How to Maintain and Service the Power Take – Off (PTO) Box of a Concrete Pump Truck

● The gear oil viscosity grade used for the power take-off (PTO) box is SAE 90 API GL-4 transmission oil (Shell VG150 gear oil is filled at the factory); it is required to replace the oil every 500 hours of pumping or every six months.

● The lubricating oil level must not exceed the liquid level of the oil level port; otherwise, it will cause abnormal heating of the PTO box, damage the cylinder seals of the input and output shafts, and affect the lubrication effect.

● It is required to inspect the connection bolts of the PTO box and the bracket bolts once a week to prevent damage to the PTO box caused by increased vibration frequency of the transmission shaft due to loose bolts!
