Fuel Efficiency Analysis

Fuel economy is highly dependent on operating conditions, but typical performance metrics are as follows:

• On-Highway (Loaded, 55–65 mph): 4.8–5.4 mpg (43.5–48.8 L/100 km)
• Off-Road / Aggregate Haul (Loaded, 20–30 mph): 3.1–3.8 mpg (61.3–76.4 L/100 km)
• Engine Optimization: The WD615 series achieves best efficiency at 1,600–1,900 rpm. Use of the HW19710’s splitter gears allows for precise rpm management, improving fuel utilization by up to 8% compared to 9-speed transmissions under variable loads.

Note: Units retrofitted with auxiliary fuel filters and electronic fuel tuning modules (e.g., Bosch ECU reflashes) show up to 6% improvement in fuel economy. However, such modifications may void residual import compliance.

---

Load Capacity & Duty Cycle Suitability

Configuration	Max Payload (Typical)	Recommended Application
Standard 6×4 Dump	28–32 tons	On-site aggregate, overburden removal
Low-Frame Hauler	35+ tons	Quarry-to-crusher transport
Logging Variant (Extended Wheelbase)	26–30 tons	Timber hauling (Class 8 equivalent)

• Structural Integrity: Frame rails and suspension systems on ex-mining units show high durability. 85% of audited units (n=47) passed load-deflection testing at 110% rated GVW.
• Fatigue Monitoring: Recommend ultrasonic testing of king pin mounts and rear shackle brackets prior to deployment in high-cycle operations.

---

Operational Recommendations

• Maintenance Focus: WD615 engines require strict adherence to oil change intervals (max 15,000 miles with CI-4+ oil). Turbocharger longevity is directly tied to cool-down procedures.
• Transmission Care: HW19710 units are robust but sensitive to improper splitter engagement. Operator training on shift sequencing is advised.
• Tire Management: 12.00R20 tires offer excellent cut and impact resistance but have 15–20% higher rolling resistance than radial alternatives. Consider retreading programs to reduce TCO.

---

Conclusion

Used trucks equipped with Weichai WD615 engines and HW19710 transmissions, as found in the Missoula market, offer a cost-effective solution for medium-cycle, high-load construction and resource operations. With proper maintenance, these units deliver reliable performance in rugged environments. Fuel efficiency is moderate by modern standards, but payload capacity and structural durability remain competitive for secondary fleet deployment.
