The 24509-525 Morbark OEM Drive Coupler is an OEM coupling for Morbark forestry and wood processing equipment. Morbark machines including horizontal grinders and whole tree chippers use heavy-duty drive couplers to connect the diesel engine to the processing mechanism through a torsionally flexible element.
Morbark equipment is deployed in land clearing, biomass fuel production, tree removal, and recycling operations. These machines run at high torque with frequent shock loads from the material being processed. The drive coupler is critical for protecting the driveline from these impact forces, and coupler condition should be inspected at every scheduled maintenance interval.
The 24509-525 is a direct factory replacement. Follow Morbark’s service procedure including alignment verification before returning to service.
