Before installation, ensure the gearbox is completely disassembled and cleaned to remove any debris or wear particles that may affect the synchronizer’s performance. Verify that the 1296-333-045-GP synchronizer cone ring matches the original part dimensions (refer to technical specs below) to guarantee a precise fit with your Sinotruk HOWO transmission system.
Use proper torque tools when securing the cone ring to avoid over-tightening, which can cause material deformation. Check the mating surface of the gear and cone ring for signs of excessive wear; replace any damaged components simultaneously to extend the transmission’s service life.
After installation, conduct a test run to confirm smooth gear shifting without grinding or hesitation. For optimal results, we recommend installation by a certified heavy-duty truck technician familiar with Sinotruk HOWO systems. Always refer to the vehicle’s official service manual for additional model-specific guidelines.
