It is the refundable charge raised against the old upper gear when the exchange unit is bought, and it comes back once the worn upper gear is returned. The line itself is an accounting entry rather than a part, so nothing ships against it on its own. Under Volvo Penta's core numbering the exchange unit it belongs to takes part number 3801931, which is the number to quote for the component itself. It is the only upper gear core in this block, so there is nothing here to confuse it with.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚙️ Key Features\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Core deposit line, not an upper gear you can fit\n \u003c\/li\u003e\n \u003cli\u003e\n  Belongs with the exchange unit, part number 3801931\n \u003c\/li\u003e\n \u003cli\u003e\n  Refunded when the old upper gear is returned\n \u003c\/li\u003e\n \u003cli\u003e\n  The only upper gear core in this block\n \u003c\/li\u003e\n \u003cli\u003e\n  Marine Propulsion group\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔌 Function\n\u003c\/h2\u003e\n\u003cp\u003e\n As a line item it carries the refundable core charge on the exchange; the upper gear itself takes the drive from the engine through the transom and turns it down towards the lower unit, carrying its own gearset, bearings and seals.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚠️ Common Signs of Failure\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the upper gear being exchanged\n \u003c\/li\u003e\n \u003cli\u003e\n  Whine or growl from the top of the leg that rises and falls with engine speed\n \u003c\/li\u003e\n \u003cli\u003e\n  Milky or grey oil at the drain, or water standing in the leg after a season afloat\n \u003c\/li\u003e\n \u003cli\u003e\n  Stiff, noisy or incomplete shifting between ahead and astern\n \u003c\/li\u003e\n \u003cli\u003e\n  Vibration through the transom, or play found at the input\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  The charge is refunded when the worn upper gear is returned, so keep the old unit and send it back rather than scrapping it\n \u003c\/li\u003e\n \u003cli\u003e\n  Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3801931\n \u003c\/li\u003e\n \u003cli\u003e\n  Find out how the water got in before the exchange unit goes on, since a perished bellows or a cut seal will drown the replacement in the same way\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 📦 Condition\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Refundable core deposit - not a physical part\n \u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Volvo Penta","offers":[{"title":"Default Title","offer_id":53385772040484,"sku":"1596157","price":11000.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/8115\/7924\/files\/original_c7476de8-8688-43f0-8047-b1e44347ebb4.jpg?v=1788076494","url":"https:\/\/www.sawleysautoandmarine.com.au\/products\/3804931-upper-gear-core-genuine-volvo-penta","provider":"Sawley's Auto and Marine","version":"1.0","type":"link"}
