06TA6176 Muncie Extended Shaft Assembly

The Muncie extended shaft assembly, part number 06TA6176, is an SAE "B" shaft with a 7/8"-13-tooth spline and an overall length of 19.7 inches, rated for use with the 3000 standard configuration. It is part of Muncie's EX Drive system, designed for Allison 3000 and 4000 series transmissions equipped with a retarder or rear-mounted cooler. The EX Drive eliminates separate driveline installations by allowing large gear or piston pumps to mount directly to the PTO output. The wet spline design extends spline service life, and the three-piece shaft construction simplifies assembly. Compatible with Muncie's A20, A30, A40, A50, and CS40/41 PTO families. Call us to confirm proper fit for your transmission and PTO combination.

Additional Information

The Muncie EX Drive shaft extension system is designed specifically for Allison 3000 and 4000 series transmissions fitted with a retarder or cooler, where conventional driveline or front engine drive installations are impractical. Part number 06TA6176 is the SAE "B" shaft variant from Muncie's service parts document SP18-04 (Titan EX Drive). The three-piece shaft design reduces lead time and simplifies assembly compared to earlier configurations. The steel housing and wet spline design work together to handle direct-mounted gear or piston pump loads without a separate driveline. Available for both clutch shift and constant drive PTOs across compatible Muncie families.
