Using The Search Box
Part numbers are extremely important. If you do not know the part number, purchase a factory Parts Catalog, either an original (Code 10-), used original (Code 74-), or a photocopy (Code 56-). If you cannot find the publication that you require in our book listings, please inquire. We will probably have an original that we can copy for you. We have a large library, and are constantly adding new photocopy parts catalogs and manuals to our listings.
So, after you have your parts catalog on your model to supply the pertinent numbers, you can begin to use our online store's search box in the manner intended. Look below to see examples of how Norton, Triumph, and BSA part numbers are converted to work in our search box. Note: the information below can also be found in Catalog #23, pages 186-188.
Norton
Suppose you need a cylinder head for an early 750cc Norton Commando, and you don't find it listed in any of your sources. You don't know if we have the part in stock, or what our order number may be. From your Norton parts catalog you have found this number to be 06.0988. Remove all dashes and periods and enter the number 060988 in the search box and click GO. Look below to the example.

Triumph
Triumph part numbers were converted from alpha-numeric to all numeric in 1973. In cases where letters are used in Triumph's O.E.M. part number, use the Conversion Table below to convert the letter to a number to match our part numbers. Some examples have been taken from Triumph Parts Catalogs. They are shown below the Triumph Conversion Table. Note: If you don't see a way to convert your Triumph part number, enter it in the search box as it is
In cases where letters are used in Triumph's O.E.M. part number, use the Conversion Table (above) to convert the letter to a number to match our part numbers. After the letter is converted to a two digit prefix, there are four digits that follow for the remainder of the part number. *If you only have 1, 2, or 3 digits to follow, add 3 zeros, 2 zeros, or 1 zero in between to get a total of 6 digits. In cases where the original alpha-numeric number had less than 4 digits they are filled with 0's after the prefix and before the existing digits to make a total 6 digit part number. Look below to see some examples.
BSA
BSA part numbers will have two digits before the dash, four digits after the dash, then the dash must be removed. Zeros must be used until a six digit part number is achieved. Look below to see some examples.
