The Muncie SH8D-S6813-E3BX or SH8DS6813E3BX is an SH8 Series air-shift power take-off built for high-torque commercial truck applications. It features an integral air shift design with no exposed air cylinder and an 8-bolt cast iron housing for strength and straightforward mounting. Five speed ratios cover a wide range of output needs, and 17 input gear sets make it compatible with most popular transmissions. Twelve output shaft options accommodate most common hydraulic pump configurations. Intermittent torque ratings reach 400 lb-ft (542 Nm) at the faster speed ratios, stepping down to 325 lb-ft (441 Nm) at the lower ratios. Call us to confirm proper fit for your application.
