{"product_id":"volvo-648","title":"Volvo Penta Raw Water Pump Impeller Puller Screw 3843949","description":"\u003cp\u003eVolvo Penta 3843949 is a genuine OEM puller screw used as an impeller removal tool for select Volvo Penta diesel raw-water pump applications. Current parts sources consistently identify it as a puller screw, and stronger application references describe it as an impeller puller that threads into the impeller to remove it from the pump housing without damaging the housing during service.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Volvo Penta OEM part number \u003cstrong\u003e3843949\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eIdentified as a \u003cstrong\u003epuller screw \/ impeller removal tool\u003c\/strong\u003e for Volvo Penta service use.\u003c\/li\u003e\n\u003cli\u003eDesigned to remove the impeller without damaging the water pump housing.\u003c\/li\u003e\n\u003cli\u003eCommonly associated with impellers \u003cstrong\u003e24139373\u003c\/strong\u003e, \u003cstrong\u003e21951358\u003c\/strong\u003e, and \u003cstrong\u003e22994993\u003c\/strong\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eEngine Compatibility\u003c\/h2\u003e\n\u003cp\u003eThe strongest supportable fitment for 3843949 is with later Volvo Penta \u003cstrong\u003eD6\u003c\/strong\u003e diesel raw-water pump service and certain \u003cstrong\u003eTAMD63\u003c\/strong\u003e applications.

Because this is a service tool matched to the impeller and pump setup, the safest fitment path is to verify the impeller part number and engine serial number before ordering.\u003c\/p\u003e\n\u003ch2\u003eSerial Number Fitment Notice\u003c\/h2\u003e\n\u003cp\u003eMatch Volvo Penta part number \u003cstrong\u003e3843949\u003c\/strong\u003e to your engine serial number and, even more importantly, to the correct impeller part number before ordering.

It is most useful when removing larger raw-water pump impellers where pry removal could damage the pump housing. This service guidance is supported by current product descriptions describing it as the proper impeller extraction tool.\u003c\/p\u003e\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eThread the puller screw into the internal threads of the impeller, then continue the extraction process using the pump shaft as resistance to press the impeller out. Use it only on compatible threaded impellers, since one current source notes that non-genuine impellers may not have the required internal thread.\u003c\/p\u003e\n\u003ch2\u003eAlternate\/Superseded Part Numbers\u003c\/h2\u003e\n\u003cp\u003eThe reviewed sources continue to list \u003cstrong\u003e3843949\u003c\/strong\u003e as the active Volvo Penta OEM number.

Using the correct puller screw usually saves the pump housing, especially on larger Volvo Penta diesel impellers that can be stubborn after time in service.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e Ships same or next day for fast Canada wide shipping. ⚓\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564016271396,"sku":"3843949","price":49.9,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/37d9fd68-a297-4646-b92e-49729f929fb2.png?v=1776479535","url":"https:\/\/marisolmarine.com\/products\/volvo-648","provider":"Marisol Marine Company","version":"1.0","type":"link"}
