Preservative oil
Suitable preservative oil can be supplied by most oil companies.
E.g. Dinitrol 40 or equivalent.
Preparations for storage
- Drain and flush the cooling system. Fill with preservative coolant.
- Run the engine until warm with ordinary fuel. Stop the engine and drain
the oil.
- Change fuel filter and turbo filter.
- Fill the engine with preservative oil to the minimum level on the dip-
stick.
- Mix the preservative fuel in a can. Detach the fuel pipe at the feed pump
suction line and connect a hose from the can.
- Detach the fuel pipe at the overflow valve and connect a return hose to
the can.
- Start the engine and run it at about 1,000 rpm (does not apply to single-
speed engines) for 20 - 25 minutes.
- Stop the engine, remove the hoses and connect the normal fuel lines.
- Oil the valve mechanism with plenty of preservative oil.
- Remove the injectors and spray preservative oil into each cylinder
max. 30 cm
3
(ml).
Crank the engine several revolutions using the starter motor.
Spray a little more into each cylinder.
The engine must not then be cranked. Refit the injectors.
- Drain the preservative oil from the engine. New engine oil can be filled
directly or when taking out of storage.
- Drain the coolant if the engine is not to be stored with a full cooling sys-
tem. Plug and tape over all coolant connections (if the cooling system is
not completely assembled).
- Air cleaner: Clean and change the filter insert.
- Cover air intakes and exhaust pipes.
- Alternator and starter motor:
- Spray with water-repellent anti-corrosive oil, CRC 226, LPS1 or equiva-
lent.
- Spray the outside of shiny engine parts, first using penetrating preserva-
tive oil such as Dinitrol 25B and then using Dinitrol 112 or equivalent.
