The cylinder A6 was replaced by new short cylinder liner , All cylinder liners measured were taken any of they were over wear… but the old cylinder liner A6 was left for spare and it can be used only in extreme emergency due a lot of corrosion in the cylinder liner collar. See bottom the measurement report.

5) Disconnected cylinder liner and cylinder head A6: these pulled out together, due to the cylinder had high water leakage and hard corrosion in the cylinder liner collar. Our team avoid to transfer this unit to our workshop and done it disconnection on site.

6) Was Rented an external Cylinder liner honing machine: to hone the Cylinder Liners (A3, A6, B1, B5, B6, Spare #1, Spare #2). Cylinder liners honing were done.

Inspected and cleaned oil spaces. Pulled, inspected and cleaned. Checked the height of the ring grooves, use form No. 3211V016. Checked the retainer rings of the gudgeon pins. Replaced complete set of piston rings. The piston B6 has over wear in the first piston crown groove it was replaced by reconditioned one that ship had in spare. See bottom the Measurement report. When the piston A3 was taken out appeared the first piston ring broken.

8) Connecting rods (A3, A6, B1, B5, B6): Replaced big end bearings. Inspected mating surface serrations. Measured the big end bore, used form No. 3211V015. Inspected the small end bearings. Were replaced the screws of connecting rod A6. See measurement report below. The connecting rod big end bearings B6 was found with deep peel.
