The Muncie SH8D-S6812-P3KX or SH8DS6812P3KX is an 8-bolt, air-shift-only power take-off from Muncie's SH8 Series, positioned between the TG and 82 Series for high-torque hydraulic applications. The integral air shift design keeps the air cylinder internal, eliminating exposed external components. Across its five available speed ratios, intermittent torque ratings reach 400 ft-lb (542 Nm) at the 05 and 07 speed ratios, stepping down to 375 ft-lb (508 Nm) at ratio 09 and 325 ft-lb (441 Nm) at ratios 12 and 13. The cast iron housing accepts 17 input gear sets, covering most popular transmission configurations, while 12 output shaft options accommodate the most common hydraulic pump types.
