The key identification point is its location at the flywheel-to-coupler stud connection in the flywheel housing assembly. This is a small, low-cost part that is easy to overlook during service, but it plays an important role in securing the flywheel-to-coupler connection. If you’re servicing the flywheel or flexible coupling on a 4.3L, 7.4L, or 8.2L Volvo Penta gasoline engine, it’s worth replacing this retainer as a matter of course rather than reusing the old one.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43563992580132,"sku":"22746891","price":5.6,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/6c49ef74-060d-44fa-9bbd-20c1d4b0dbc0.png?v=1787510402","url":"https:\/\/marisolmarine.com\/products\/volvo-309","provider":"Marisol Marine Company","version":"1.0","type":"link"}
