{"product_id":"volvo-1036","title":"Volvo Penta Pretensioning Sleeve 853484","description":"\u003cp\u003eVolvo Penta 853484 is a genuine pretensioning sleeve used in older Volvo Penta sterndrive upper gear unit applications. Current Volvo Penta parts references identify it specifically as a pretensioning sleeve, and current schematic-based references place it in the upper gear unit assembly rather than an engine-side service group. Public application references consistently point to legacy Volvo Penta drive service use where correct gear-unit hardware fitment matters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Volvo Penta OEM part number 853484.\u003c\/li\u003e\n\u003cli\u003eIdentified by current sources as a pretensioning sleeve.\u003c\/li\u003e\n\u003cli\u003eCurrent schematic references place it in the upper gear unit.\u003c\/li\u003e\n\u003cli\u003eSold as an individual service part rather than a hardware kit.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eEngine Compatibility\u003c\/strong\u003e\u003cbr\u003eCurrent reviewed public references point to sterndrive compatibility rather than direct engine-family fitment. The clearest application signal places Volvo Penta 853484 in the \u003cstrong\u003eupper gear unit \/ upper housing\u003c\/strong\u003e group on older Volvo Penta marine drives. Because public fitment sources for this exact part number are limited and schematic-driven, fitment should be confirmed by exact drive model, upper gear unit layout, and serial number before ordering.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSerial Number Fitment Notice\u003c\/strong\u003e\u003cbr\u003eUpper gear unit service parts can vary by drive generation, housing style, and related internal hardware. Confirm Volvo Penta 853484 by drive serial number and by matching the exploded-view position in the correct upper gear unit parts diagram before ordering. Volvo Penta continues to list 853484 as an active genuine part number.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhen This Part Needs Replacement\u003c\/strong\u003e\u003cbr\u003eThis part is typically replaced during upper gear unit service when the original sleeve is worn, damaged, distorted, missing, or no longer suitable for correct reassembly and preload-related fitment. Because it is an upper-gear-unit service component, replacement is most commonly tied to teardown or rebuild work rather than routine maintenance. This use guidance is a service-based inference supported by the part's placement in upper gear unit schematics.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation Notes\u003c\/strong\u003e\u003cbr\u003eInstall only after confirming the exact drive model and upper gear unit diagram. Compare the replacement sleeve directly to the original part removed from the assembly, and inspect related internal gear-unit components during service so the sleeve is fitted into the correct hardware stack. For legacy sterndrive internals, diagram confirmation and serial-number verification are the safest checkpoints before final assembly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003cbr\u003eCurrent reviewed references identify \u003cstrong\u003e853484\u003c\/strong\u003e as the active Volvo Penta number for this pretensioning sleeve. Some current market listings also use the format \u003cstrong\u003e853484-4\u003c\/strong\u003e in the same application family. Current confirmed ordering number is \u003cstrong\u003e853484\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003cbr\u003eFor internal sterndrive parts like 853484, the most useful buying checkpoint is the \u003cstrong\u003eexact upper gear unit diagram position\u003c\/strong\u003e, not the part name alone. Pretensioning sleeves are specialized internal components, so serial-number matching and exploded-view confirmation are the best way to avoid ordering the wrong sleeve for a legacy Volvo Penta drive.\u003c\/p\u003e\n\u003cp\u003eShipping: Ships same or next day for fast Canada wide shipping. ⚓\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564047859748,"sku":"853484","price":60.6,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/117e9d91-b1ed-41b9-bbbb-252bffbe6266.png?v=1776045859","url":"https:\/\/marisolmarine.com\/products\/volvo-1036","provider":"Marisol Marine Company","version":"1.0","type":"link"}
