CHECKS AND ADJUSTMENTS (Cont'd)
Governor Oil Level
See the
SERVICE
SCHEDULE
Section 1 for the service
interval for checking the governor oil level. Use the
following procedure:
Remove the check plug
(Item 1) [A).
If oil flows out the hole, the level is adequate.
If
no oil flows out the hole, remove the fill plug (Item 2)
[A]
at the top of the governor and add SAE
10W-30
or
10W-40
until oil flows from the check plug hole. Install the
plug and tighten.
Grease the fittings at the shaft every
200-500
hours with
a multi-purpose grease.
Ignition System
Coil to Ground Voltmeter Test
Connect the voltmeter wires as shown in [B).
Operate the starter until the breaker points are fully
closed.
Turn
all the lights and accessories off.
Turn the ignition switch on.
If the voltmeter reading is 0.25 volt
or
less the primary
circuit from the oil to the ground is good.
If
the voltmeter reading is more than 0.25 volt test the
voltage loss between each of the
following:
The connector marked DIST on the coil and the
connection on the distributor.
The moving breaker point and the stationary breaker
point.
The breaker point the distributor.
The distributor housing the engine ground.
If the voltage loss of all the above has a total of more than
0.25 volts, it will cause bad engine perfonnance.
Spark Plug Wires Resistance Test
These wires include the wires connecting the distributor
cap to the spark plug and the wire connecting the center
connection of the distributor cap to the center connection
of the ignition
coil.
these wires are the radio resistance-type. The resistance
of each wire must not be more than 5000 ohms per inch.
When checking the resistance of the wires
or
adjusting
ignition timing, do not damage the wires. This can cause
separation in the conductor.
Spark Plug Test
Check and clean the electrodes and adjust the spark plug
gap. After the gap is correct, check the plugs on a testing
machine. Compare the operation of the old plug with a
new plug.
