Basic Info

Part No.: WG2229210041 

Product Name: Gearbox Support Rod Assembly 

Applicable Brand: SINOTRUK HOWO, HOHAN, Steyr Heavy Trucks 

Applicable Gearbox: HW series 10/12 speed transmission gearbox 

Core Function: This support rod assembly undertakes the fixing, supporting and vibration buffering work of the gearbox internal shifting control system. It cooperates with the gear shift lever and shift fork rocker block to maintain stable positioning of the shifting mechanism, prevent shifting offset and parts shaking caused by vehicle vibration. It solves common failures such as unstable gear position, easy gear jumping and inaccurate gear selection, greatly improving the overall stability and safety of the gearbox shifting system.

Manufacturing Process

The support rod body adopts high-quality high-rigidity alloy steel integral forging molding, with uniform internal structure and strong toughness. The mounting holes and connecting surfaces are processed by precision CNC machining to ensure zero-error fitting with original gearbox parts. The surface adopts advanced anti-rust, anti-corrosion and wear-resistant treatment to resist long-term vibration friction and harsh environmental erosion. Every finished assembly undergoes strict load-bearing test, dimensional inspection and durability screening before delivery to fully meet OEM assembly standards and heavy-duty working requirements.

Key Features

✅ Exact OEM Standard, Direct Replacement

Standard OE number WG2229210041, fully consistent with original installation size, hole spacing and assembly structure. No drilling, cutting or modification needed, enabling fast and convenient installation, perfectly matching SINOTRUK HW series gearbox models.

✅ High-Strength Forged Body, Super Load-Bearing

Integral forging alloy steel structure enhances overall rigidity and pressure resistance. It can withstand long-term gear shifting impact and vehicle jitter, effectively avoiding bending, deformation and fracture of the support rod, ensuring long-term stable supporting performance.

✅ Stabilize Shifting System, Prevent Gear Jumping

Precision positioning design firmly fixes the shifting control components, eliminates mechanism looseness and displacement caused by vibration. Effectively solves faulty issues like unstable gear position, gear jumping and shifting deviation, making gear selection more accurate and reliable.

✅ Excellent Anti-Vibration & Anti-Fatigue Performance

Professional structural optimization and surface treatment resist frequent vibration and friction during long-distance transportation and heavy-load climbing. Adapt to harsh working conditions of construction sites and mountain roads, reducing gearbox failure rate.

✅ Integrated Complete Assembly, High Practicability

Comes with complete matching accessories as a finished assembly. No need to purchase scattered accessories separately, greatly improving maintenance efficiency and saving overall replacement time and cost for repair workshops.

✅ Strict Full Inspection & Stable Quality

100% dimensional calibration, load-bearing test and surface defect detection before shipment. Each product features stable mechanical performance, high fitting accuracy and consistent quality, suitable for bulk export and fleet long-term use.

✅ Factory Direct Supply, High Cost Performance

Direct factory sales with favorable prices, retaining OEM-level use performance. It is the ideal high-quality aftermarket replacement part for global heavy truck spare parts distributors and maintenance institutions.
