This gearbox is designed for plastic extrusion machine. It meet JB/T9040-1999 standard. The gear is made of high-strength alloy steel and hardened by carburizing and quenching. The accuracy of grinding teeth is higher than Level 6 and the hardness is HRC 54-62. In the front of output shaft,we assemble a thrust bearing with high safety factor to bear the extrusion pressure of screw.

Steps to Replace a Faulty Gearbox in an Automobile
Replacing a faulty gearbox in an automobile is a complex task that requires proper tools, skills, and safety precautions. Here are the general steps involved in the process:
- Prepare the Vehicle: Park the vehicle on a flat surface and engage the parking brake. Disconnect the battery to ensure safety during the procedure.
- Drain Fluids: Drain the transmission fluid from the old gearbox into a suitable container.
- Disconnect Components: Remove any components obstructing access to the gearbox, such as the driveshaft, exhaust system, and linkage.
- Suspend the Engine: If necessary, use an engine hoist or support to suspend the engine safely.
- Support the Gearbox: Use a transmission jack to support the weight of the gearbox.
- Remove Gearbox: Detach the gearbox from the engine by removing bolts and disconnecting the clutch or torque converter.
- Install New Gearbox: Position the new gearbox onto the engine and secure it in place with bolts.
- Reconnect Components: Reattach the driveshaft, exhaust system, and linkage that were disconnected earlier.
- Refill Fluids: Fill the new gearbox with the appropriate transmission fluid according to the manufacturer’s specifications.
- Lower Engine: Carefully lower the engine back into its original position if it was suspended.
- Test and Adjust: Start the vehicle and test the new gearbox for proper operation. Check for any leaks, unusual noises, or gear shifting issues.
- Final Check: Double-check all connections and ensure that all components are properly secured.
- Dispose of Old Fluid: Dispose of the old transmission fluid safely and responsibly.
- Dispose of Old Gearbox: Properly dispose of the old gearbox according to local regulations.
It’s important to note that gearbox replacement can vary significantly depending on the vehicle’s make and model. It’s recommended to consult the vehicle’s service manual or seek professional assistance if you’re not experienced in automotive repair.
