Shacman Delong F3000 X3000 M3000 Rear Brake Drum DZ9112340006

The DZ9112340006 Rear Brake Drum is a fundamental component of the heavy truck air braking system. Installed directly onto the rear wheel hub assembly, this Shacman brake drum provides a smooth, wear-resistant cylindrical friction surface against which the brake linings press during pneumatic brake application.

Manufactured in ISO9001-certified facilities using high-tensile cast iron, the DZ9112340006 brake drum is engineered for high thermal absorption and rapid heat dissipation to resist brake fade under continuous downhill braking. Replacing a cracked, out-of-round, or heavily grooved unit with a new DZ9112340006 drum restores maximum braking torque, reduces stopping distances, and prevents premature wear on brake linings.

Technical Specifications

Key Features and Benefits

• High Thermal Capacity: Cast iron metallurgy resists high temperatures, preventing heat checking, warping, and thermal distortion during heavy hauling.

• Precision Machined Friction Surface: Dynamically balanced surface ensures uniform contact with brake shoes to eliminate pedal pulsation and wheel chatter.

• High Structural Strength: Reinforced rim and wall design withstands intense pneumatic actuation forces and heavy axle loads.

• Direct OEM Fitment: Manufactured strictly to factory specification DZ9112340006 for exact bolt-circle and hub pilot alignment.

Compatible Vehicle Applications

This DZ9112340006 rear brake drum is widely used on commercial heavy-duty transport platforms:

• Shacman Truck Series: Shacman Delong F3000, X3000, and M3000 tractor heads, heavy dump trucks, concrete mixers, and cargo trucks.

• Sinotruk Series: Compatible Howo heavy commercial platforms using standard 68 kg rear brake drums.

Symptoms of a Damaged Rear Brake Drum

Fleet mechanics and technicians should inspect or replace the DZ9112340006 brake drum when observing:

• Severe steering wheel or chassis vibration when depressing the brake pedal (out-of-round condition).

• Deep scoring grooves, heat cracks, or blue discoloration on the inner braking surface.

• Reduced braking performance and extended stopping distances under loaded conditions.

• Squealing or grinding noises caused by worn friction surfaces or uneven drum expansion.

Packaging and Delivery Details

• Heavy-Duty Protective Packaging: Secured in heavy export carton boxes (50x50x30 cm) and palletized to support the 68 kg unit weight and prevent transport damage.

• Flexible Shipping Schedules: Available for air freight for urgent repairs or sea container shipping for bulk distributor orders.

• Fulfillment Time: Standard order processing and dispatch within 7 to 30 days depending on order volume.

Frequently Asked Questions (FAQ)

Q1: What causes brake drums like the DZ9112340006 to crack or warp?

A: Excessive heat buildup from prolonged braking, riding the brakes on long downgrades, or rapid cooling after extreme thermal exposure can cause thermal cracking and deformation.

Q2: Should brake drums be replaced in pairs across the same axle?

A: Yes, replacing brake drums in pairs across the same axle is strongly recommended to maintain even braking balance and prevent the vehicle from pulling to one side.
