It belongs to a graded family in this run: 875485 is the same 8-application listing in the 0.25 mm undersize grade, while 875484 (standard), 875488 (0.25 mm undersize) and 875489 (0.50 mm undersize) are listed for 7 applications. Order by the grade stamped on the old shells and by the application list — the published weights do not separate a graded bearing set and must not be used to choose.\n\u003c\/p\u003e\n\u003ch2\u003e\n 🚤 Compatibility\n\u003c\/h2\u003e\n\u003cp\u003e\n Typically suits:\n\u003c\/p\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Volvo Penta MD1B\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta MD2B\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta MD3B\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta MD11C\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta MD11D\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta AQD2B\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta MD17C\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta MD17D\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n \u003cli\u003e\n  \u003cstrong\u003e\n   Engine Family:\n  \u003c\/strong\u003e\n  MD, AQD\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n ⚙️ Key Features\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Standard grade\n \u003c\/li\u003e\n \u003cli\u003e\n  0.152 kg\n \u003c\/li\u003e\n \u003cli\u003e\n  Listed for 8 applications across MD and AQD series engines\n \u003c\/li\u003e\n \u003cli\u003e\n  0.25 mm undersize equivalent on the same listing is 875485\n \u003c\/li\u003e\n \u003cli\u003e\n  Order by the stamped grade, not by weight\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔌 Function\n\u003c\/h2\u003e\n\u003cp\u003e\n Carries the crankshaft in the block, holding it on an oil film and taking the load from each firing stroke.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚠️ Common Signs of Failure\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Low or falling oil pressure, worst when hot at idle\n \u003c\/li\u003e\n \u003cli\u003e\n  Deep rumble from the bottom of the engine under load\n \u003c\/li\u003e\n \u003cli\u003e\n  Bearing material or copper flakes found in the sump or filter\n \u003c\/li\u003e\n \u003cli\u003e\n  Shells scored, wiped or showing the underlay through the surface\n \u003c\/li\u003e\n \u003cli\u003e\n  Crankshaft end float or journal clearance measuring beyond limits\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🛠️ Service Notes\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Read the grade stamped on the old shells and measure the journals before ordering — standard, 0.25 mm and 0.50 mm undersize are separate kits and mass is no guide to which is which\n \u003c\/li\u003e\n \u003cli\u003e\n  There are two standard-grade kits in this run, 875483 and 875484, distinguished by their application listings rather than by any note; confirm against your engine before ordering\n \u003c\/li\u003e\n \u003cli\u003e\n  Fit shells dry into clean housings, oil the running face only, and tighten to the specified sequence\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔄 Supersession \u0026amp; Cross Reference\n\u003c\/h2\u003e\n\u003ch3\u003e\n Aftermarket \/ Verified Equivalents\n\u003c\/h3\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Crom: 111464\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 📦 Condition\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Genuine Volvo Penta part\n \u003c\/li\u003e\n \u003cli\u003e\n  Brand new\n \u003c\/li\u003e\n \u003cli\u003e\n  Supplied in original or equivalent packaging\n \u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Volvo Penta","offers":[{"title":"Default Title","offer_id":53385493086500,"sku":"K627172","price":332.72,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/8115\/7924\/files\/original_5a667425-fb8d-4f26-b6f9-f96b167eaebe.jpg?v=1788103730","url":"https:\/\/www.sawleysautoandmarine.com.au\/products\/875483-main-bearing-kit-genuine-volvo-penta","provider":"Sawley's Auto and Marine","version":"1.0","type":"link"}
