Sinotruk HOWO Shift Support Rod Ball Head
The specific model number of this part is WG2229210041.

Detailed Analysis and Maintenance Recommendations:

1. Part Name & Function

• Name: Gear Shift Rod Ball Head Assembly

• Main Function: This is a key component connecting the transmission shift lever to the cab control mechanism. Its primary role is to transmit the force from the driver operating the shift lever in the cab, moving the shift fork shaft inside the transmission to achieve gear changes. The ball head design allows flexible rotation within a certain angle range, accommodating vehicle vibrations and installation tolerances.

2. Applicable Vehicle Models & System

• Applicable Vehicles: Sinotruk HOWO series heavy-duty trucks, including but not limited to HOWO T7H, T5G, TX, and other models.

• System: Transmission Control System

• Specific Location: Typically installed on the top cover or side of the transmission. One end connects to the shift cable or linkage from the cab, while the other end fits into the shift rocker arm or fork shaft support seat (such as the fork shaft support seat you previously inquired about) inside the transmission housing.

3. Purchasing & Maintenance Recommendations

• Parts Matching: The part number WG2229210041 is an original Sinotruk genuine part number (or a number from a major OEM supplier). When purchasing a replacement, ensure that this number precisely matches your specific vehicle model and transmission type. Different transmissions (e.g., HW series, HW19710/19712, etc.) may have variations in shift support rod length and ball head specifications.
