90 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 L40 has the same item number on all pumps.)

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

The nameplate on a Series T90 pump has an Order Code of T90L075 MA 1 NN 60 S 3 S1 D 03 MKX 35 35 24. Use the following procedures to determine the part number of the drive 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 “S1. (T90L075 MA 1 NN 60 S 3 S1 D 03 MKX 35 35 24)

2)Referring to the Service Parts List, find the shaft group. Next find the order code that relates to this unit, which is “S1”. The shaft is found to be item L100 and part number 8100264.
