Transport and storage Engine corrosion protection protection agent). z Cooling air system, see the Exterior corrosion protection section. z In engines of the oil-cooled series the circulating lubricating oil serves simultaneously for cooling. The cooling chambers are protected automati- cally against corrosion with the lube oil system. z If a coolant with corrosion protection properties is poured into liquid-cooled engines, no further ac- tion 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 pro- tection 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 protection agent are specified by the manufacturer of the corrosion protection agent. z Then drain the coolant. z After the corrosion protection run, remove the cylinder head cover and deinstall injectors. The respective piston must be set to LT. 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 lubricating oil into the suction intake pipe. z The engine must be cleaned thoroughly with a cleaning agent before exterior corrosion protec- tion.
Any signs of corrosion and damage to the 70 © 2009 Exterior corrosion protection Air intake pipes by wetting of the walls with the implemented cor- rosion protection agent in a corrosion protection run of the engine. z The corrosion protection run can be performed once to protect the different systems: z Drain lubricating oil from warm engine. z Thoroughly clean lube oil tray, cylinder head with rocker arms, valves, valve springs with diesel fuel or cleaning agent.
z Fill the engine with corrosion protection oil up to the MAX mark and perform a corrosion protec- tion run for at least 5 minutes so that all the com- ponents of the lubricating oil system are wetted or wet all accessible parts with corrosion protec- tion oil and pump corrosion protection oil through the engine with a separate pump until all bear- ings and bearing liners are wetted. Close the fuel/tank/supply line to the en- gine so that the system is protected against dirt and dust. Protect the electronics against moisture and corrosion. z Fill the fuel tank with a mixture of: 90 % distilled fuel 10 % corrosion protection oil.
z Perform a corrosion protection run with no load for at least 5 minutes. z Depending on the series the engines are equipped with cooling air, cooling oil or cooling fluid system (cooling water with cooling system Lubricating oil system Fuel system Cooling system Engines contain the following types of corrosion pro- tection: The following measures for corrosion protection af- ter taking the engine out of operation meet the re- quirements for 12 months corrosion protection. The following corrosion protection work may only be carried out by persons familiar with it and instructed in the potential dangers.
If these measures are deviated from by exposing the corrosion-protected engines or parts to unfavourable conditions (installation outdoors or storage in damp, badly aired places) or damage to the corrosion pro- tection layer, a shorter corrosion protection duration is to be expected. The engine corrosion protection should be checked about every 3 months by opening the covers. If cor- rosion 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. z Interior corrosion protection is always provided Your DEUTZ partner has the right corro- sion protection agent for your needs. z Interior corrosion protection z Exterior corrosion protection Interior corrosion protection 8 General Your DEUTZ partner has the right corro- sion protection agent for your needs.
