The Muncie SH8B-S6812-P3KX or SH8BS6812P3KX is a Muncie SH8 Series power take-off built for high-torque applications. It uses an integral air shift design with no exposed air cylinder, mounted in an 8-bolt cast iron housing. With 17 input gear sets available, it covers most popular heavy-duty transmissions, and 12 output shaft options mean it fits a wide range of pump configurations. Five speed ratios give the installer real flexibility in matching PTO output to pump requirements. Intermittent torque ratings reach 400 lb-ft at speed ratios 05 and 07 at 1,000 RPM, stepping down by ratio. Call us to confirm the right speed ratio and output shaft configuration for your application.
