Muncie TG8F-E8005-P1BX Power Take-Off (PTO)
The Muncie TG8F-E8005-P1BX PTO is an 8-bolt, air-shift power take-off engineered for Eaton Endurant HD and PACCAR TX12 automated transmissions. Part of Muncie Power Products’ proven TG Series, this PTO combines a compact die-cast aluminum housing with a durable three-gear design, making it well suited for vocational trucks that need dependable auxiliary power without excessive weight or installation interference. Muncie specifically lists the TG8F-E80 series for these Eaton/PACCAR transmission applications.
The E8005 configuration uses Muncie’s E80 transmission gear with the 05 internal ratio. In the applicable Eaton Endurant/PACCAR installation, the TG8F-E8005-P1BX operates at approximately 82% of engine speed, with an intermittent rating of 270 lb-ft of torque and 51 HP at 1,000 PTO RPM. Muncie rates the 05 TG Series ratio at 189 lb-ft continuous torque.
The P shift code identifies this configuration as a manual air-shift PTO supplied without the activation kit, while the 1 assembly arrangement designates a right-side, shaft-low configuration. The B output is a 1-1/4-inch round keyed shaft, designed for remote-driven hydraulic pumps or other auxiliary equipment, and the final X indicates no additional special feature option.
For Eaton Endurant and PACCAR applications, Muncie uses a specialized seal-plate gasket rather than a conventional paper gasket. This design accommodates the transmission lubricant and allows installation without the traditional PTO backlash-setting procedure. The application catalog also specifies a stud kit with this PTO configuration.
