The Muncie SH8D-S6809-A1PX or SH8DS6809A1PX is an SH8 Series power take-off built for high-torque applications where a compact, air-shift-only unit is required. The integral air shift design keeps all actuation internal, eliminating the exposed air cylinder found on older PTO designs. The 8-bolt cast iron housing mounts securely and accommodates 17 input gear sets, covering most popular transmission configurations. Five available speed ratios let you match output speed to the driven equipment, and 12 output shaft options mean this unit pairs with most common pump types. Torque ratings vary by speed ratio: speed ratio 05 and 07 carry an intermittent rating of 400 lb-ft (542 Nm) and a continuous rating of 280 lb-ft (379 Nm). Sold by Pro Gear and Transmission.
