Description
The Muncie SH8D-S6809-A1EX or SH8DS6809A1EX is an air-shift power take-off from Muncie’s SH Series, designed to bridge the gap between lighter and heavier PTO lines for high-torque truck applications. The integral air shift mechanism keeps the air cylinder fully enclosed within the housing, eliminating external cylinder exposure. The 8-bolt cast iron housing mounts securely to most popular transmissions, with 17 input gear set options and 12 output shaft configurations covering a wide range of hydraulic pump interfaces. Five speed ratios are available; intermittent torque ratings reach 400 lb.ft. (542 Nm) at the two highest-ratio positions. Call us to confirm the correct ratio and output shaft configuration for your specific transmission and pump setup.
