The Muncie SH6F-F8412-P1BX or SH6FF8412P1BX is an air-shift-only power take-off from Muncie's SH Series, engineered to handle high-torque truck applications. The integral air shift design keeps the air cylinder fully enclosed, eliminating exposure to road debris and damage. A 6-bolt cast iron housing makes mounting straightforward and provides proven strength. The SH Series supports 17 input gear sets, giving this unit broad transmission compatibility, along with 12 output shaft options to match the most common pump configurations. Five available speed ratios cover a wide range of hydraulic application requirements. At speed ratio 05 or 07, intermittent torque capacity reaches 400 lb-ft (542 Nm) at 1,000 RPM. Call us to confirm proper fit for your transmission and application.
