The Muncie SH8B-S6812-P1KX or SH8BS6812P1KX is an SH8 Series power take-off built for high-torque air-shift applications. It features an 8-bolt cast iron housing measuring 15.63 in. long x 13.38 in. wide x 11.63 in. tall, with an integral air shift design that eliminates any exposed air cylinder. Five speed ratios are available, with intermittent torque ratings ranging from 325 to 400 lb-ft (441-542 Nm) and intermittent output up to 76 HP (57 kW) at 1,000 RPM depending on ratio selected. Seventeen input gear sets cover most popular transmission mounting configurations, and 12 output shaft options accommodate most common pump types. Call us to confirm the right ratio and output shaft configuration for your specific truck and pump setup.
