The Muncie SH6F-F8407-A3PX (also referenced as SH6FF8407A3PX) is a 6-bolt, air-shift-only power take-off from Muncie Power Products' SH Series, designed for high-torque applications that fall between the TG and 82 Series. The integral air shift design keeps the air cylinder enclosed within the housing, which protects it from road debris and simplifies installation. The 6-bolt cast iron housing mounts solidly to the transmission, and the SH Series platform supports 17 input gear sets and 12 output shaft options, covering most popular transmissions and pump types. Five available speed ratios let the SH Series match a range of drive requirements. Rated at up to 400 ft-lb intermittent torque and 280 ft-lb continuous torque at speed ratio 05 and 07.
