{"product_id":"3806987-injection-pump-core-genuine-volvo-penta","title":"3806987 Injection Pump Core | Genuine Volvo Penta Part","description":"\u003ch2\u003e\n 🔧 Product Description\n\u003c\/h2\u003e\n\u003cp\u003e\n Core deposit for an injection pump, in the Fuel System group. It is the refundable charge raised against the old injection pump when the exchange unit is bought, and it comes back once the worn injection pump 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 3803987, which is the number to quote for the component itself. We list that number as an injection pump, reman. It is one of seven injection pump cores in this block. Five carry a published weight on the deposit line - 0.646 kg, 0.93 kg, 0.998 kg, 1.1 kg and 1.465 kg - and two, 3806900 and 3806950, carry none at all, so weight will not sort the set. Order by the paired exchange number. The deposit line carries a published weight of 1.1 kg, and the exchange pump 3803987 is listed at 1.077 kg. Injection pump cores 3806899 at 0.93 kg and 3806967 at 0.998 kg sit within 170 grams of it, so the three are not separable by weight - order by the exchange number.\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 injection pump you can fit\n \u003c\/li\u003e\n \u003cli\u003e\n  Belongs with the exchange unit, part number 3803987\n \u003c\/li\u003e\n \u003cli\u003e\n  Refunded when the old injection pump is returned\n \u003c\/li\u003e\n \u003cli\u003e\n  Published weight 1.1 kg\n \u003c\/li\u003e\n \u003cli\u003e\n  Within 170 g of injection pump cores 3806899 and 3806967\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 injection pump itself raises fuel to injection pressure and meters the quantity delivered to each cylinder, in time with the engine.\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 injection pump being exchanged\n \u003c\/li\u003e\n \u003cli\u003e\n  Hard starting, or the engine refusing to fire at all once it is hot\n \u003c\/li\u003e\n \u003cli\u003e\n  Power down, with the engine hunting or surging at a steady throttle\n \u003c\/li\u003e\n \u003cli\u003e\n  Black or white smoke at the exhaust, and the oil level creeping up as diesel gets past\n \u003c\/li\u003e\n \u003cli\u003e\n  Diesel weeping from the pump body or its drive-end seal, or timing that will no longer hold its setting\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 injection pump 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 3803987\n \u003c\/li\u003e\n \u003cli\u003e\n  Prove the fuel supply first, since a blocked filter, a collapsing suction hose or air drawn in on the lift side give the same symptoms as a tired pump, and have the timing set to the documented figure when the exchange pump goes on\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":53385594437924,"sku":"F222168","price":495.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/8115\/7924\/files\/original_99e1c00c-0c06-4c75-b992-093a0f621335.jpg?v=1788082577","url":"https:\/\/www.sawleysautoandmarine.com.au\/products\/3806987-injection-pump-core-genuine-volvo-penta","provider":"Sawley's Auto and Marine","version":"1.0","type":"link"}
