Prior to further tasks, inspect the complete engine for leaks. On the underside
of the water pump a leakage bore is located.
An oily leakage bore indicates a defective oil seal, which has to be renewed.
In case of emergence of water the rotary seal has to be removed. See chapter
13.3.
Inspect fuel lines, joints and connections. Look for scuffing marks.
Check oil feed line from oil tank to oil cooler and to the engine, as well as return
line from crankcase to oil tank. Additionally, check all oil transfer lines i.e. from
the main oil pump to oil inlet flange of hydraulic governor, from main oil pump
to the turbocharger and from turbo charger to suction pump.
Inspect coolant hoses, their connections and screw plugs for tightness.
Check surroundings for leaks!
At signs of operating media leaks find the reason and provide for remedy.
ATTENTION: Avoid overstressing of fastening elements.
Inspect all hoses, especially in the area of hose clamps and hose connections
for porosity, damages or kinks. If damage is noticed, renew hose immediately.
Inspect each attachment point of engine suspension frame.
Inspect the immediate surrounding of the attachment points on engine and
gearbox. Discoloration (black ring) around the attachment point indicates
abrasion caused by loose connection.
Check nuts and screws attaching external components for tight fit. For
tightening torques refer to the relevant chapter. Verify wire securing, renew as
required.
