3.152 Series » Engine preservation

The recommendations indicated below are designed to prevent damage to the engine when it is withdrawn from service for a prolonged period. Use these procedures after the engine is withdrawn from service. The instructions for the use of POWERPART products are given on the outside of each container.

Procedure

1. Completely clean the outside of the engine.
2. When a preservative fuel is to be used, drain the fuel System and fill it with the preservative fuel. POWERPART Lay-Up 1 can be added to the normal fuel to change it to a preservative fuel. If preservative fuel is not used, the system can be kept full with normal fuel but the fuel must be drained and discarded at the end of the storage period together with the fuel filter element(s).
3. Operate the engine until it is warm. Then correct leakages ci fuel, lubricating oil or air. Stop the engine and drain the lubricating oil from the sump.
4. Renew the canister(s) of the lubricating oil fitter.
5. Fill the sump to the full mark on the dipstick with new and clean lubricating oil and add POWERPART Lay-Up 2 to the oil to protect the engine against corrosion. If POWERPART Lay-Up 2 is not available, use a correct preservative fluid instead of the lubricating oil. If a preservative fluid is used, this must be drained and the lubricating oil sump must be filled to the correct level with normal lubricating oil at the end of the storage period.
6. Drain the cooling system: see “How to drain the cooling system???. In order to protect the cooling system against corrosion, ftli il with an approved antifreeze mixture because this gives protection against corrosion. If an approved antifreeze mixture is noî available, add a correct mixture of corrosion inhibitor to the water.
Caution: Certain corrosion inhibitor mixtures could cause damage to some engine components. It is recommended that you consult the Service Department, Perkins international Limited, Peterborough if a corrosion inhibitor is to be used.
7. Operate the engine for a short period in order to circulate the lubricating oil and the coolant in the engine.
8. Disconnect the battery. Then put the battery into safe storage in a fully charged condition. Before the battery is put into storage, protect its terminals against corrosion- POWERPART Lay-Up 3 can be used on the terminals.
9. Clean the engine breather pipe (if one is fitted) and seal the end of the pipe.
10. Remove the atomisers and spray POWERPART Lay-Up 2 into each cylinder bore. If this is not available, clean engine lubricating oil will give a degree of protection. Spray into the cylinder bores 140 rnl (0.25 pint) of lubricating oil divided evenly between the three cylinders.
11. Slowly turn the crankshaft one revolution and then fit the atomisers with new seat washers and new dust seals.
12. Remove the air filter/cleaner. Then, if necessary, remove the pipe(s) installed between the air filter/cleaner and induction manifold or turbocharger. Spray POWERPART Lay-Up 2 into the induction manifold or turbocharger. It is recommended that the spray time for the turbocharger is 50% longer than the spray time for the manifold, which is indicated on the container label. Seal the manifold or the turbocharger with waterproof tape.
13. Remove the exhaust pipe. Spray POWERPART Lay-Up 2 into the exhaust manifold or the turbocharger. Il is recommended that the spray time for the turbocharger is 50% longer than the spray time for the manifold, which is indicated on the container label. Seal the manifold or the turbocharger with waterproof tape.
14. If the lubricating oil filler is fitted onto the rocker cover, remove the filler cap. If the lubricating oil filler is not fitted onto the rocker cover, remove the rocker cover. Spray POWERPART Lay-Up 2 around Ihe rocker shaft assembly. Fit the filler cap or rocker cover.
15. Seal the vent pipe of the fuel tank or the fuel filler cap with waterproof tape.
16. Remove the drive belts and put them into storage.
17. In order to prevent corrosion, spray the engine with POWERPART Lay-Up 3. Do not spray the area inside the alternator cooling fan.

Caution: After a period in storage, but before the engine is started, operate the starter motor with the engine stop control in the "stop" position until oil pressure is indicated. Oil pressure can be indicated either by a gauge or when a low pressure warning light is extinguished. If a solenoid stop control is used on the fuel injection pump, it must be disconnected for this operation.

If the engine protection is done correctly according to the above recommendations. no corrosion damage wil1 normally occur. Perkins is not responsible for damage which may occur when an engine is in storage after a period in service.
