PLANETARY LUBRICATION
l. Oil supply paaaage. 2. Oil supply passage.
All planet gears and bearings are pressure lubri-
cated. After the oil has been cooled by the oil cooler,
it will enter through oil passages (1) and (2) and an
orifice in the transmission end plate.
Oil for lubrication of the No. 1 clutch comes
through an orifice in the transmission end plate.
Oil supply passage (1) is for lubrication of clutches
No. 2, No. 3, No. 4 and rotating clutch No. 5.
Oil for the No. 6 clutch is supplied through oil
supply passage (2).
All clutch leakage oil and return oil goes to the
bottom of the transmission case. This oil then goes to
the main oil reservoir in the output transfer gear
case.
The restrictions to the flow of oil inside the plane-
tary, keep the lubrication pressure at 140 kPa (20
psi).
