{"product_id":"3806964-injector-core-genuine-volvo-penta","title":"3806964 Injector Core | Genuine Volvo Penta Part","description":"\u003ch2\u003e\n 🔧 Product Description\n\u003c\/h2\u003e\n\u003cp\u003e\n Core deposit for an injector, in the Fuel System group. It is the refundable charge raised against the old injector when the exchange unit is bought, and it comes back once the worn injector 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 3803964, which is the number to quote for the component itself. We list that number simply as an injector, with no exchange or remanufactured wording against it. It is one of eighteen injector cores running through this block, and five of those publish no weight at all, so no ranking by mass can be made across the set. The deposit line reads 0.544 kg, which is 1.2 pounds to the gram and is the heaviest figure published against any of the plain injector cores here, though with five of them unweighted that ranking covers only the thirteen that carry a figure. The exchange counterpart 3803964 is listed at 0.204 kg, and its heading carries no exchange or remanufactured wording, so the two published masses do not agree and neither should be treated as a shipping weight.\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 injector you can fit\n \u003c\/li\u003e\n \u003cli\u003e\n  Belongs with the exchange unit, part number 3803964\n \u003c\/li\u003e\n \u003cli\u003e\n  Refunded when the old injector is returned\n \u003c\/li\u003e\n \u003cli\u003e\n  Published weight 0.544 kg, exactly 1.2 lb\n \u003c\/li\u003e\n \u003cli\u003e\n  The heaviest of the thirteen weighted injector cores here\n \u003c\/li\u003e\n \u003cli\u003e\n  Exchange counterpart 3803964 carries no reman or exchange wording\n \u003c\/li\u003e\n \u003cli\u003e\n  Fuel System 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 injector itself atomises fuel into the combustion chamber at the pressure and timing the engine's fuelling demands.\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 injector being exchanged\n \u003c\/li\u003e\n \u003cli\u003e\n  A rough idle with one cylinder plainly doing less work than the rest\n \u003c\/li\u003e\n \u003cli\u003e\n  Black smoke, a smell of unburnt diesel and fuel consumption climbing\n \u003c\/li\u003e\n \u003cli\u003e\n  A hard knock or rattle from one cylinder that sharpens as the engine warms\n \u003c\/li\u003e\n \u003cli\u003e\n  Back-leakage over specification, or a nozzle found dribbling rather than atomising on test\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 injector 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 3803964\n \u003c\/li\u003e\n \u003cli\u003e\n  Injectors are normally changed as a set, since one new one alongside worn neighbours will not settle the running, and the copper seat washer and clamp fixings should be treated as single-use\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":53385489645860,"sku":"714839T","price":165.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/8115\/7924\/files\/original_daff4637-29d2-4e79-be9f-24af524e8868.jpg?v=1788081925","url":"https:\/\/www.sawleysautoandmarine.com.au\/products\/3806964-injector-core-genuine-volvo-penta","provider":"Sawley's Auto and Marine","version":"1.0","type":"link"}
