CHANGING

THE

TRANSMISSION

FLUID

After

the

initial

50

hour change, the transmission

fluid

should

be

changed at

every

300

operating hours thereafter or at

winter

haul-out

However,

the fluid must be changed when-

ever

it

becomes

contaminated, changes color, or smells rancid.

0

Remove

the

fluid

filler cap

and

dipstick.

0

Remove

the

fluid

cooler return line and allow the fluid

to

drain

into a

container.

0 Reconnect

the

fluid

cooler return line.

0

Use

a suction

pump

to

remove the transmission fluid

through

the

filler

cap/dipstick hole.

0 Clean off the transmission and properly dispose

of

the

used

fluid.

Refill

the

transmission with

DEXTRON

III

ATF.

The

quantity will vary depending on the transmission

model

and

the installation

angle.·

Fill through the-dipstick hole.

0 Check the dipstick for the proper fluid

level.

0 Replace the fluid filler cap and dipstick. (Press the

llipstick into place and tum clockwise until

finger-tight.)

D. Run the engine, shutdown and recheck the

fluid

level.

A

WARNING:

Never

pull

out

the

dipstick

while

the

engine

Is

running.

Hot

fluid will

splash

from

the

dipstick

hole.

This

could

cause

severe

bums.

Fluid

Capacity

ApProximately 2.5 quarts (2.36liters) will

fill

most

transmissions

to

the fluid level

fill

mark on

the

dipstick.

Many variables have a direct relationship

to

the

fluid

capacity.

Additional fluid will be required

to

fill

the

fluid

cooler and the cooler lines. The angle of installation

will

make

a difference in the quantity of fluid

required

to

fill

the

transmission.

,

PRESSURE

GAUGE

An optional mechanical pressure gauge can

be

installed at

the

control panel to constantly monitor the pressure

of

the

transmission

fluid.

A normal reading at 2000 rpm in

MAINTENANCE

Transmission maintenance is minimal.

Keep

the exterior

housing clean, check the fluid level

as

part

of

your regular

routine, and change the fluid

every

300 operating

hours.

Periodically inspect the transmission and the cooler

for

leaks

and corrosion. Make certain the

air vent is clear and

when

checking

theJI.uid

level look for signs

of

water contamination

·(fluid will appear

as

strawberry cream).
