Safety Precautions
CAUTION
Do not operate the engine if the
alternator is producing unusual sounds.
Damage to the alternator will result.
CAUTION
If the engine coolant pump must be
replaced, replace the engine coolant
pump as an assembly only. Do not
attempt to repair the engine coolant
pump or replace individual components.
CAUTION
Use a new special O-ring between the
engine coolant pump and the joint. Be
sure to use the special O-ring for each
engine model. Although the O-ring
dimensions are the same as a
commercially available O-ring, the
material is different.
CAUTION
Remove or install the high-pressure fuel
injection lines as an assembly whenever
possible. Disassembling the
high-pressure fuel injection lines from
the retainers or bending any of the fuel
lines will make it difficult to reinstall the
fuel lines.
CAUTION
After marking the position of the pump
drive gear, do not rotate the engine
crankshaft. Rotating the crankshaft will
cause the fuel injection pump to become
misaligned.
TNV DI Service Manual
Do not use a high-pressure wash
directly on the alternator. Water will
damage the alternator and result in
inadequate charging.
0000039en
Do not reverse the positive (+) and
negative (-) ends of the battery cable.
The alternator diode and stator coil will
be damaged.
0000041en
When the battery indicator goes out, it
should not come on again. The battery
indicator only comes on during
operation if the alternator fails. However,
if an LED is used in the battery indicator,
the LED will shine faintly during normal
operation.
0000042en
Using a non-specified V-belt will cause
inadequate charging and shorten the
belt life. Use the specified belt.
Agricultural or other chemicals,
0000047en
especially those with a high sulfur
content, can adhere to the IC regulator.
This will corrode the conductor and
result in battery over-charging (boiling)
and charging malfunctions. Consult
Yanmar before using the equipment in
such an environment or the warranty is
voided.
