Description
The Muncie SH8 Series power take-off, part number SH8S-S6812-E1BX or SH8SS6812E1BX, is an air-shift-only PTO built for high-torque applications. Its integral air shift design eliminates an exposed air cylinder, keeping the installation clean and the profile tight. The 8-bolt cast iron housing mounts easily and holds up in demanding service. With 17 input gear sets covering most popular transmissions, 5 available speed ratios, and 12 output shaft options to suit most common pump types, this unit covers a wide range of vocational truck builds. Series torque ratings at intermittent duty reach 400 ft-lb at speed ratios 05 and 07, stepping down to 375 ft-lb at ratio 09 and 325 ft-lb at ratios 12 and 13.
