4. Drain the lube oil from the oil pan.
5. Loosen the belt tension on fan belt,
alternator belt, water pump belt and
other accessories driven by belt.
6. Put a tag to the engine which must
indicate:
• Engine preservation process date.
• Engine is treated for preservation
for a period of 6 months. Due date
for the next preservation process
(if not installed to the equipment).
STORAGE OF THE ENGINE THAT IS
INSTALLED ON THE EQUIPMENT
Many times, engines shipped from the
factory are installed on the equipment
within six months from the date of
shipment from the factory. But these
engines as installed in the equipment are
not put in service for a long period. For
such engines the engine coolant and engine
lube oil is generally filled in the engine and
no special process is required, but periodic
running is a mandatory requirement.
• Run the engine once in every week for 5
to 10 minutes at low idle rpm. “B”
check to be carried out at every six
months as mentioned in Operation &
Maintenance manual 3243773
(Cummins Part number).
PREPARE THE STORED ENGINE
FOR PUTTING IN SERVICE
1. Clean off the accumulated dirt from
exterior of the engine.
2. Remove all protected caps, wrappings
and tape from connections such as
breathers, fuel-in and out connections,
water-in and out connections etc.
3. Use the suitable solvent, cleaner or
degreaser to remove rust preventive
compound from unpainted external
surfaces of the engine.
4. Fill the oil pan with the new lube oil.
Replace the fuel, lube oil filters and lube
oil bypass filters only when the engine
is stored beyond six months from the
date of shipment.
5. Check and correct the engine belt
tensioning.
6. In case of any doubts, contact Atlas
Copco or Cummins dealer for more
info.
The above procedure is to be
done repeatedly at the end of
every six months during the
storage period and must be done
at OEM works on the equipment
/ on the engine testbed depending
upon the location of the engine.
Engine must be sent to Cummins
HHP rebuild plant for
revalidation after 3
preservations at site (before
completion of 24 months at
OEM).
If case any one of the three
preservation is missed, then the
concerned Cummins Area
Service Manager (ASM) should
certify the condition of the engine
coolant, lube oil, fuel and exhaust
systems. In case of abnormality,
the engine is to be sent to HHP
rebuild plant for revalidation.
