WLY 6T120 series truck six-speed transmission power take-off (PTO) 6T120Q-0000 6T120Q-0000A2
FUNCTION
1. Pneumatic Operation, On-Demand Control: Utilizes an axle-based pneumatic control circuit (via a pneumatic valve). The driver activates a switch within the cab; air pressure then drives an internal piston within the PTO unit, ensuring precise engagement between the PTO gear and the gearbox countershaft gear. When not in operation, the unit disengages, achieving zero power consumption.
2. High Torque Transmission Capacity: Specifically engineered to handle the high-torque output of the Wanliyang 6T120 6-speed gearbox. The modular gears undergo a surface carburizing and quenching treatment process, enabling them to withstand the high-impact loads generated during the full-load lifting operations of dump trucks over extended periods, thereby preventing gear damage.
3. Bi-directional/Multi-Interface Expandability: The rear output end typically features a standard 4-hole flange interface or an internal spline interface. This allows for direct bolt-on connection (or connection via a drive shaft) to various hydraulic gear pumps and high-pressure piston pumps.
4. Dual-Plane Robust Sealing: The interface between the PTO housing and the gearbox employs high-grade, oil-resistant, and high-temperature-resistant gaskets and oil seals. This effectively prevents cross-contamination between the gearbox gear oil and the external hydraulic fluid, while also preventing external leakage.
5. Neutral-Gear Power Take-Off (N-PTO): Enables the vehicle to deliver continuous and stable power output while stationary and with the gearbox shifted into neutral. This capability meets the demands of high-frequency operational scenarios, such as stationary unloading for dump trucks, stationary lifting for truck-mounted cranes, and stationary water pumping for sprinkler trucks.

Maintenance and Care Recommendations
1. Strictly Synchronize Oil Changes with the Transmission: The Power Take-Off (PTO) unit lacks an independent lubrication chamber and relies on the transmission's gear oil for splash lubrication. On new vehicles, the lubricant must be changed after the first 5,000 kilometers of operation; subsequently, every 20,000 to 30,000 kilometers, replace the oil-using high-quality heavy-duty gear oil (85W-90)-in conjunction with the transmission oil change.
2. Inspect Mounting Bolts During Every Service: Due to the extreme vibration inherent in heavy-duty dump trucks, the six mounting bolts connecting the PTO to the transmission must be inspected every two weeks or monthly. If these bolts become loose, the gear center distance may shift, leading to severe abnormal noises or even catastrophic damage to the transmission housing.
3. Regularly Inspect Air Lines and Vent Ports: Ensure that the pneumatic control valve and air lines are free of leaks, and verify that the air pressure remains within the standard operating range. Additionally, periodically clean the breather plug located on the top of the PTO housing to prevent internal oil vapors from expanding under heat, which could otherwise lead to oil seal leakage.
4. Hydraulic Pump Drive Shaft Lubrication: If a split-shaft drive connection is utilized, the universal joints (crosses) and splined sleeves of the drive shaft must be fully greased on a quarterly basis to prevent seizing, which can result in abnormal vibrations.
