OPM-134/B
element, from the inside outward (maximum pressure
200 kPa). Do not use detergents; do not use diesel.
4. Replace the filter if any breakages or tears are found.
5. Reassemble by repeating the above operations in
reverse
order
6. Reinstall the element into the air cleaner case.
ADJUSTING THE GOVERNOR
Never attempt to adjust the low or high idle speed limit
screw. This may impair the safety and performance of the
machine and shorten its life. If adjustment is ever required,
contact an authorized service center.
1. Check that the governor lever (1) makes firm contact
with the high idle stop (2) and the low idle speed limit
screw (3) when the engine speed control is in the full
speed or low idle speed positions.
2. If the governor lever does not make proper contact
with the high idle stop or the low idle speed limit
screw, adjust the throttle cable or linkage as necessary.
WARNING: EQUIPMENT DAMAGE
Do not force the throttle cable or linkage to move.
This may damage the governor lever, the throttle
cable or linkage and cause irregular operation of the
engine speed control.
STORAGE
PREPARING THE ENGINE FOR A LONG PERIOD
OF INACTIVITY
In the case of a planned period of inactivity that lasts
longer than one month, to prevent the interior parts of the
engine and some components of the injection system from
oxidizing, prepare the engine as follows:
One Month
1. While the engine is running, treat upper cylinders by
spraying engine fogging agent into the air intake
for about two minutes. Open throttle for short bursts of
speed, shut off engine and allow it to come to a stop
while continuing to spray into air intake.
2. If engine is less transmission, spray flywheel and ring
gear with mixture of one part recommended engine
oil, and one part Stoddard Solvent or equivalent.
3. Check coolant protection. Store indoors in dry area.
Infinite period
In order to prevent oxidation of the internal parts of the
engine and of certain components in the injection system,
when the engine is expected to be inoperative for periods
of more than two months, the following operations must
be carried out in preparation for this:
1. Drain the lubricant from the sump, after first warming
up the engine.
2. Fill the engine with protective oil type 30/M (or
alternatively oil that complies with MIL 2160B type 2
specifications), up to the “minimum” level indicated on
the dipstick. Start the engine and keep it running for
approximately 5 minutes.
3. Drain the fuel from the injection circuit, from the filter
and from the injection pump pipes.
4. Connect the fuel circuit to a tank containing CFB (ISO
4113) protective fluid, and feed in the fluid by putting
the circuit under pressure and running the engine for
approximately 2 minutes, after first disabling the
injection system. This operation can be performed by
polarizing terminal 50 of the starter motor with a
positive voltage equivalent to the rated voltage of the
system, using a conductor provided for that purpose.
5. Nebulise approximately -- g of 30/M protective oil (10 g
per liter displacement) into the turbocharger suction
inlet, during the pressurized filling operation described
in the previous point.
6. Close all the suction, delivery, ventilation and bleeder
openings in the engine with suitable plugs, or seal
them with adhesive tape.
7. Drain the residual 30/M protective oil from the sump.
This oil can be used again for a further 2 preparation
operations.
8. Attach signs reading “ENGINE WITHOUT OIL” to the
engine and to the on-board control panel.
9. Drain the coolant, if it has not been mixed with suitable
antifreeze and corrosion inhibitors, and affix a sign to
indicate the fact. In the event of prolonged inactivity,
the operations described must be repeated every 6
months, following the procedure given below:
A) drain the 30/M protective oil from the sump;
B) repeat the operations described from point 2 to
point 7.
Should you intend to protect external parts of the engine,
proceed by spraying OVER 19 AR protective liquid on
unpainted metal parts, such as the flywheel, pulleys and
the like, avoiding belts, connector cables and electrical
equipment.
