The new UD PK9 and PK10 both offer a choice of two manual transmissions, a new larger UD six-speed or a new higher capacity Eaton sourced nine-speed.
The UD MPS63B six-speed transmission offers synchro on second through sixth gear. A Power Take Off (PTO) opening is located on the left hand side of the tramsmission and is rated at 300Nm @ 1.1 nominal ratio.
The power shift mechanism on the new PK (six-speed only) dramatically reduces shift effort for the driver, further combating fatigue. On average shift effort has been reduced by around 50 percent.
The Eaton FS-6109A is a nine-speed full synchro transmission with a mechanical remote control shift with left hand side front, bottom and rear counter shaft transmission PTO openings.
