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
Order Code Item Date Begin Date End Part Number Part Name Usage
N H10 89-38 8800668 Loop flushing
H10 87-02 89-37 8800021 Loop flushing
All units using this order code with a date code of 87-02 and up to and including 89-37, must use part
number “8800021”. All units with a date code of 89-38 and newer must use part number “8800668”.

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 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: 515965 (9005110-5600), customers would order 9005110-5600 if ordering the part in the
United States.)
Example of a Part Identification
The nameplate on a Series T90 motor has an Order Code of T90M100 NC 0 N 8 N 0 S1 W 00 NNN 00 00 F0.
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, the shaft option for this motor is identified by the
code “F1”. (T90M100 NC 0 N 8 N 0 S1 W 00 NNN 00 00 F0)
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 11012429.
