Muncie Power Products released the A20 Series power take-off (PTO), which is designed to fit on Allison 3000 and 4000 Series transmissions.

According to Muncie, the big changes with the PTO focus on the installation process. The company’s goal was to find ways to make it not only easier, but less time consuming.

The A20 Series PTO features a new rotatable flange with 30 unique, identifiable positions that allow for flexibility in finding the optimal position when mounting a hydraulic pump. With these position codes, customers can choose to order their PTO set to a specific code and have it shipped to them that way. Alternatively, Muncie says they can have it shipped loose and set the arrangement before, during or after installing it.

The rotatable flange is independent of the seals, meaning it is easily adjustable without any concern of damaging the shaft seal.

Beyond the flange, Muncie focused on other areas to make installation easier. The housing design allows easier access to the mounting bolts, the company says, and the mounting bolts were extended to take advantage of the threads provided on the transmission.

An additional feature with the A20 Series PTO is the option to order one of two toolkits. Muncie engineers developed and refined a toolkit allowing an installer to have everything need for a PTO installation in one place. The toolkit contains an optional torque wrench, tool bag and all the tools needed to properly install the PTO, according to Muncie.
