MAINTENANCE OF TURBOCHARGER
2/4
ATTENTION
If you find any fault during this inspection, you will have to check the turbocompressor completely
in order to solve the problem. In this event, ask Kohler for the instruction manual specific to the
turbocompressor that needs overhauling or have the turbocompressor checked by one of Kohler official
or authorised Repair Shop.
After assembling the turbocompressor, do the following:
-
Check the turbo assembly and connections for security problems and air or lubricant leaks.
-
Check the manifold connections to the turbine as well as the exhaust manifold gasket.
-
Remove the oil drainage tube from the turbo. Look if there is oil inside and check the oil circuit for proper
operation (if your engine comes with a pre-lubrication system, you can use it). Once you have finished the
inspection, refit the drainage tube.
-
Lubricate the new turbos before starting them. To do so, add oil into the oil inlet and turn the turbo by
hand a few revolutions.
-
Verify that lube oil is clean and that the oil strainers are in good working conditions.
After starting the engine, do the following:
-
Refrain from increasing the load excessively, while the coolant temperature in the fresh water circuit
remains below 37ºC.
-
Test the engine under full loaded conditions.
-
Inspect all air, oil and exhaust gas pipes for leaks.
-
Check the turbochargers for unusual noise or vibration when the engine runs at rated load and output. If
noting any excessive noise or vibration, stop the engine immediately and contact your local Kohler
Technical Assistance Service.
-
Keep the engine idling for 3 or 4 minutes before shutting it off.
