The 46492948 Doosan OEM Drive Coupler is an OEM Bowex-style coupling for Doosan portable air compressor platforms. This curved-jaw coupling with elastomeric spider element connects the diesel engine to the compressor airend in select Doosan portable models.
Doosan Portable Power compressors are designed for construction and industrial jobsite use. The Bowex-style coupling handles engine torque transmission while the spider element dampens firing-pulse vibration. Inspect the spider at every service interval and replace when wear or deformation is present.
The 46492948 is a direct factory replacement. Inspect jaw profiles, install a new spider element, and align per Doosan’s procedure.
