Mack — AL40

Description

This air suspension is a Hendrickson HAS designed for a Mack chassis with 40,000 lbs. capacity. It features a Z-spring main support with large air springs atop a cross channel. The Mack AL is used on CXN, CHN, CX, CH, CV, CT, CL and RD model chassis equipped with either Mack, ArvinMeritor or Eaton rear axles.

This suspension is optimally designed for on-road, line-haul applications (tankers, grocery operations, beverage trucks, car carriers, vans or flatbeds) and situations where ride quality, loaded and unloaded, is important.

Tech Tips and Additional Resources

ATRO offers replacements for the torque rods, torque rod bushings and the slipper wear pads (with or without hardware):

Torque Rods

Transverse rod
- TR62-41183 – 18 ¼" c-c with standard bushings, TS38000/TM38000; rotating pin for easy installation, chemically resistant poly (replaces OE# 25168854)
Longitudinal rods
- TR62-417M1 – 14.41" c-c length, small eye rod, TS00-22500 in each end; rotating pin, chemically resistant poly (OE# 25112948)
- TR50-41102 – 14 3/8" c-c, standard eye rod option, TS38000 (2 ¾" outer diameter), rotating pin, chemically resistant poly
- TR50-45950 – adjustable, small eye rod, TS00-22500 in each end; rotating pin, chemically resistant poly (OE# 25168255)
- Both the TR62-417M1 and TR50-45950 are replacing OE rods that have rubber jam-style bushings with 1 7/8" outer diameters. ATRO’s TS00-22500 only fit ATRO’s rods – the 2" outer diameter makes room for an outer sleeve. This outer sleeve achieves a press-fit into the rod and allows for inner pin rotation.
- To rebush OE rod with ATRO Poly, use PL1146 (no outer sleeve, no pin rotation)

Wear Pads

Wear pad kits
- WP50-29004 – WP50-29929 pad with retaining clips and tapping screws (old style)
- WP50-29005 – WP50-29929 pad with lock pins (current style)
Wear pad, no hardware
- WP50-29929 – chemical and abrasion resistant poly
