hino brake drum 43513-4100

The hino brake drum 43513-4100 model is designed for heavy-duty Hino truck series, offering robust braking performance under the most demanding service conditions. Produced by Xingtai SNT Auto Parts Factory, this drum combines advanced material processing with stringent dimensional control.

Material Composition and Casting Quality

Brake drum 43513-4100 uses high-graphite grey iron with additives to enhance thermal fatigue resistance. Our foundry employs low-pressure casting to reduce gas entrapment and porosity. The casting configuration ensures uniform cooling rates, reducing internal stresses that can lead to premature cracking.

Machining Precision and Surface Treatment

Following casting, drums progress through:

1. Rough turning: Establishing inner diameter and mounting flange to within ±0.10 mm.

2. Finish grinding: Achieving concentricity within ±0.03 mm and surface roughness (Ra) below 2.0 µm.

3. Phosphate coating: Providing corrosion protection and improved break-in characteristics.

Every machining operation is monitored via in-line laser measurement to maintain consistency across production batches.

Quality Verification

The 43513-4100 drums undergo multi-point inspections:

• Dynamic balancing at operational speeds.

• Hardness testing to confirm compliance with the Hino-specified Rockwell range.

• Non-destructive testing using ultrasonic transducers to detect internal flaws.

Certificates of conformity accompany each batch, ensuring traceability from raw material to finished component.

Maintenance and Resurfacing

Designed for extended operational cycles, the 43513-4100 can be safely re-machined down to the specified minimum bore diameter, extending service life. Our technical guide outlines recommended service intervals—typically aligned with brake shoe replacement—and provides step-by-step resurfacing procedures to maintain optimal braking performance.
