PISTON OVERHAUL:

GENERAL PROCEDURE FOR WITHDRAWING THE PISTON

- The engine is isolated and locked off on LO, FO, CW and start air. Turning gear is engaged and the engine CW jackets are drained down to the extent necessary.

BEFORE COMMENCING OVERHAUL:

- Starting air shut off and locked off.

- Open the indicator cocks.

- Engine cooled down sufficiently to allow LO pumps to be shut down.

- Isolate fuel and cooling water.

- Confirm required spares are on board.

- Check that lifting tools, strops, shackles etc are within certification and in good order.

- Check that jacks are in good condition with no leaks.

- Ensure permission for immobilization is given.

- Carry out risk assessment.

- Ventilate crankcase and obtain permit to work.

- Ensure that no-one else is working elsewhere on the engine (e.g. cleaning the scavenge space)

- Check that no-one is working in the vicinity of the shafting system, and that the bridge has confirmed that it is OK to turn the engine on Turning (Propeller Clearance)

AT THE COMMENCEMENT OF THE OVERHAUL

- Drain cylinder cooling water from respective cylinder. NOTE: It is not advisable to just drain down to liner level in case the liner is disturbed when lifting the piston.

- Inspect Shaft Condition: The next step is to inspect the condition of the main engine’s shaft. The inspection involves opening the cover and conducting a thorough check to ensure there is no damage or wear.

- Remove Cylinder Head: The cylinder head needs to be removed to access the engine’s internal components. Our experienced technicians will disconnect all connections and observe the area carefully before lifting to ensure absolute safety. After the cylinder head is removed, we conduct cleaning and inspection.

- Remove Piston and Connecting Rod: We then remove the piston and connecting rod for cleaning and inspection. This process involves cleaning the piston, measuring and inspecting the oil scraper ring groove for wear, and replacing all piston rings.

- Crown piston and Gudgeon Pin: In this step, we clean, measure and replace the crown piston, gudgeon pin and bushing if necessary.

- Reassemble: Once all the parts have been cleaned, measured, and replaced, we reassemble the engine with precision, ensuring all connections and components are properly installed.
