WG2229100043 Fork Support Pin （重：180g 外径：1.8cm 高：5.7cm）

As a core supporting component for the range gear shift fork mechanism of Sinotruk gearboxes, this part functions in positioning, supporting and rotational guiding, ensuring the shift fork completes high and low gear switching steadily and flexibly.

Adopting integral precision turning technology, it features tightly controlled dimensional tolerances, high coaxiality and reliable precision.

Made of high-density wear-resistant material, it resists eccentric wear and looseness failure even under long-term high-frequency swinging.

Fully compliant with original factory shape and parameters, it allows non-destructive in-situ replacement for original vehicles. Compatible with mainstream gearboxes of heavy-duty trucks like Howo, it adapts to long-distance heavy haulage and complex mountain working conditions. It firmly supports the transmission structure and avoids various malfunctions caused by shifting stagnation and excessive clearance.

This shift fork support pin is precisely forged from high-quality alloy steel with standard specifications. Its outer diameter is 1.8cm, height 5.7cm, and net weight 180g.

Subjected to overall quenching and tempering treatment, it features uniform hardness and excellent toughness, with outstanding compression resistance, bending resistance and impact resistance without deformation.

The shaft body is precision ground and polished with a smooth and wear-resistant surface and precise fitting clearance, ensuring smooth reciprocating operation without jamming.

It possesses excellent fatigue resistance, rust and corrosion resistance, capable of withstanding long-term stress from frequent gear shifts and heavy-duty bumping impacts of the gearbox.

With standard original factory dimensions and good interchangeability, it fits firmly after installation, effectively reducing mechanical looseness and abnormal noise, and extending the service life of the gear shifting assembly.
