The 24508-321 Morbark OEM Drive Coupler is an OEM coupling for Morbark wood processing equipment. Morbark manufactures horizontal grinders, whole tree chippers, and forestry equipment used in land clearing, biomass processing, recycling, and wood waste operations.
Morbark grinders and chippers are diesel-powered machines that subject their drive couplers to severe duty – high torque from large diesel engines, shock loading when the cutting drum encounters dense material, and continuous vibration in dusty, outdoor environments. The coupler must transmit torque reliably while absorbing these forces to protect the gearbox and engine from torsional damage.
The 24508-321 is a direct factory replacement. Follow Morbark’s service procedure for coupler removal and installation, including alignment verification.
