The Muncie SH8 Series Power Take-Off, part number SH8B-U6807-A1TX or SH8BU6807A1TX, is an air-shift-only PTO built for high-torque truck applications. Its integral air shift design keeps the air cylinder fully enclosed, eliminating exposed components on the housing. The 8-bolt cast iron housing simplifies mounting and delivers the structural strength demanded by heavy-duty service. With 17 input gear sets available, this SH8 Series unit fits most popular transmission configurations, while 12 output shaft options accommodate the widest range of pump types. Five speed ratios let you match output to the application. Intermittent torque ratings across the five speed ratios range from 325 to 400 lb-ft at 1,000 RPM. Call us to confirm proper fit for your transmission and pump combination.
