It forms part of the glow plug installation hardware stack alongside the thrust sleeve, spring washer, and flange nut. Volvo Penta parts diagrams typically show one sealing ring per glow plug position on applicable engines.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCompatible Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVolvo Penta AD31L-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AD31P-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AD41L-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AD41P-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D41L-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TAMD31L-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TAMD31M-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TAMD31P-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TAMD31S-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TAMD41H-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TAMD41H-B\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TAMD41L-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TAMD41M-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TAMD41P-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TMD31L-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TMD41L-A\u003c\/li\u003e\n\u003cli\u003eAlso referenced for: AQAD31A, MD31A, TMD31B\u003c\/li\u003e\n\u003cli\u003eConfirm fitment by engine model, serial number, and glow plug assembly diagram before ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eEngine Family:\u003c\/strong\u003e Volvo Penta 31-series and 41-series marine diesel\u003cbr\u003e\u003cstrong\u003eSystem:\u003c\/strong\u003e Electrical — glow plug \/ cold-start system\u003cbr\u003e\u003cstrong\u003eDiagram Position:\u003c\/strong\u003e Glow plug assembly — sealing ring in the glow plug hardware stack (used with thrust sleeve 859328, spring washer 941905, and flange nut 965483)\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSerial Number Requirement\u003c\/strong\u003e\u003cbr\u003eConfirm the engine model, serial number, and glow plug assembly diagram before ordering.

Count the number of glow plugs in your engine to determine quantity. Most 31- and 41-series Volvo Penta diesels have 4 or 6 cylinders — order accordingly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need to replace the other glow plug hardware at the same time?\u003c\/strong\u003e\u003cbr\u003eIf the engine has significant hours or if the glow plug assembly is being fully serviced, inspect the thrust sleeve (859328), spring washer (941905), and flange nut (965483) at the same time. Replacing worn hardware together avoids reopening the assembly shortly after.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eParts Desk Insights\u003c\/strong\u003e\u003cbr\u003eThis sealing ring is most often needed when glow plugs are being replaced or inspected on higher-hour 31- and 41-series Volvo Penta diesel engines — particularly TAMD41 and TAMD31 variants in workboat and commercial applications. The most common oversight is ordering only the glow plug and skipping the sealing ring, which can result in a compromised seal on reassembly. Order one per cylinder. It is also worth having the thrust sleeve (859328) and spring washer (941905) on hand during the service call, as those components are in the same assembly and are inexpensive to replace preventively.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eRelated Parts\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/8131510730788\"\u003eVolvo Penta Sealing Ring 851407\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/8131489529892\"\u003eVolvo Penta Fuel Feed Pump Gasket 3501530 | OEM MD TMD TAMD KAD\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/8266776674340\"\u003eVolvo Penta Engine Overhaul Gasket Kit 11705955\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/8131513188388\"\u003eVolvo Penta Aftercooler Gasket 859196 – AQAD40 \/ TAMD40\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/8131513090084\"\u003eVolvo Penta Valve Cover Gasket 859120\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/8131474718756\"\u003eVolvo Penta Gasket 1545779 — OEM Marine Engine Seal\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564050546724,"sku":"859211","price":6.6,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/b30b79c5-9adf-4dc2-9cb4-7b5e27f85d4f.png?v=1788639388","url":"https:\/\/marisolmarine.com\/products\/volvo-1092","provider":"Marisol Marine Company","version":"1.0","type":"link"}
