TRANSMISSION LUBRICATION SYSTEM

T h e t a p e r b e a r i n g s o n t h e i n p u t s h a f t g e t
lubrication from oil that is thrown by the direction
clutches.
The taper bearings on the shaft for the idler gear
get lubrication through passage (6). Some of the oil
from the direction clutches goes into hole (5) and
through passage (6) to the taper bearings.
The lubrication oil to the planetary transmission
goes through passage (7) to the outside of the main
transmission shaft and through four drilled holes
(8) to a small passage around the center passage in
the main shaft.
PLANETARY LUBRICATION
The main shaft has a tube installed inside it to
make a center passage. This center passage lets P1
pressure oil go to the No. 7 clutch.
The lubrication oil flows through a small passage
around the center passage in the main shaft. Drilled
holes in the main shaft let lubrication oil (from the
small passage around the center passage) go to the
bearings of the planet gears.
All other gears and clutches get lubrication from
oil thrown by the turning components or from
leakage from the shafts with pressure oil. The
leakage then goes to the transmission reservoir.
