WG2211040101 1st gear is finely made of high-quality alloy structural steel. Through carburizing, quenching and precision gear grinding processes, it features high tooth surface hardness, excellent toughness, superior wear and impact resistance, and is not prone to tooth chipping or deformation under heavy loads.
It boasts high gear profile accuracy with tight meshing fit, delivering stable and quiet transmission as well as strong starting torque capacity.
Manufactured to original factory standard dimensions, it is compatible with Sinotruk HOWO and Sitrak series gearboxes for direct interchange without any modification.
The internal splines are precisely machined for firm assembly without looseness. Suitable for harsh working conditions such as long-distance freight and construction site heavy loads, it is durable and reliable, serving as a high-quality part for maintenance and replacement.
