General information
The date code is dened as the year and week of manufacture. The same item number may list more
Date code
than one part number. This indicates that there is more than one conguration for that item number.
You will see that there are dierent date codes for the dierent 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 H10
Order Date Date
Code Item Begin End Part Number Part Name Usage
N H10 89-38 8800668 Loop flushing spool, defeated 1
H10 87-02 89-37 8800021 Loop flushing spool, defeated (SB-1989-020) 1
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.”.
Service bulletins
Procedure to identify a part
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 Series 90 units results in a simplied service parts list and part number
identication 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 rst 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 identication
The nameplate on a Series 90 motor has an Order Code of 90K042 NC 0 N 8 N 0 C4 N 00 NNN 00 00 00.
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
identied by the code “C4”. (90K042 NC 0 N 8 N 0 C4 N 00 NNN 00 00 00)
2) Referring to the Service Parts List, nd the shaft group. Next nd the order code that relates to this
unit, which is “C4”. The shaft is found to be item L100 and part number 755801.
