Engine: Cummins 4BT3.9

7.12 ENGINE STORAGE

If the engine is properly protected and stored according

to the following recommendations, no corrosion damage

will normally occur. Cummins Engine Company, Inc. and

OmniQuip International are not responsible for any

damage that occurs in relation to a service storage

period.

Use the following procedures immediately upon removing

engine from service if being stored for an extended period

of time.

1. Clean the outside of the engine.

2. When using a preservative fuel, drain the fuel

system and fill with the preservative fuel. When not

using preservative fuel, keep the fuel system

charged with regular fuel, which, along with the fuel

filter, will have to be drained and discarded at the

end of the storage period.

3. Run the engine to operating temperature. Correct

any fuel, fluid, oil or air leaks. Stop the engine and

drain the oil.

4. Replace the oil filter.

5. Fill the crankcase (sump) to the FULL mark on the

dipstick with new, clean oil or with an approved

preservative fluid. If a preservative fluid is used, it

must be drained and replaced with regular

lubricating oil before the engine is returned to

service.

6. Drain the cooling system. To provide protection

against corrosion, fill the cooling system with a

coolant containing a corrosion inhibitor. If frost

protection is needed, use the appropriate mixture of

anti-freeze and water. If frost protection is not

required, use an appropriate mixture of water with an

approved corrosion mixture.

7. Run the engine for a short period to distribute

lubricating oil and coolant throughout the engine.

8. Clean out the engine breather pipe (where fitted),

and seal the end of the pipe.

9. Remove the fuel injectors and spray clean engine

lubricating oil into cylinder bores. Evenly divide four

ounces (118,3 ml) of lubricating oil between the four

cylinders.

10. Remove the air filter and any pipe installed between

the air filter and the induction manifold. Seal the

manifold with waterproof tape.

11. Remove the exhaust pipe. Seal the manifold with

waterproof tape.

12. Disconnect the battery and store it safely, in a fully

charged condition. Before the battery is put into

storage, give the battery terminals a protection

against corrosion with a light coating of dielectric

grease or petroleum jelly.

13. Seal the vent pipe of the fuel tank or the fuel filler

cap with waterproof tape.

14. Remove and store the fan drive belt.

Note: Before starting the engine after storage, operate

the starter motor with one of the fuel shut-off solenoid

wires disconnected for 15 seconds or until the dash

panel low oil pressure warning indicator goes out. This

will allow oil to be circulated throughout the engine to

prevent damage to internal components.
