Doosan 300506-00988 is the cab air conditioner and heater blower motor with fan wheel and housing flange. It is used on Doosan DX series excavators (DX140W to DX340LC). This aftermarket version has the same mounting and electrical connector as the original, so it plugs in and bolts on where the old one came off.
The same part is also sold as Doosan K1002206.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

All of these numbers are the same part.
No air from the vents
If the fan control and fuse are fine but no air comes from the cab vents at any speed, the blower motor has stopped.
Noise and vibration
A squeal, rattle or wobble from behind the vents means worn bearings or a damaged fan wheel. Replace the blower before it seizes.
Weak airflow or only some speeds
Worn brushes cut the airflow. If only some speeds work, check the blower resistor as well.
Fitting tips
Disconnect the battery, remove the blower cover or cab panel, unplug and unbolt the old blower, and fit the new one the same way round. Check every fan speed before refitting the trim.
