In December 2016 GSE commenced a major workshop overhaul for YLEM Energy Ltd of an 8 Cylinder Perkins engine. The engine was due to be re-located and was due a major 70’000 hour overhaul.
The crankshaft was removed for specialist repair, due to undersize main and crankpin journals. The crank was ground throughout to – 0.25mm and refitted with OEM bearings and replacement damper.
The original cylinder heads were reworked, replacing valves, seats and guides. Connecting rods, cylinder liners and gear driven pumps were replaced with new OEM parts.
The workshop rebuild was completed with the engine lubricating oil system flushed on completion, along with a full re-spray, prior to being transported to Brook Hill Landfill site in Flintshire.
On completion of the rebuild, the engine was run-up to complete initial bearing runs and gradually stepped up at loaded increments up to 400kw to verify performance.
