The Muncie SH Series power take-off, part number SH8S-S6812-A1EX or SH8SS6812A1EX, is an air-shift-only PTO engineered for high-torque applications. Its integral air shift design keeps the air cylinder fully enclosed within the housing, eliminating exposed external components. The 8-bolt cast iron housing provides a strong, straightforward mounting interface. With 17 input gear set options, this unit covers most popular transmission bolt patterns. Five speed ratios let you match output to your hydraulic system, and 12 output shaft configurations fit most pump types. Torque ratings vary by speed ratio, reaching up to 400 lb-ft intermittent and 280 lb-ft continuous at speed ratios 05 and 07. Call us to confirm the right configuration for your transmission and pump.
