WG9100520034 Front Leaf Spring Shackle Hanger Assembly for SINOTRUK HOWO

WG9100520034 Front Leaf Spring Shackle Hanger Assembly for SINOTRUK HOWO

To support the weight of the vehicle's front end and engine; to allow the leaf springs to freely stretch and deform when the vehicle is traveling on bumpy roads, absorbing vibrations.

High fatigue life: Designed for heavy-duty trucks, it undergoes rigorous heat treatment processes, resulting in excellent fatigue resistance and crack propagation resistance.

High structural rigidity: The castings have uniform wall thickness and precise hole spacing (ISO9001 certified standard), making them resistant to deformation under extreme torsional loads or emergency braking.

Double wear-resistant protection: The inner lining holes are typically pre-loaded with high-wear-resistant steel or copper sleeves to reduce direct friction between the steel pins and the lifting lug body.

Sinotruk: HOWO 7 series (such as the 371hp dump truck and 380hp tractor), HOWO A7, T7H, Steyr, and the 70 mining dump truck.

When repairing WG9100520034, the following parts usually need to be checked or replaced simultaneously:

1. Spring Pin: Model such as WG9100520065, this is a key pin that passes through the center of the hanger and secures the leaf spring. Wear will cause play.

2. Spring Bushing: A rubber or polyurethane sleeve press-fitted into the leaf spring hole to prevent direct wear between the spring pin and the leaf spring.

3. Hanger Bushing: A protective lining inside the hanger body hole.

4. Linkage Fasteners: Includes high-strength bolts and nuts securing the hanger to the frame, as well as anti-loosening washers.

5. U-Bolts: Check if the U-bolts on the front leaf spring are loose. Loosening can cause front axle displacement, exacerbating hanger damage.
