The Muncie SH8D-S6812-A1ZX or SH8DS6812A1ZX is an SH Series power take-off built specifically for high-torque, air-shift-only applications. It mounts via an 8-bolt cast iron housing and uses an integral air shift design with no exposed air cylinder. Buyers can choose from 17 input gear sets to match most popular transmission configurations, and 12 output shaft options to suit common hydraulic pump types. Five speed ratios are available across the series, with intermittent torque ratings reaching 400 lb-ft and continuous ratings up to 280 lb-ft at the lower speed ratios. Designed to bridge the gap between lighter and heavier PTO series, the SH8D fills demanding duty cycles where a standard-duty unit falls short. Call us to confirm proper fit for your application.
