The Muncie SH8D-S6812-P1CX or SH8DS6812P1CX is an 8-bolt cast iron housing power take-off from the Muncie SH8 Series, built specifically for high-torque air-shift-only applications. Positioned between the TG and 82 Series, it bridges demanding duty cycles where a mechanical-shift unit falls short. The integral air shift design keeps the air cylinder fully enclosed inside the housing, eliminating exposed components. With 17 input gear sets, it fits most popular transmissions, and 12 output shaft options cover the majority of pump types in service. Five available speed ratios let you match PTO output to the driven equipment. Intermittent torque ratings run up to 400 lb-ft depending on ratio selected. Call us to confirm proper fit for your specific transmission and pump combination.
