New PTO for Allison transmissions

By Mike Brezonick01 March 2021

Muncie Power Products’ new A20 Series PTO is designed for Allison 3000 and 4000 transmissions.

Muncie Power Products, Inc. has announced the release of the new A20 Series power take-off, designed to fit on Allison 3000 and 4000 Series transmissions. The A20 Series PTO incorporates a new rotatable flange with 30 unique, identifiable positions designed to allow great flexibility in finding the optimal position when mounting hydraulic pumps.

Using position codes, customers can choose to order their PTO set to a specific code and have it shipped that way. Alternatively, they 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 easily adjustable without any concern of damaging the shaft seal, Muncie said.

Along with the flange, 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.

Each tool kit contains a torque wrench (optional), tool bag, and all the tools needed to properly 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 duty applications of 415 lb.ft. The PTO is applicable for a number of markets including dump, fire and rescue, refuse, utility, tow and recovery, snow and ice, and bulk hauling.
