The Muncie SH8 Series Power Take-Off, part number SH8S-U6812-P3ZX or SH8SU6812P3ZX, is an air-shift-only PTO engineered for high-torque applications. The SH Series fills the performance gap between Muncie's TG and 82 Series. Its integral air shift design eliminates any exposed air cylinder, keeping the unit compact and protected. The 8-bolt cast iron housing makes mounting straightforward and provides the structural strength heavy-duty installations demand. With 17 input gear sets, it covers most popular transmission configurations, and 12 output shaft options accommodate a wide range of pump types. Five available speed ratios let you match output to the driven equipment. At speed ratio 05 or 07, intermittent torque reaches 400 lb-ft (542 Nm) at 76 hp.
