Jim Abbott – Product Planning and Application Engineer

The P58 Series power take-off (PTO)—which is manufactured by our sister company, Interpump Hydraulics—is available for the PACCAR TX-8 transmission.

The PACCAR TX-8 is a medium-duty, automatic transmission available only in PACCAR trucks. The PTO opening is a proprietary 8-bolt pad, located on both sides of the transmission. The transmission is manufactured by ZF, and will have a ZF tag on the transmission with POWERLINE listed as the model.

Trucks must be ordered with the correct PTO prep codes in order to have correct PTO capability.
