The PTO Shaft Extension is an exclusive, patented Muncie product that allows for direct coupling large displacement pumps on Allison "World" automatic transmissions. Where envelope space around the PTO aperture is limited, the PTO Shaft Extension moves the pump-mounting flange to the back of the transmission for easy installation. Models are available for both Clutch Shift and Constant Drive Muncie PTOs.

* Due to the added weight at the back of the transmission it is required that the transmission be equipped with a rear support as provided by the vehicle manufacturer. PTO Shaft Extension assemblies cannot be used on transmissions with retarders or rear mounted oil coolers.
