Exterior corrosion protection
The engine must be cleaned thoroughly with a
cleaning agent before exterior corrosion pro-
tection. Any signs of corrosion and damage to
the paintwork must be removed.
Cooling air system in air-cooled engines
The air duct space in V engines is unpainted
and must be sprayed with a corrosion protec-
tion agent.
Bare exterior surfaces and parts
Coat or spray all bare exterior parts and sur-
faces (e.g. flywheel, flange faces) with corrosi-
on protection agent.
Rubber parts
Rubber parts (e.g. muffs) which are not painted
over must be rubbed down with talcum pow-
der.
Belt drives
Remove V-belts and V-rib belts and store pa-
cked. Spray V-belt pulleys and tension pulleys
with corrosion protection agent. Toothed belts
to the engine control may not be removed.
Engine openings
All engine openings must be fitted with air-
tight, water-tight covers to delay the liqueficati-
on process of the corrosion protection agents.
With installed air compressor, the suction and
pressure connection must be sealed by a cap.
Air should be locked out to avoid ventilation of
the engine (chimney effect) for the suction from
an air supply pipe.
Storage and packaging
After being protected against corrosion, the en-
gine must be stored in a dry, ventilated hall and
suitably covered. The cover must be placed
loosely over the engine so that the air can cir-
culate around it to prevent condensation from
forming. Use a dessicant if necessary.
Removal of corrosion protection
The corrosion protection must be removed
from the corrosion protected engine before
starting. The packaging must be removed as
well as all covers from the sealed openings.
Any signs of corrosion and damage to paint-
work must be removed.
Fuel system
z
If there is a mixture of diesel fuel/corrosion
protection oil in the fuel tank, drain it.
z
Fill the fuel tank and fuel system with the
proper fuel.
Coolant system
z
If the implemented corrosion protection
agent is compatible with the intended
coolant system protection agent, this can be
filled directly into the coolant system as spe-
cified.
z
If it is uncertain whether the implemented
corrosion protection agent is compatible
with the coolant system protection agent,
the cooling system should be purged with
fresh water for about 15 minutes before fil-
ling.
Removal of exterior corrosion protection
z
Wash all surfaces and components coated
with corrosion protection agent with distilled
fuel or a suitable cleaning agent.
z
Wash out grooves of V-belts if necessary.
z
Mount V-belts or V-rib belts as specified.
