7.After bleeding the air, tighten air bleed plug, then push in the knob of feed pump and lock it in position.

8.Replace Corrosion resistor cartridge (if equipped)

9.Screw in valves at the top of the corrosion resistor.

10.Using a filter wrench, turn the cartridge to the left to remove it.

11.Coat the seal surface of the new cartridge with engine oil and install it to the filter holder.

12.Tighten until he packing surface contacts the seal surface of the filter holder, then tighten a further 2/3 of a turn.

13.Open valves.

Cleaning breather element

1.Loosen the clamp, then remove the hose and take out breather. Wipe off the dirt around the breather. Check the O-ring, and replace if necessary.

2.Wash the breather in diesel fuel or flushing oil, blow dry with compressed air, then reinstall it.

3.Inspect the hose and if there is any deteriorated oil stuck inside the hose. Replace hose if necessary.

Greasing

Using a grease pump, grease the fan hub (1 place) and tension pulley (2 places).

DCA-400SSK — MAINTENANCE

Generator Storage

For storage of the generator for over 30 days, the following is required:

zFill the fuel tank completely, lubricate and change oil.

zDisconnect the negative terminals of the battery and cover it, or remove it from the machine and store it separately.

zIf the ambient temperature is expected to drop below 0oC, add antifreeze to the radiator.

Removal from long term storage:

zApply oil to the engine valve and rocker arms, and examine the operating condition of the valves.

zRemove the oil filler pipe from the turbocharger oil inlet port, add 0.5-1L (0.13-0.26gal) of oil to the turbocharger, reinstall the oil filler pipe.

zChange the oil in engine oil pan.

zReplace all the filters.

zFlush the inside of the cooling system.

zDrain the water from the fuel tank and bleed the air from the fuel system.

zIf the engine has not been started for more than one year, contact your Komatsu distributor to have engine overhauled.
