Axle and Suspension Identification To assist with the identification of an Intraax axle or suspension system, reference should be made to the axle identification plate (refer to Figure ) and suspension assembly number plate (refer to Figure 2). Figure Figure 2 Axle ID Plate The axle ID plate (refer to Figure ) is usually located on the inboard side of the left-hand trailing arm and provides the following: MODEL DESCRIPTION CUSTOMER PART NUMBER AXLE SERIAL NUMBER AXLE CAPACITY The axle serial number (e.g. SK60220089) provides the following detail: Manufacturing Plant Identifier The first two digits of the axle serial number identify the manufacturing plant that manufactured the Halftraax Assembly as follows: SK Somerset Kentucky LI Lebanon Indiana CO Canton Ohio Date of Manufacture The third to eighth digits of the axle serial number identify the date the Halftraax Assembly was manufactured in US date format (Year Month - Date) e.g. 6022 Manufactured on 22 January 206 Manufacturing Sequence Number The final four digits (e.g. 0089) of the axle serial number provide the manufacturing sequence number. 3 974-2 Rev C
Suspension Assembly Number Plate The suspension assembly number plate (refer to Figure 2) is usually located on the inboard side of the righthand trailing arm and provides the following: RIDE HEIGHT; ASSEMBLY PART NUMBER; and DATE OF ASSEMBLY. Assembly Part Number The first six digits of the assembly part number identify the suspension system base model. The remaining digits identify specific options such as wheel end and brake system configuration. Base Model Identification Manufacturer (Digit ) Tri-Functional Bush Width (Digit 2) Load Capacity (Digit 3 & 4) Model (Digit 5) Specific Option Code (Digit 6) H= Hendrickson N = Narrow (3 Inch) 23 = 23,000 lbs T = Top Mount See below.

Height Control Valve HCV System Identification For AANT Intraax suspension systems, the Height Control Valve (HCV) components are common regardless of configuration, with the following exceptions: The lower linkage mounting bracket is available in two variations as follows: o Fixed to the brake chamber bracket (Refer to View A in Figure 9); o Fixed to the axle tube (Refer to View B in Figure 9). The HCV (upper) mounting bracket varies between the brake chamber and axle tube mounted lower linkage bracket. For HCV with brake chamber lower linkage mounting (Refer to View A), the HCV has an additional spacer bracket between the hanger mounting point and the HCV mounting studs. The spacer bracket is not require for HCV with the axle tube mounted lower linkage bracket. View A View B Figure 9 5 974-2 Rev C
