Genuine Sinotruk Howo T7H & SITRAK ABS Pole Ring - Part No. WG7117349041

Genuine Sinotruk Howo T7H & SITRAK ABS Pole Ring - Part No. WG7117349041

The WG7117349041 ABS Ring (also referred to as an Exciter Ring or Pulse Ring) is a critical safety component for the heavy-duty braking systems of Sinotruk Howo T7H and SITRAK series. This high-precision ring provides constant wheel speed feedback to the ABS control unit, ensuring maximum stability and preventing wheel lock-up during emergency braking maneuvers.

Technical Specifications:
Official Name: ABS Pole Ring / Sensor Wheel
Part Number: WG7117349041
Main Application: Sinotruk Howo T7H, SITRAK C7H, SITRAK G7 
Material: High-grade forged steel with anti-corrosion coating.
Tooth Profile: Precision-milled teeth for accurate magnetic pulse generation.
Hardness: Heat-treated for resistance against road debris and thermal expansion.
Dimensions: Exact OEM specification for a seamless interference fit.

Best Practices for Installing the WG7117349041 ABS Ring:
Preparation: Before fitting, thoroughly clean the wheel hub mounting surface. Any rust or unevenness can cause the ring to "wobble," leading to intermittent ABS signals.
Heat Fitting (Recommended): To ensure a secure and even fit, it is recommended to heat the ABS ring slightly (do not exceed 180°C) before pressing it onto the hub. This allows for thermal expansion and a tighter grip once cooled.
Avoid Direct Hammering: Never strike the teeth of the WG7117349041 directly with a metal hammer. Use a wooden block or a professional press tool to apply even pressure across the circumference.
Sensor Gap Calibration: Once the ring is seated, check the air gap between the ABS sensor and the ring teeth. For Sinotruk T7H/SITRAK models, ensure the gap falls within the manufacturer's specified range (typically 0.5mm - 1.5mm).
