Piston/Connecting Rod Assembly Minimum oil consumption Perfect sealing and low oil consumption due to 3 compression and 2-oil is ensured by providing three scrapper rings on each aluminium piston. compression rings & two oil scraper 9 The nodular iron connecting rod is drilled through for pressure lubrication rings per piston - thus minimising oil of the piston pin through discharge gas line Steel backed white metal shells on big end and bronze bearing on small end of connecting rod. The complete assembly can be removed from the top for servicing without withdrawing the cylinder liner Cylinder Liner and Suction Valve Interchangeable cylinder liners are made of fine-grained, centrifugally cast, alloy iron. Fine boring and honing results in a mirror smooth running surface. A hydraulic mechanical suction valve lifting mechanism on each individual cylinder achieves loading and unloading. For unloading, the suction valve ring is lifted from its seat in the cylinder collar Kirloskar Genuine Spares and User by spring tension. Admitting controlled oil pressure to the control piston, allowing the suction valve ring to descend on its seat effects loading or cylinder. Friendly Spares Kits in Blue preprinted Cartons & Pouches with 3D Hologram Welded Steel Crankcase Low in weight, Rapid heat dissipation, Gas tight and impact proof Smooth internal surfaces Lubrication System & Filter guarantee the good oil condition. Forced lubrication by a gear pump, driven directly by the Crankshaft. The Pump incorporates a differential pressure regulator to provide separate pressures for two oil systems: lubrication system and control oil system. Automatically operating hydraulic delay valve ensures complete unloaded start. A metal gauze suction filter element and a throwaway discharge paper filter cartridges are provided for excellent filtering capacity of the lubricating oil Kirloskar Genuine Spares with 3D hologram. Crankshaft and Main Bearings Bearing surfaces of the high quality nodular cast iron crankshaft are groundto fine tolerances. Main bearings are white metal lined steel backed bushes, pressed into the cast iron bearing covers. Intermediate bearing blocks are provided with split type bearing shell of the same type. Each crankshaft is dynamically balanced together with the counter weights.
