The Muncie SH8B-U6812-A1KX or SH8BU6812A1KX is an SH8 Series power take-off built for high-torque applications. The housing is an 8-bolt cast iron design that simplifies mounting and handles demanding duty cycles. An integral air shift mechanism keeps all actuation components inside the unit, eliminating the exposed air cylinder found on conventional air-shift PTOs. Five speed ratios give drivetrain flexibility, while 17 input gear sets cover most popular transmission bolt patterns. Twelve output shaft options let this PTO interface with most common hydraulic pump types. Series torque ratings reach up to 400 ft-lb intermittent and 280 ft-lb continuous at speed ratio 05 and 07. Call us to confirm proper fit for your specific transmission and pump combination.
