PC78 Komatsu Excavator Final Drive 21W-60-41201

Excavator Travel Motor Assy PC78 Final Drive 21W-60-41202,21W-60-41201

Final drive 21W-60-41201 is fitting on Komatsu PC78UU-6 excvavators. The final drive consists of a walking motor and a decelerating part. There are two final drives on the machine, left and right, which directly drive the track to enable the machine to move forward, backward and turn. The Travel motor is very similar in structure to the pump.As the power output device of the hydraulic system, it does not push the hydraulic oil like the pump, but is pushed by the high-pressure hydraulic oil and produces torque and continuous rotary motion. The driving motor is a straight - axis plunger motor.The plunger motor produces torque by applying pressure to the plunger part of the cylinder block.In the straight shaft structure, the motor drive shaft and the cylinder block are centered from the same axis.The pressure at the plunger end causes a counterforce on the swash plate that drives the cylinder block and the motor shaft to rotate. In use, if the oil inlet and the oil outlet are exchanged, the motion is opposite to the above, and the driving shaft rotates in reverse. We can supplied original/used/Replaced Excavator final drive and travel motor send to all over the world .Hydraulic Pump and spare parts can provide.
