AUTOMATIC TRANSMISSION AND DIFFERENTIAL
(wlool 3- 2
W SERVICE PROCEDURE
1 . Precaution
When disassembling or assembling the automatic
transmission, observe the following instructions .
1) Workshop
Provide a place that is clean and free from dust . Princi-
pally the conventional workshop is suitable except for a
dusty place. In a workshop where grinding work, etc .
which produces fine particles is done, make indepen-
dent place divided by the vinyl curtain or the equivalent .
2) Worktable
The size of 1 x 1 .5 m (40 x 60 in) is large enough to work,
and it is more desirable that its surface be covered with
flat plate like iron plate which is not rusted too much .
3) Cleaning of exterior
(1) Clean the exterior surface of transmission with
steam and/or kerosene prior to disassembly, how-
ever it should be noted that vinyl tape be placed on
the airbreather or oil level gauge to prevent infiltra-
tion of the steam into the transmission and also the
cleaning job be done away from the place of disas-
sembly and assembly .
(2) Partial cleaning will do, depending on the extent
of disassembly (such as when disassembly is limited
to some certain parts) .
4) Disassembly, assembly and cleaning
(1) Disassemble and assemble the transmission
while inspecting the parts in accordance with the
Troubleshooting .
(2) During job, don't use gloves. Don't clean the parts
with rags : Use chamois or nylon cloth .
(3) Pay special attention to the air to be used for
cleaning . Get the moisture and the dust rid of the air
as much as possible . Be careful not to scratch or dent
any part while checking for proper operation with an
air gun .
(4) Complete the job from cleaning to completion of
assembly as continuously and speedily as possible in
order to avoid occurrence of secondary troubles
caused by dust . When stopping the job unavoidably
cover the parts with clean chamois or nylon cloth to
keep them away from any dust.
(5) Use kerosene, white gasoline or the equivalent as
washing fluid . Use always new fluid for cleaning the
automatic transmission parts and never reuse . The
used fluid is usable in disassemble and assemble
work of engine and manual transmission .
(6) Although the cleaning should be done by dipping
into the washing fluid or blowing of the pressurized
washing fluid, the dipping is more desirable. (Do not
rub with a brush.) Assemble the parts immediately
after the cleaning without exposure to the air for a
while. Besides in case of washing rubber parts, per-
form the job quickly not to dip them into the washing
fluid for long time .
(7) Apply the automatic transmission fluid (ATF) onto
the parts immediately prior to assembly, and the
specified tightening torque should be observed care-
fully.
(8) Use vaseline if it is necessary to hold parts in the
position when assembling .
(9) Drain ATF and differential gear oil into a saucer so
that the conditions of fluid and oil can be inspected .
(10) Do not support axle drive shaft, stator shaft,
input shaft or various pipes when moving transmis-
sion from one place to another.
(11) Always discard old oil seals and bushings, and
install new ones .
(12) Do not reuse old pipes, gaskets, plugs (1/8'),
spring pins, etc. Install new ones .
(13) Be sure to replace parts which are damaged,
worn, scratched, discolored, etc .
