HYDRA-MATIC TRANSMISSION
Fig. 6-82 Testing for Torus Cover Leaks
1. Install plug, part of Torus Cover Hub Plug
and Valve Adapter J-7073, into torus cover hub,
with hub flange on inside of torus cover, Fig.
6-82. Tighten securely in place.
CAUTION: Be sure that flange of hub plug
is on inside of torus cover, otherwise plug
might be forced out of cover when air pressure
is applied.
2. Attach flywheel to torus cover, using a new
flywheel-to-torus cover seal and eight nuts. It
is not necessary to install the four nuts that
secure engine drive plate to flywheel.
3. Remove oil drain plug from cover and install
Valve Adapter, part of J-7073, in drain hole.
4. Apply compressed air with a service air
hose until approximately 50 psi air pressure is
obtained.
5. Immerse assembly in a liquid, noting any
sign of bubbles that would indicate a leak.
If a flywheel assembly is not available, an
alternate method using a soap solution may be
used. Using a paint brush, apply solution to all
areas where leaks may occur and check for signs
of bubbles.
6. Depress valve stem in Adapter to release
air pressure, then remove Adapter.
CAUTION: Always release air pressure be-
fore removing Valve Adapter, as a definite
hazard exists should Adapter blow out during
removal.
7. Remove eight nuts holding flywheel to torus
cover and remove flywheel.
NOTE: Make sure parts are thoroughly dry
before assembly into transmission.
20. Bushing Replacement Procedures
The special tools referred to in the following
procedures are part of Bushing Service Tool Set,
J-8532.
a. General Instructions
Before installing any precision bushing, be sure
that bore into which it is to be driven is clean and
free of burrs. Remove burrs with a scraper or
small file. Protruding metal in these bores can
distort the precision bushing, making it tight on
shaft.
When staking extension housing bushing, be sure
to force staking tips as far into metal as possible.
They should always be located in the oil groove.
Also check to see that a burr is not raised above
bearing surface after staking. Any such burrs
must be removed carefully with a bearing scraper.
Be extremely careful with reamers and reamer
guide fixtures to avoid damaging locating or cut-
ting edges. These are precision tools and one
nick can render them useless.
Always store tools in their proper compartment
in tool box. This will make it easy to choose the
correct driver for each bushing. Using a driver
which is "almost" correct may damage the bush-
ing during installation.
b. Flywheel-Figs. 6-83, 6-84
1. Place flywheel on bench with bushing side up.
2. Locate split in bushing and start point of
Chisel, J-8400-1, beside split with flat side of
Chisel facing in, Fig. 6-83.
8. Remove Hub Plug.
