January 2017, GSE completed a minor overhaul of a Jenbacher 3 Series generator, installed at Highfield landfill site, operated by Cory Environmental ltd.
During a 5 day shutdown period, an overhaul schedule was undertaken that included removal of cylinder heads, pistons, connecting rods and cylinder liners. Along with removal of the turbocharger, aftercooler and crankshaft damper.
The original set of connecting rods was re-conditioned, to replace SE bushes and re-certify running tolerances. New pistons and ring packs were installed onto original connecting rods and re-fitted with new LE bearings, complete with a spare set of re-worked cylinder heads.
Finally the original Turbocharger and Aftercooler were re-fitted to the engine following subsequent overhaul. Finally a new OEM supply crankshaft damper was assembled to the engine.
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.
