When classifying dealer parts stock, start with the routine service intervals. The wear demand under local road conditions and the collision repair and low-frequency large items must be confirmed in writing before the next step begins. Stock service parts by service interval, wear parts by local road conditions, and collision parts by repair capability. Note the routine service intervals in the order file and attach the basis for the wear demand under local road conditions; pause the next step if the collision repair or low-frequency large items change.
