OVERHAUL PRECAUTIONS


Mumbai, Monday, March 3rd, 2003

As a once-a-week routine, the main air compressor both LP & suction discharge valves were replaced with overhauled ones. On the overhauled LP suction valve assembly, the split pin for the locking nut was not put in place.

While the compressor was running (after overhaul of valves) the nut got slack and fell on top of LP piston causing damage to the piston liner.

The damaged parts were renewed and strict instructions given to engineers to ensure proper refits of LP & HP suction and discharge values to avoid repetition of this kind.
