Transmission clutch (6—Fig,
AC83),
engine clutch shaft (2), power
take-off drive (5) and intermediate
gear (12) are contained in the torque
tube.
However, this tractor model can
be equipped in one of three ways:
(a) with gear and flange for driving
power take-off unit and for connecting
transmission clutch as shown; (b) with
flange only for connecting transmis-
sion clutch; (c) with splined coupling
sleeve where neither power take-off
unit nor transmission clutch is used.
BASIC PROCEDURE. Although
most repair jobs will involve overhaul
of the complete unit, there are infre-
quent instances where the failed or
worn part is so located that the repair
work can be completed safely without
complete disassembly of the torque
tube.
In effecting such localized re-
pairs,
considerable time will be saved
by observing the following as a gen-
eral guide.
Clutch Shaft. Removal of engine
clutch shaft (2) requires detaching
clutch housing from torque tube and
torque tube from transmission.
Transmission Clutch, Removal of

C—Tractors within the serial range of 71146 to 72138 and all tractors after 7S645 are
equipped with the new torque tube and clutch shaft, which is fitted with two 222540
oil seals as shown. Tractors within the serial ranges of 70966 to 71146, and 72138 to
75645, although equipped with the new torque tube and clufcfi shaft, are factory
equipped with only one oil seal. When servicing all models which have the new torque

two 222540 oil seals should be installed as shown (lips opposite to each other)
on all tractors after 70966 or all tractors equipped with the new torque tube and clutch
