8.2 Preservation Transport and storing General Engines contain the following kinds of corrosi- on protection z interior corrosion protection z Exterior corrosion protection tect the different systems. fluid system (cooling water with cooling system protection agent).See the chapter Exterior cor- rosion protection for the cooling air system.In engines of the oil-cooled series the circulating lubricating oil serves simultaneously for coo- ling. The cooling chambers are protected auto- matically against corrosion with the lubricating oil system.If a coolant with corrosion protection properties is poured into liquid-cooled engines, no further action is necessary after draining.
z If not, the coolant must be drained and, to ensure the formation of a covering layer on the inside surfaces of the cooling system, a corrosion protection run performed with a mixture of: 95% treated water 5% corrosion protection agent z The duration of the corrosion protection run and the concentration of the corrosion pro- tection agent are specified by the manufac- turer of the corrosion protection agent. z Then drain the coolant. Fuel system z Fill the fuel tank with a mixture of: 90% distilled fuel 10% corrosion protection oil SAE 20W-20 z Perform a corrosion protection run with no load for at least 5 minutes.
The following corrosion protection work may only be carried out by persons familiar with it and instructed in the potential dangers. Due to the following corrosion protection measures af- ter shutting down the engine the require- ments for 12 month protection are met. If these measures are deviated from by exposing the corrosion-protected engines or parts to unfa- vourable conditions (installation outdoors or storage in damp, badly aired places) or dama- ge to the corrosion protection layer, a shorter corrosion protection duration is to be expected. The engine corrosion protection should che- cked about every 3 months by opening the co- vers.
If corrosion is detected, the corrosion protection should be renewed. At the end of the corrosion protection work the crank drive may no longer be turned so that the corrosion protection agent in the bearings, bearing liners and cylinder liners is not scraped off.Before operating a corrosion protected engine, the corrosion protection must be removed. Lubricating oil system z Drain lubricating oil from warm engine. z Thoroughly clean oil tray, cylinder head with rocker arms, valves, valve springs with die- sel fuel or cleaning agent.
z Fill the engine with corrosion protection oil SAE 20W-20 up to the MAX mark and per- form a corrosion protection run for at least 5 minutes so that all the components of the lu- bricating oil system are wetted or all acces- sible parts are wetted with corrosion protection oil and pump corrosion protection oil through the engine with a separate pump until all bearings and bearing liners are wet- ted. 8 Air intake pipes After the corrosion protection run, remove the cylinder cover and deinstall injectors. The re- spective piston must be set to LDC. z The accessible part of the cylinder liner should be coated with corrosion protection oil with a spray lance through the opening.
z Spray corrosion protection oil SAE 20W-20 into air intake pipe. Oil drips in lines are not permissible and must be sucked off if necessary. Air compressor With a mounted air compressor a corrosion protection agent should be sprayed into the air compressor intake system after switching off the engine until the agent visibly emerges from the adapter. interior corrosion protection Interior corrosion protection is always provided by wetting of the walls with the implemented corrosion protection agent in a corrosion pro- tection running of the engine.
