POWER TAKE-OFF (PTO)
Peterbilt Motors Company 8-8
REAR ENGINE PTO
Rear Engine PTO (REPTO) is commonly used in cement mixer and feed lot applications. The REPTO is driven off the
rear gear train on the engine. There is a 1350/1410 flange on the bell housing in the 1 o’clock position that can be used to
attach a hydraulic pump or driveshaft. See Figure 8.15 for an example. The REPTO flange will always be turning when
the engine is running and the output rotation is the same as the engine. The Cummins ISL9 and PX-9 REPTO turns at a
rate of 1.15:1. The Cummins ISX-12 REPTO turns at a rate of 1.32:1. The Paccar MX REPTO turns at a rate of 1.2:1.
