WG9231342006 420x185mm Howo Brake Drum Rear Axle Parts For HC16 AC16

Product Specification

SINOTRUK HOWO Rear Brake Drum WG9231342006 | 420x185mm Heavy-Duty Component for HC16 AC16 Axles

Product Overview

The WG9231342006 Brake Drum is a premium-grade, heavy-duty replacement component specifically engineered for SINOTRUK HOWO and Steyr series trucks. Designed for 16-ton HC16 and AC16 wheel reduction axles, this brake drum is essential for providing the extreme braking torque required by mining tippers, heavy loaders, and long-haul logistics vehicles.

Manufactured from high-carbon HT250 / G3000 Gray Cast Iron, our WG9231342006 model features a reinforced wall design for superior heat absorption. This ensures that even under maximum payload and frequent braking, the drum maintains structural integrity and prevents "brake fade." Each unit is CNC-machined to exacting tolerances, offering a perfect fit and OEM-matching reliability for international fleet maintenance.

Key Benefits

Reinforced Heavy-Duty Design: Specifically built for 16-ton axles, featuring increased thickness to withstand the mechanical stress of mining and construction environments.

Superior Thermal Stability: Advanced metallurgy dissipates heat rapidly, significantly reducing the risk of thermal cracking and "blue spots."

Precision Dynamic Balancing: Each drum undergoes factory-balancing to eliminate vibrations at high speeds, extending the life of hub seals and wheel bearings.

High Friction Consistency: The fine-lathed friction surface promotes a rapid "bedding-in" process with new brake shoes, providing maximum stopping power from day one.

ISO/IATF 16949 Certified: Produced under strict quality management systems to meet or exceed OEM service life standards.

Frequently Asked Questions (FAQ)

1. Which axle systems is the WG9231342006 Brake Drum compatible with?

The WG9231342006 Brake Drum is specifically engineered for Sinotruk HOWO AC16 heavy-duty reduction axles. These are commonly found on 6x4 and 8x4 dump trucks, mining trucks, and specialized engineering vehicles. Because the AC16 axle is designed for extreme loads, this drum features a reinforced casting. We recommend verifying the 10-hole mounting pattern and the specific flange thickness to ensure a perfect fit for your AC16 hub assembly.

2. How does the WG9231342006 perform under high-tonnage braking?

Designed for mining and construction environments, the WG9231342006 is manufactured from alloyed G3000/G3500 Grey Iron. This material provides superior thermal fatigue resistance, which is critical when descending steep grades with a full payload. The advanced metallurgy allows the drum to maintain structural integrity and prevent "bell-mouthing" (expansion) even when internal temperatures exceed normal operating ranges, ensuring consistent braking torque.

3. Is the WG9231342006 Brake Drum dynamically balanced for high-speed stability?

Yes, every WG9231342006 unit undergoes strict dynamic balancing before leaving the factory. For heavy-duty HOWO trucks, an unbalanced drum can lead to severe vibration that damages ABS sensors, wheel seals, and tires. Our precision balancing process ensures smooth rotation and uniform wear across the brake linings, which significantly extends the maintenance intervals and reduces vehicle downtime.

4. What is the Maximum Diameter (Max Dia) for the WG9231342006?

Safety is paramount in heavy-duty hauling. The Maximum Diameter (Max Dia)—the safety wear limit—is cast or stamped on the outer edge of the WG9231342006. During routine maintenance of your AC16 axle, the inner diameter should be measured using a drum micrometer. If the diameter has reached the limit, or if you find "blue spots" indicating localized overheating, the drum must be replaced to prevent catastrophic failure under high-pressure braking.
