LEMFORDER 35638 01 BUSH, SPRING SHACKLE

Lemforder 35638 01 Bush, Spring Shackle

The 35638 01 is a high‑performance bush and spring shackle designed for the rear suspension of commercial vehicles. It serves as a critical component that connects the leaf springs to the vehicle chassis while allowing controlled movement and damping during operation.

Key Functionalities

• Spring Support: Provides secure attachment points for leaf springs, ensuring proper load distribution across the axle.
• Controlled Flexibility: The bush material allows a limited amount of flex, which helps absorb road shocks and reduces vibration transmitted to the chassis.
• Durability: Engineered to withstand repeated compression cycles without significant wear or deformation.

Material Composition

The shackle is constructed from a high‑strength alloy steel core, encased in a resilient polymer bush. This combination offers the following benefits:

• Corrosion Resistance: The polymer coating protects the metal from rust and environmental degradation.
• Low Friction: The bush surface reduces wear on adjacent components, extending overall suspension life.
• Heat Dissipation: The alloy core efficiently dissipates heat generated during heavy load conditions.

Compatibility and Applications

The 35638 01 is specifically engineered for the rear axle of certain commercial trucks, particularly those in the IVECO Daily series. It fits models equipped with:

• 2.8L, 2.3L, or 3L engines.
• Platform or chassis configurations that use leaf spring suspension.
• Both van and cargo truck variants within the Daily III range.

Installation Guidelines

1. Preparation: Clean all mating surfaces to remove grease, rust, or debris. Inspect the leaf springs for damage before installation.
2. Alignment: Position the shackle so that its mounting holes align precisely with the chassis brackets and spring attachment points.
3. Tightening Sequence: Use a torque wrench to tighten bolts in a cross‑pattern sequence, ensuring even load distribution. Follow manufacturer torque specifications for optimal performance.
4. Verification: After installation, perform a visual inspection and a gentle compression test to confirm that the bush flexes correctly without binding.

Maintenance Tips

• Regularly inspect for signs of wear such as cracks in the polymer bush or metal fatigue on the shackle body.
• Keep the mounting area free from oil and dirt; apply a light coat of anti‑rust spray if operating in harsh environments.
• Replace the component promptly if any deformation is observed, as this can compromise suspension integrity.

Benefits Over Conventional Bushes

The 35638 01 offers several advantages compared to standard bush assemblies:

• Enhanced Load Capacity: The alloy core can handle higher compression forces, making it suitable for heavy‑duty applications.
• Improved Ride Comfort: Controlled flex in the polymer bush reduces vibration and improves passenger comfort.
• Extended Service Life: Combined material properties reduce wear rates, leading to longer intervals between replacements.

Conclusion

The Lemforder 35638 01 Bush, Spring Shackle is a specialized suspension component that delivers reliable performance for commercial vehicles requiring robust leaf spring support. Its thoughtful design—melding alloy strength with polymer resilience—ensures durability, safety, and comfort across demanding operating conditions.
