AZ0700290010 Sinotruk Howo 371 Truck HW19710 Gearbox

High Torque Capacity: The HW19710 is specifically designed to handle the high torque output of modern heavy-duty diesel engines (typically in the range of 1750-2100 Nm), making it perfectly suited for the Howo 371’s requirements.
10-Speed Configuration: This transmission offers 10 forward speeds and 2 reverse speeds. This wide ratio spread provides:
Excellent startability and gradeability in low gears.

Optimal fuel efficiency at cruising speeds utilizing the top direct drive (1:1) or overdrive gears.
Flexibility to match varying load and terrain conditions.
Robust Construction: Built to Sinotruk’s stringent standards for heavy-duty applications, the HW19710 features a rugged casing, high-strength gears, and bearings designed for maximum durability and long service life under harsh operating conditions.

Double H Shift Pattern: Features a common and intuitive “H” pattern shifter, allowing drivers to easily navigate through the gear range. The splitter function (typically activated via a thumb switch on the gear lever) efficiently manages the range change between low and high ratios.
Synchronized Design: Key forward gears are synchronized, enabling smoother and faster shifts, reducing driver fatigue, and minimizing driveline shock during gear changes.
Dual-Countershaft Design: Like many heavy-duty transmissions, the HW19710 utilizes a dual-countershaft design. This configuration enhances torque capacity, improves gear mesh strength, and contributes to overall compactness and reliability.

Wide Application: Proven in various Sinotruk HOWO models (like the 371, ZZ3257, and others), it is a trusted transmission for dump trucks, tractor heads, mixers, and other vocational chassis requiring robust power transfer.
