The EX Drive power take-off shaft extension from Muncie Power Products is designed to fit Allison 3000 and 4000 Series transmissions. The shaft extension replaces the drivetrain, allowing for direct mounting of large gear or piston pumps while reducing installation time. Its minimized housing diameter allows for installation in tight spaces. Providing maximum torque from the power take-off, the shaft extension is available for both clutch-shift and constant-drive PTOs. A welded tube housing and clamping bracket create a flexible design that can be adapted to fit numerous applications. Four output options (S.A.E. B, BB, C and DIN 5462) are available. 800/367-7867; www.munciepower.com.
