The Muncie SH8S-M6512-P3BX or SH8SM6512P3BX is an SH8 Series medium-duty power take-off with an 8-bolt cast iron housing and an integral air shift design that keeps the air cylinder fully enclosed. Five speed ratios and 17 input gear sets give it broad transmission compatibility, covering most popular heavy-duty truck transmissions. Twelve output shaft options let you match it directly to the most common hydraulic pump configurations. Torque ratings vary by speed ratio: at ratios 05 and 07 intermittent torque reaches 400 lb-ft (542 Nm), stepping down to 375 lb-ft (508 Nm) at ratio 09 and 325 lb-ft (441 Nm) at ratios 12 and 13. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
