Select your flange position:

The A20 and A30 features a rotatable flange with 30 unique positions. Select the PTO opening you intend to use below to review the 30 position codes.

Once you have found the ideal flange position, you can add the position code characters to the end of the A20 or A30 part number (shown in red below) to have the flange shipped with the preferred arrangement. Alternatively, you can easily set this arrangement before, during, or after installing the PTO.

Pre-set position may not be available through all distribution partners.

The torque rating of this PTO is based on the Allison drive gear rating (for single PTO) of 685 lb.ft. continuous rating and is shown on this page. The CS41 and CD40 PTO ratings are found on page 22 with continuous ratings for Fire pump applications to be calculated as shown on page 3. Ratings above the transmission rating are not approved. Refer to the Allison Tech Data Book for more information. The Transmission rating means that PTO CS41-A1007 is rated to 479 lb.ft. intermittent and 429 lb.ft. continuous when used on this series transmission. The CS41-A1010 is rated 332 lb.ft intermittent and continuous. (for 2 PTOs the total torqe rating is 1175 lb.ft. at the transmission gear.)

AVAILABLE WITH THE MUNCIE START®

The Muncie Start is an electronically controlled, modulated clutch engagement system from Muncie Power Products that eliminates torque spikes through the power take-off, truck drivetrain and mounted auxiliary equipment upon startup for high-inertia loads. Allowing for a smooth engagement of the power take-off, Muncie Start increases the life of the PTO and driven mechanical components

AVAILABLE WITH THE EX DRIVE SHAFT EXTENSION

The Muncie EX Drive was designed to fit on Allison 3000 and 4000 series transmissions with retarder or cooler, and allows for large gear or piston pumps to be direct mounted, eliminating the need for timely driveline installations. The EX Drive provides maximum torque from the PTO, and is available for the A20 Series PTO.
