Engine preservation

Introduction
The recommendations indicated below are designed to prevent damage to the engine when it is withdrawn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 Use these procedures after the engine is withdrawn from service.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 of fuel, lubricating oil or air. Stop the engine and
drain the lubricating oil from the sump.
4 Renew the canisters) of the lubricating oil filter.
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" on page 23. In order to protect the cooling
system against corrosion, fill it with an approved antifreeze mixture because this gives a protection against
corrosion, see "Coolant specification" on page 43.
Note: If protection against frost is not necessary and a corrosion inhibitor is to be used, it is recommended
that you consult the Service Department, Perkins International Limited, Peterborough.
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 for one to two seconds into each cylinder bore
with the piston at BDC.
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. Then, if necessary, remove the pipes 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.
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.
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 the rocker shaft
assembly. Fit the filler cap or rocker cover.
