Turn the flywheel counterclockwise in order to

put the dial indicator at position (D). Write the

measurement in the chart.

Add the lines together in each column.

Subtract the smaller number from the larger

number in column B and column D. Place this

number on line III. The result is the horizontal

eccentricity (out of round). Line III in column C is

the vertical eccentricity.

Damage to the vibration damper or failure of the

vibration damper will increase vibrations. This will

result in damage to the crankshaft.

Replace the damper if any of the following conditions

exist:

from the damper.

excessive heat.

• The damper is bent.

10. Find the intersection of the eccentricity lines

(vertical and horizontal) in Illustration 49.

11. If the point of the intersection is in the “Acceptable”

range, the bore is in alignment. If the point of

intersection is in the “Not acceptable” range, the

flywheel hous ing must be c hanged.

•

•

The bolt holes are worn or there is a loose fit for

the bolts.

The engine has had a crankshaft failure due to

torsional forces.

NOTICE

Inspect the viscous vibration damper for signs of leak-

ing and for signs of damage to the case. Either of

these conditions can cause the weight to contact the

case. This contact can affec t damper operation.

When it is possible, make a test of the charging

unit and voltage regulator on the engine, and use

wiring and components that are a permanent part of

the system. Off-engine testing or bench testing will

give a test of the charging unit and voltage regulator

operation. This testing will give an indication of

needed repair. After repairs are made, perform a test

in order to prove that the units have been repaired to

the original c ondition of operation.

Most of the tests of the electric al system can be done

on the engine. The wiring insulation must be in good

condition. The wire and cable connections must be

clean, and both components must be tight.

Tools

For

The

Charging

System

Never disconnect any charging unit circuit or bat-

tery circuit cable from the battery when the charg-

ing unit is operated. A spark can cause an explo-

sion from the flammable vapor mixture of hydro-

gen and oxygen that is released from the elec-

trolyte through the battery outlets. Injury to per-

sonnel can be the result.

The battery circuit is an electrical load on the charging

unit. The load is variable because of the condition of

the charge in the battery.

NOTICE

The charging unit will be damaged if the connections

between the battery and the charging unit are broken

while the battery is being charged. Damage occurs

because the load from the battery is lost and because

there is an increase in charging voltage. High voltage

will damage the charging unit, the regulator, and other

electrical components.

See Special Ins truction, SEHS7633, “Battery Test

Procedure” for the correct procedures to use to

test the battery. This publication also contains the

specifications to use when you test the battery.

i02554905

Charging System - Test

The condition of charge in the battery at each

regular inspection will show if the charging system is

operating correctly. An adjustment is necessary when

the battery is constantly in a low condition of charge

or a large amount of water is needed. A large amount

of water would be more than one ounce of water per

a cell per a week or per every 100 service hours.

The ammeter is a self-contained instrument that

measures electric al currents without breaking

the circuit and without disturbing the conductor’s

insulation.

The ammeter contains a digital display that is used

to monitor current directly within a range between 1

ampere and 1200 amperes. The multimeter should

be used under only one condition:

• the readings are less than 1 ampere.

A lever opens the ammeter’s jaws over a conductor.

The conductor’s diameter can not be larger than

19 mm (0.75 inch).

The spring loaded jaws clos e around the conductor

for measuring the current. A trigger switch controls

the ammeter. The trigger s witch can be locked into

the ON position or into the OFF position.

After the trigger has been working and the trigger is

turned to the OFF position, the reading appears in

the digital display for five seconds. This accurately

measures currents in areas with a limited access.

For example, these areas include areas that are

beyond the operator’s sight. For DC operation, an

ammeter contains a zero control, and batteries inside

the handle supply the power.

System - Test

Most of the tests of the elec trical system can be

done on the engine. The wiring insulation must be

in good c ondition. The wire and cable connections

must be clean, and both components must be tight.

The battery must be fully charged. If the on-engine

test shows a defect in a component, remove the

component for more testing.

The starting system consists of the following four

components:

• Keyswitch

• Start relay

• Starting motor solenoid

• Starting motor

Trouble with the starting system could be caused

by the battery or by charging system problems. If

the battery is suspect, refer to Troubleshooting,

“Battery”. If the starting system is suspect, refer to

Troubleshooting, “Engine Will Not Crank”.
