The Muncie SH Series power take-off, part number SH8D-S6813-A3KX or SH8DS6813A3KX, is an air-shift-only PTO built for high-torque truck applications. It mounts via an 8-bolt cast iron housing and uses an integral air shift design with no exposed air cylinder. Five speed ratios are available across the series, with intermittent torque ratings up to 400 lb-ft (542 Nm) and continuous torque up to 280 lb-ft (379 Nm) at the highest-rated ratios. Seventeen input gear sets cover most popular transmission applications, and 12 output shaft options accommodate the most common hydraulic pump configurations. Call us to confirm the right ratio and output shaft combination for your specific pump and transmission setup.
