Muncie Power Products, Inc. announced the release of the new A20 Series power take-off (PTO), designed to fit on Allison 3000 and 4000 Series transmissions.

The big changes with this PTO focus on the installation process. The A20 Series PTO features a new rotatable flange with 30 unique, identifiable positions providing flexibility in finding the optimal position when mounting your hydraulic pump.

With these position codes, fleets can choose to order PTOs set to a specific code and have it shipped that way. Alternatively, fleets can have it shipped loose and set the arrangement before, during, or after installing it.

This rotatable flange is independent of the seals — meaning it is adjustable without any concern of damaging the shaft seal. Beyond this unique flange, Muncie focused on other areas to make installation easier. The housing design allows easier access to the mounting bolts and the mounting bolts have been extended to take full advantage of the threads provided on the transmission.

An additional feature with the A20 Series PTO is the option to order one of two tool kits. The tool kit contains a torque wrench (optional), tool bag, and all the tools needed toproperly install the PTO. This tool kit can be ordered as a separate part number.

The A20 Series has a single torque rating for intermittent and continuous dutyapplications of 415 lb.-ft. This PTO is applicable for a number of markets including dump, fire and rescue, refuse, utility, tow and recovery, snow and ice, and bulk hauling, among others.
