The Muncie SH8B-S6812-P1BX (also referenced as SH8BS6812P1BX) is a power take-off from Muncie's SH Series, built specifically for high-torque, air-shift-only applications. The integral air shift design eliminates an exposed external air cylinder, keeping the unit compact on the transmission. An 8-bolt cast iron housing delivers strength with straightforward mounting. At speed ratio 05 or 07, intermittent torque reaches 400 lb-ft (542 Nm) at 1,000 RPM; continuous torque is rated at 280 lb-ft (379 Nm). Seventeen input gear sets cover most popular transmission configurations, and 12 output shaft options match most common pump types. Five available speed ratios give the flexibility to match pump requirements precisely. Call us to confirm proper fit for your application.
