It forms part of the rotating compressor\/turbine system, converting exhaust energy into compressed intake air while relying on a clean, stable oil supply.<\/p>\n<p>Exhaust-driven charging is a system, not just one hardware item. If a compressor wheel is clean but the engine still struggles under load, check the intake filter, charge-air hoses, exhaust restriction and oil supply before assuming this component has failed. A correct physical match also depends on the engine-specific inlet and outlet interfaces.<\/p>\n<h2 style=\"text-align:left!important;margin-left:0!important;margin-right:0!important;padding-left:0!important;clear:both!important;\">Key Product Features<\/h2>\n<ul>\n<li>CAT calls this an Engine Turbocharger Cartridge<\/li>\n<li>Public application list includes C9.3 marine and generator arrangements<\/li>\n<li>CAT lists ductile iron in material information<\/li>\n<li>Separate CAT Reman alternative 30R-0487 is listed on the manufacturer page<\/li>\n<\/ul>\n<h2 style=\"text-align:left!important;margin-left:0!important;margin-right:0!important;padding-left:0!important;clear:both!important;\">Teknik \u00d6zellikler<\/h2>\n<table class=\"ruipo-tech-table\" style=\"display:table!important;float:none!important;clear:both!important;position:static!important;width:100%!important;max-width:100%!important;min-width:0!important;margin:12px 0 22px 0!important;box-sizing:border-box!important;border-collapse:collapse!important;border-spacing:0!important;table-layout:fixed!important;text-align:left!important;font-size:14px;overflow-wrap:anywhere!important;\">\n<thead>\n<tr>\n<th style=\"text-align:left;border-bottom:1px solid #cbd5e1;background:#f0f3f8;padding:10px 12px;\">\u015eartname<\/th>\n<th style=\"text-align:left;border-bottom:1px solid #cbd5e1;background:#f0f3f8;padding:10px 12px;\">Detaylar<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"text-align:left;border-bottom:1px solid #d9e2eb;padding:9px 12px;vertical-align:top;\">Brand \/ part identification<\/td>\n<td style=\"text-align:left;border-bottom:1px solid #d9e2eb;padding:9px 12px;vertical-align:top;\">Caterpillar \/ 439-1331<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align:left;border-bottom:1px solid #d9e2eb;padding:9px 12px;vertical-align:top;\">Part number without hyphen<\/td>\n<td style=\"text-align:left;border-bottom:1px solid #d9e2eb;padding:9px 12px;vertical-align:top;\">4391331<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align:left;border-bottom:1px solid #d9e2eb;padding:9px 12px;vertical-align:top;\">Product type<\/td>\n<td style=\"text-align:left;border-bottom:1px solid #d9e2eb;padding:9px 12px;vertical-align:top;\">Engine turbocharger cartridge<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align:left;border-bottom:1px solid #d9e2eb;padding:9px 12px;vertical-align:top;\">Par\u00e7a numaras\u0131<\/td>\n<td style=\"text-align:left;border-bottom:1px solid #d9e2eb;padding:9px 12px;vertical-align:top;\">439-1331<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align:left;border-bottom:1px solid #d9e2eb;padding:9px 12px;vertical-align:top;\">Product type<\/td>\n<td style=\"text-align:left;border-bottom:1px solid #d9e2eb;padding:9px 12px;vertical-align:top;\">Engine Turbocharger Cartridge<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align:left;border-bottom:1px solid #d9e2eb;padding:9px 12px;vertical-align:top;\">CAT material<\/td>\n<td style=\"text-align:left;border-bottom:1px solid #d9e2eb;padding:9px 12px;vertical-align:top;\">Ductile (spheroidal) iron; metal compounds<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align:left;border-bottom:1px solid #d9e2eb;padding:9px 12px;vertical-align:top;\">CAT Reman alternative<\/td>\n<td style=\"text-align:left;border-bottom:1px solid #d9e2eb;padding:9px 12px;vertical-align:top;\">30R-0487 (separate product)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><em>Technical data above is limited to publicly verifiable CAT product information.

Inspection should include the adjacent parts, installation condition and available equipment diagnostics so that a new part is not installed into an unresolved system fault.<\/p>\n<h2 style=\"text-align:left!important;margin-left:0!important;margin-right:0!important;padding-left:0!important;clear:both!important;\">Installation and Maintenance Notes<\/h2>\n<ul>\n<li>Confirm shaft\/rotor and housing compatibility; avoid exposing open housings to loose particles.<\/li>\n<li>Restore clean lubrication and inspect adjacent gaskets and connections before startup.<\/li>\n<\/ul>\n<p>Turbocharger work demands clean lubrication and contamination control. A replacement cartridge or complete turbo must be matched to the installed arrangement; mixing visually similar units can create boost, mounting or cooling problems. Use the applicable Caterpillar service manual for torque figures, clearance settings, calibration instructions and safe test procedures; those values can differ between engine arrangements.<\/p>\n<h2 style=\"text-align:left!important;margin-left:0!important;margin-right:0!important;padding-left:0!important;clear:both!important;\">Sipari\u015f Vermeden \u00d6nce<\/h2>\n<ul>\n<li>Make clear that 439-1331 is the cartridge core, not necessarily a complete turbocharger assembly.<\/li>\n<li>Use C9.3 engine serial number to confirm installed arrangement.<\/li>\n<li>Please send the requested quantity, shipping destination, engine or machine serial number, and photographs of the old part or packaging if available.<\/li>\n<\/ul>\n<h2 style=\"text-align:left!important;margin-left:0!important;margin-right:0!important;padding-left:0!important;clear:both!important;\">\u0130lgili CAT Par\u00e7alar\u0131<\/h2>\n<p>For other components used in related engine or maintenance systems, review these RUIPO product listings.
