9. Inspect the sun gear shaft splines

for burrs and wear.

10.
Check the fit of the seal rings

in the grooves of the shaft. The rings

should enter the grooves freely with-

out bind.

11.

Individual parts of the planet car-

riers are not serviceable.

1.
The pins and shafts in the planet

assemblies should be checked for loose

fit and/or complete disengagement.

Use a new planet assembly if either

condition exists. Before installing a

planet assembly, the shaft retaining

pins should be checked for adequate

staking. If staking does not appear

adequate, the pins should be restaked

before installation. When restaking,

the retaining pins must not be driven

into the carrier any further than 0.040

inch below the surface of the carrier.

Thread Repair-Case

Thread service kits may be pur-

chased from local jobbers or the

Heli-Coil Corporation. To repair a

damaged thread, the following proce-

dures should be carefully followed.

1.
Drill out the damaged threads,

using the same drill size as the thread

01).
For example, use a 5/16-inch

drill for a 5/16-18 thread.

2.
Select the proper special tap and

tap the drilled hole. The tap is marked

for the size of the thread being re-

paired. Thus, the special tap marked

5/16-18 will not cut the same thread

as a standard 5/16-18 tap. It does cut

a thread large enough to accommo-

date the insert, and after the insert is

installed the original thread size

(5/16-18) is restored.

3.
Select the proper coil inserting

tool. These tools are marked with the

thread size being repaired. Place the

insert on the tool and adjust the sleeve

to the length of the insert being used.

Press the insert against the face of

the tapped hole. Turn the tool clock-

wise and wind the insert into the hole

until the insert is 1/2 turn below the

face.

4.
Working through the insert, bend

the insert tang straight up and down

until it breaks off at the notch.

5.
If the inserts are not properly in-

stalled, they can be removed with the

extractor tool. Place the extractor tool

in the insert so that the blade rests

against the top coil 1/4 to 1/2 turn

away from the end of the coil. Tap

the tool sharply with a hammer so

that the blade cuts into the insert.

DESCRIPTION

DESCRIPTION

Figure 1 shows the location of the

converter, front pump, clutches,

bands,
gear train and most of the in-

ternal parts used in the FMX Trans-

mission

The identification tag (Fig. 2) on an

FMX transmission is attached under

the oil pan by a pan to case bolt. The

tag includes the model prefix and suf-
fix, assembly part number and the

build date code.

The service identification number

indicates changes to service details

which affect interchangeability when

the transmission model is not

changed. For interpretation of this

number, see the Master Parts Catal-

og-

The tag must be kept with the indi-

vidual transmission it was originally
installed on. If the tag was removed

during disassembly, reinstall it on the

same unit.

The FMX transmission is a three

speed unit capable of providing auto-

matic upshifts and downshifts through

the three forward gear ratios, and also

capable of providing manual selection

of first and second gears.

The transmission consists essentially

of a torque converter, planetary gear

train, two multiple disc clutches and a

hydraulic control system (Fig. 3).
