The Muncie SH8D-S6812-P3EX or SH8DS6812P3EX is an 8-bolt, air-shift-only power take-off from Muncie's SH Series, designed to fill the torque gap between the TG and 82 Series. The integral air shift design keeps the air cylinder fully enclosed within the housing, eliminating exposed components. The 8-bolt cast iron housing simplifies mounting and handles demanding duty cycles. With 17 available input gear sets, this PTO fits most popular heavy-duty transmissions, while 12 output shaft options cover the widest range of pump types. Five speed ratios let you match output to your hydraulic system requirements. Intermittent torque ratings reach 400 ft-lb at speed ratios 05 and 07. Call us to confirm proper fit for your specific transmission and pump configuration.
