What If the VOLVO Excavator Motor Speed Is Low? How to Fix It?

When the Volvo excavator suddenly has a low motor speed situation, what should we do? How to fix Volvo excavator motor?(travel motor )As an excavator lover, I will analyze the reasons first.

I think the Volvo excavator may have low motor speed for the following reasons:

1. The internal leakage is increased due to loosening of the fastening bolts of the piston motor base, then creates a decrease in the excavator motor speed.

2. Due to the failure of the flow control valve, pressure regulating valve, hydraulic pump and other components, the flow received by the piston motor does not meet the requirements, resulting in a low excavator motor speed situation.

3. The sliding surface of the piston motor is seriously worn, causing the hydraulic oil to overflow from the high side to the low side, resulting in low motor speed.

Correspondingly, the solution is as follows:

1. Fasten the pedestal bolts according to the specified torque.

2. Check whether the flow of the piston motor inlet meets the requirements, check whether the parts are faulty, and if necessary, repair in time.

3. Check the wear and tear of the moving parts of the motor for repair or replacement.
