Experience Supply Unit Lubrication of rail pumps failed Rail pumps replaced with correctly machined ones plus design changed > solved Servo oil connecting pipes to collector block cracked Connecting pipes replaced by flexible hoses > solved WCH Sales Kit 03May / 39 / RB
Experience Rail Unit Vibrations on upper platform Modified design for new engines > solved Rail valve connections broken Better quality assurance and slight modification on connectors > solved Insufficient accessibility of rail unit casing internals Accessibility vastly improved by new design > solved WCH Sales Kit 03May / 40 / RB
Experience Control System Malfunction of some sensors Sensors were defective or showed bad wiring > solved Valve drive module failures new print set-up for lower thermal stress of components > solved Regulating behaviour unsuitable for large swell and light ship Software control loops modified for compatibility > solved WCH Sales Kit 03May / 41 / RB
Experience Full Inspection 5300Rhrs Conventional Parts Very good results on liner wear Very good result on piston ring wear Very good load pattern on crankshaft gear wheel Clean valve seat Good injection nozzle shape WCH Sales Kit 03May / 42 / RB
Experience Specific Parts Full Inspection 5300Rhrs Very good load pattern on gear wheels of supply unit No wear on fuel cams No wear on hydraulic actuator for ExVa No wear on crank angle sensor assembly Electrically driven hydraulic pumps have been modified (couplings, vibs) Emergency pressure regulating valve has been modified (tightness) WCH Sales Kit 03May / 43 / RB
Experience Full Inspection 5300Rhrs Injection Control Unit Shows absolutely same injection pattern as when tested new No wear on sealing surface of injection control valve No wear on control oil piston No wear on injection control valve slide WCH Sales Kit 03May / 44 / RB
