GENERAL DESCRIPTION

00-2 POWER TAKE OFF GENERAL DESCRIPTION The side with an oil pump PTO integrates the PTO and the oil pump and installed in the left side of a transmission. The shift rod for switching the “ON” and “OFF” of the hydraulic circuit of the PTO is provided at the bottom of the PTO and the oil pump main unit. The “ON” and “OFF” of the PTO uses a gear slide system and turn on and off the power by sliding the output gear. The idle gear bearing uses a needle bearing and the output shaft uses a ball bearing to ensure durability.

The oil pump section consists of the gear pump part and the hydraulic circuit switching part, and the gear pump sec- tion fixs efficiency by selecting and assembling the side plate. Further, the hydraulic circuit switching portion switches the three positions of “Up”, “Neutral”, and “Down” by the spool provided on the rod extension. The dump control system uses a cable system.
