This hydraulic cylinder seal kit is intended to restore reliable sealing performance within the dump cylinder, helping prevent hydraulic oil leakage and maintain the hydraulic pressure required for controlled bucket dumping. Manufactured from high-quality sealing materials, it provides dependable performance in demanding construction, quarrying, mining and heavy material handling applications.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe dump hydraulic cylinder controls the forward tilting and dumping movement of the wheel loader bucket, allowing operators to discharge materials efficiently into trucks, stockpiles, hoppers and other locations. Continuous exposure to high hydraulic pressures, heavy payloads and repeated operating cycles gradually wears cylinder sealing components. Damaged or worn seals can result in external hydraulic oil leakage, slow bucket dumping, reduced hydraulic force, bucket drift and internal pressure bypass. Replacing the appropriate seal kit can help restore hydraulic efficiency, maintain cylinder pressure and improve loader productivity while reducing unplanned maintenance downtime.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003e\u003cspan\u003eTypical Applications\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eConstruction • Earthmoving • Mining • Quarrying • Aggregate Handling • Material Handling • Road Construction • Loading Operations\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003e\u003cspan\u003eCommon Symptoms\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-spread=\"false\"\u003e\n\u003cli\u003e\u003cspan\u003eHydraulic oil leakage from the dump cylinder\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSlow bucket dumping\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eReduced dump cylinder force\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eBucket drifting during operation\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eInternal hydraulic pressure bypass\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDifficulty maintaining bucket position\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eReduced hydraulic system efficiency\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003e\u003cspan\u003eCross-Reference Part Numbers\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003e\u003cspan\u003eOEM Part Number:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e 707-99-73020\u003c\/span\u003e\u003cstrong\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003e\u003cspan\u003eCompatible Models\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003e\u003cspan\u003eWheel Loaders:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Komatsu WA400-3, WA420-3.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003e\u003cspan\u003eFitment Note\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003ePlease verify the OEM part number, machine model, serial number and \u003c\/span\u003e\u003cstrong\u003e\u003cspan\u003edump hydraulic cylinder assembly\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e before ordering.
