What does not carry forward automatically is the control setting: pressure cut-in, flow priority and the regulator arrangement were revised on some G-series builds. A pump that is physically identical and set up differently will fit, run, and leave the machine slow to tip. Confirm from the number cast on your pump and the machine serial prefix, not from the model letter alone.<\/p>\n<h2>\u0394\u03b9\u03ac\u03b3\u03bd\u03c9\u03c3\u03b7 \u03ba\u03b1\u03b9 \u03c4\u03bf\u03c0\u03bf\u03b8\u03ad\u03c4\u03b7\u03c3\u03b7<\/h2>\n<ul>\n<li>Judge the pump hot: hoist and tip times lengthen as oil temperature rises.<\/li>\n<li>\u0391\u03c0\u03bf\u03ba\u03bb\u03b5\u03af\u03c3\u03c4\u03b5 \u03c4\u03b9\u03c2 \u03c1\u03c5\u03b8\u03bc\u03af\u03c3\u03b5\u03b9\u03c2 \u03b1\u03bd\u03b1\u03ba\u03bf\u03cd\u03c6\u03b9\u03c3\u03b7\u03c2 \u03ba\u03b1\u03b9 \u03c4\u03b7 \u03b2\u03b1\u03bb\u03b2\u03af\u03b4\u03b1 \u03c3\u03c5\u03b3\u03ba\u03c1\u03ac\u03c4\u03b7\u03c3\u03b7\u03c2 \u03c4\u03bf\u03c5 \u03c3\u03ce\u03bc\u03b1\u03c4\u03bf\u03c2 \u03c0\u03c1\u03b9\u03bd \u03ba\u03b1\u03c4\u03b1\u03b4\u03b9\u03ba\u03ac\u03c3\u03b5\u03c4\u03b5 \u03c4\u03b7\u03bd \u03b1\u03bd\u03c4\u03bb\u03af\u03b1.<\/li>\n<li>Noise under load points at cavitation, so check the suction line and strainer.<\/li>\n<li>\u039a\u03b1\u03c4\u03ac \u03c4\u03b7\u03bd \u03c4\u03bf\u03c0\u03bf\u03b8\u03ad\u03c4\u03b7\u03c3\u03b7, \u03b1\u03bd\u03c4\u03b9\u03c3\u03c4\u03bf\u03b9\u03c7\u03af\u03c3\u03c4\u03b5 \u03c4\u03b7\u03bd \u03bf\u03b4\u03cc\u03bd\u03c4\u03c9\u03c3\u03b7 \u03c4\u03bf\u03c5 \u03ac\u03be\u03bf\u03bd\u03b1, \u03c4\u03bf\u03bd \u03bf\u03b4\u03b7\u03b3\u03cc, \u03c4\u03b7 \u03c6\u03bb\u03ac\u03bd\u03c4\u03b6\u03b1, \u03c4\u03b9\u03c2 \u03b8\u03ad\u03c3\u03b5\u03b9\u03c2 \u03b8\u03c5\u03c1\u03ce\u03bd \u03ba\u03b1\u03b9 \u03c4\u03bf\u03bd \u03c0\u03c1\u03bf\u03c3\u03b1\u03bd\u03b1\u03c4\u03bf\u03bb\u03b9\u03c3\u03bc\u03cc \u03b5\u03bb\u03ad\u03b3\u03c7\u03bf\u03c5 \u03bc\u03b5 \u03c4\u03b7\u03bd \u03b1\u03c6\u03b1\u03b9\u03c1\u03b5\u03b8\u03b5\u03af\u03c3\u03b1 \u03b1\u03bd\u03c4\u03bb\u03af\u03b1, \u03b3\u03b5\u03bc\u03af\u03c3\u03c4\u03b5 \u03bc\u03b5 \u03ba\u03b1\u03b8\u03b1\u03c1\u03cc \u03bb\u03ac\u03b4\u03b9 \u03c0\u03c1\u03b9\u03bd \u03b1\u03c0\u03cc \u03c4\u03b7 \u03c3\u03c4\u03c1\u03bf\u03c6\u03ac\u03c1\u03b9\u03c3\u03bc\u03b1, \u03b1\u03bb\u03bb\u03ac\u03be\u03c4\u03b5 \u03c4\u03bf \u03c3\u03c4\u03bf\u03b9\u03c7\u03b5\u03af\u03bf \u03c4\u03bf\u03c5 \u03c6\u03af\u03bb\u03c4\u03c1\u03bf\u03c5 \u03b5\u03c0\u03b9\u03c3\u03c4\u03c1\u03bf\u03c6\u03ae\u03c2, \u03b4\u03b9\u03b1\u03c4\u03b7\u03c1\u03ae\u03c3\u03c4\u03b5 \u03c4\u03b7\u03bd \u03b1\u03c0\u03bf\u03c3\u03c4\u03c1\u03ac\u03b3\u03b3\u03b9\u03c3\u03b7 \u03ba\u03ac\u03c1\u03c4\u03b5\u03c1 \u03c7\u03c9\u03c1\u03af\u03c2 \u03c0\u03b5\u03c1\u03b9\u03bf\u03c1\u03b9\u03c3\u03bc\u03cc \u03c0\u03c1\u03bf\u03c2 \u03c4\u03b7 \u03b4\u03b5\u03be\u03b1\u03bc\u03b5\u03bd\u03ae \u03ba\u03b1\u03b9 \u03c3\u03c4\u03bf\u03c7\u03b5\u03cd\u03c3\u03c4\u03b5 ISO 4406 18\/16\/13.<\/li>\n<\/ul>\n<p>\u039f\u03b9 <a href=\"https:\/\/www.hongtengdaparts.com\/el\/%ce%b5%ce%b3%cf%87%ce%b5%ce%b9%cf%81%ce%af%ce%b4%ce%b9%ce%bf-%cf%80%cf%81%ce%bf%ce%b4%ce%b9%ce%b1%ce%b3%cf%81%ce%b1%cf%86%cf%8e%ce%bd-%ce%b3%ce%b9%ce%b1-%ce%b1%ce%b3%ce%bf%cf%81%ce%b1%cf%83%cf%84\/\">\u03b1\u03b3\u03bf\u03c1\u03b1\u03c3\u03c4\u03ae\u03c2 \u03b1\u03bd\u03c4\u03bb\u03b9\u03ce\u03bd \u03ba\u03b1\u03b9 \u03bf \u03bf\u03b4\u03b7\u03b3\u03cc\u03c2 \u03c0\u03c1\u03bf\u03b4\u03b9\u03b1\u03b3\u03c1\u03b1\u03c6\u03ce\u03bd \u03bc\u03b1\u03c2<\/a> \u03ba\u03b1\u03bb\u03cd\u03c0\u03c4\u03b5\u03b9 \u03c4\u03bf\u03bd \u03c4\u03c1\u03cc\u03c0\u03bf \u03c3\u03cd\u03b3\u03ba\u03c1\u03b9\u03c3\u03b7\u03c2 \u03b5\u03bd\u03cc\u03c2 \u03b1\u03bd\u03c4\u03b1\u03bb\u03bb\u03b1\u03ba\u03c4\u03b9\u03ba\u03bf\u03cd \u03bc\u03b5 \u03c4\u03bf \u03c0\u03c1\u03c9\u03c4\u03cc\u03c4\u03c5\u03c0\u03bf, \u03ba\u03b1\u03b9 <a href=\"https:\/\/www.hongtengdaparts.com\/el\/%ce%ba%ce%b9%cf%84-%cf%83%cf%84%ce%b5%ce%b3%ce%b1%ce%bd%ce%bf%cf%80%ce%bf%ce%af%ce%b7%cf%83%ce%b7%cf%82-%cf%85%ce%b4%cf%81%ce%b1%cf%85%ce%bb%ce%b9%ce%ba%ce%ae%cf%82-%ce%b1%ce%bd%cf%84%ce%bb%ce%af\/\">\u03c4\u03b7 \u03bb\u03af\u03c3\u03c4\u03b1 \u03b5\u03bb\u03ad\u03b3\u03c7\u03bf\u03c5 \u03b1\u03bd\u03b1\u03ba\u03b1\u03c4\u03b1\u03c3\u03ba\u03b5\u03c5\u03ae\u03c2 \u03ba\u03b9\u03c4 \u03c3\u03c4\u03b5\u03b3\u03b1\u03bd\u03bf\u03c0\u03bf\u03af\u03b7\u03c3\u03b7\u03c2<\/a> covers what a proper rebuild should include.<\/p>\n<h2>\u03a0\u03b1\u03c1\u03b1\u03b3\u03b3\u03b5\u03bb\u03af\u03b1<\/h2>\n<p>Minimum order one piece.
