You must discard all damaged components\b TH\bS CHART \bS NOT ALL\bNCLUS\bVE. Rim par ts marked with EXA\bTLY the same size and type identification stamps may be used together even though they are not shown on this char t\b Rim par ts marked with different size and type identification stamps should NEVER be used together\b Just because components come in together, does not mean they are matched\b See WARNINGS\b HOW TO MATCH RIM PARTS \b. Find the stamped identification on the rim base and ring(s). Refer to the pictures (see pictures bottom right) to help find the locations of the stamps. Identify the parts based on the stamps themselves— DO NOTidentify the parts based only on the way they look. 2. If you cannot find the identification stamp— STOP!NEVE\b use a rim part that you cannot identify from the stamp. 3. Match the markings found on the rim base with those shown in the “Rim Base Identification Stamping” column in the tables below. 4. Continue reading the same line across the table to find the proper markings for the matching side ring (or lock ring and flange). \f. NEVE\b assemble mismatched rim parts (see WARNINGS above). If the identification stamps on the parts do not match—STOP! Select serviceable replacement parts from stock or obtain them from a rim supplier. 6. If you are working on a rim/wheel assembly of discontinued parts that are cracked, bent, worn, pitted by corro sion, or unserviceable in any way, for whatever reason—STOP! You must replace the entire discontinued assem bly with one that is in current production. Examples of unserviceable parts are shown in the photos above. HOW TO READ THESE TABLES Example A – TwoPie\fe Rim/\bide Ring Assembly \b. The rim base and side ring to be assembled have identification stamps like the ones shown to the right. 2. Find 20 x 7.\f rim size in the “Rim Size” column in the tables below. Locate 20 x 7.\f FL in the “Rim Base Identification Stamping” column. 3. Continue reading the same line across the table. Find the matching side ring markings in the “Side Ring Identification Stamping” column. 4. One of the proper markings is: 20 x 7.\f FL. This matches the stamp of the side ring shown in the photo. These parts are matched and will make a proper assembly. Example B – ThreePie\fe Rim/\bide Ring Assembly \b. Follow Steps \b and 2 in Example A – TwoPiece Assembly. 2. Read across the table in the same row to find the proper match in the “Lock Ring Identification Stamping” and “Flange Identification Stamping” columns.
