L977 Rev I 2 IDENTIFICATION GUIDE — TRAILER SUSPENSION AND AXLE SYSTEMS
WHERE TO FIND ID TAG ON HENDRICKSON NON-INTEGRATED TRAILER AXLES The model number, customer part number (if applicable), a description and a serial number are imprinted on an ID tag that is attached to the axle (as shown below) .
Before November 2010, trailer axle product ID tags were made of mylar and located near the center of the axle beam . After November 2010, trailer axle products have a stainless steel ID tag located on the inside edge of the brake chamber bracket .
The part number is used to identify the axle specifications . This number should be referred to when contacting Hendrickson to determine the appropriate service parts . The serial number is used to identify a particular axle along with all of the component parts as specified by the customer at the time of order . The axle description serves as a generic description of the axle assembly and can be used to determine some axle configuration parameters .
