Original ZF 12-speed AMT Main Shaft Gear, compatible with ZF 12TX series automatic gearboxes and suitable for heavy-duty trucks such as Sinotruk SITRAK and HOWO equipped with ZF automatic transmissions.<\/div>\n
<\/div>\n
Made of high-strength alloy through carburizing and quenching process, it adopts a full helical gear design with high tooth surface precision, ensuring smooth meshing and a transmission efficiency up to 99.7%.<\/div>\n
<\/div>\n
It features excellent fatigue resistance and wear resistance, resisting tooth breakage and edge chipping under heavy loads while maintaining quiet operation.<\/div>\n
<\/div>\n
With original factory standard dimensions, it perfectly matches the input shaft for direct replacement without modification. Ideal for high-load working conditions including long-distance logistics and engineering heavy haulage, its service life far exceeds that of aftermarket parts.\"\"\"\"<\/div>", "protected": false }, "excerpt": { "rendered": "
1358 302 224 is the core transmission gear of the main box for ZF 12-speed AMT gearbox. It meshes with the input shaft and transmits power to the countershaft gear set.<\/div>\n
<\/div>\n
It is compatible with ZF 12TX2420\/2620\/2621\/2821 and other 12-speed automatic gearboxes, applicable to Sinotruk heavy-duty trucks factory-equipped with ZF automatic transmissions.<\/div>\n
<\/div>\n
With precision ground tooth surfaces and coaxiality within 0.02mm, it adopts surface strengthening treatment for outstanding impact resistance and corrosion resistance.<\/div>\n
<\/div>\n
It effectively avoids faults such as gear jumping, abnormal noise and power interruption.
