2.2 ENGINE STORAGE
2.2.1 Storage less than 1 year
Storing engines requires special attention. Clarke
engines, as prepared for shipment, may be stored for
a minimum of one year. During this period, they
should be stored indoors in a dry environment.
Protective coverings are recommended provided they
are arranged to allow for air circulation. The stored
engine should be inspected periodically for obvious
conditions such as standing water, part theft, excess
dirt buildup or any other condition that may be
detrimental to the engine or components.
Any such conditions found must be corrected
immediately.
2.2.2 Extended Storage Maintenance Procedure
After a one year storage period or if the engine is
being taken out of service for more than 6 months,
additional preservation service must be performed as
follows:
1) Drain the engine oil and change the oil filter.
2) Refill the engine crankcase with MIL-L-
21260 preservative oil.
3) Change the fuel filters.
4) Install the coolant plugs and install coolant in
the normal mix percentage of 50% coolant,
50% water, premixed.
5) Remove the protection from the intake and
exhaust openings.
6) Prepare a preservative fuel container as a fuel
source using a fuel conditioner mixture of
C02686 or C02687 with ONLY Diesel #2
fuel or “Red” diesel fuel (ASTM D-975) or
BS2869 Class A2. (Refer to Section 3.1.1 for
Fuel Specification.)
7) Disconnect the coupling or drive shaft from
the pump.
8) Start and run the engine at a slow speed for
1-2 minutes being careful not to exceed the
normal operating temperature.
9) Drain the oil and coolant.
10) Replace the protective plugs that were used
for shipping and storage.
11) Attach to the engine a visible card, specifying
“ENGINE WITHOUT OIL” DO NOT
OPERATE”.
IMPORTANT: THIS TREATMENT MUST BE
REPEATED EVERY 6 MONTHS
************************
PUTTING ENGINE INTO SERVICE AFTER
ADDITIONAL PRESERVATION SERVICE:
To restore the normal operation running conditions of
the engine, carry out the following:
1) Fill the engine sump with the normal
recommended oil, to the required level.
2) Remove the protective plugs used for
shipping and storage.
3) Refill cooling water to proper level.
4) Remove the card “ENGINE WITHOUT OIL,
DO NOT OPERATE”.
5) Follow all steps of the Installation
Instructions when the engine will be put into
service.
2.3 INSTALLATION INSTRUCTIONS
The correct installation of the engine is very
important to achieving optimum performance and
extended engine life.
