It is also recommended as a precautionary replacement during any adjacent front-end engine service if the original fastener has been removed and shows visible wear or deformation.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eConfirm the part number and diagram position before installation. Inspect the related pulley, vibration damper, and fastening surfaces at the same time to avoid repeat front-end hardware issues after service. Torque to Volvo Penta specification for this position.\u003c\/p\u003e\n\n\u003ch2\u003eParts Desk Insights\u003c\/h2\u003e\n\u003cp\u003eThis is one of those parts that looks simple but causes real headaches when the wrong fastener goes in. The most common issue we see is customers trying to match by thread size and wrench fit rather than by diagram position — the front-end of these engines can have several similar-looking nuts in close proximity. Ordering by part number and confirming against your serial number is the right call here. Best used as a direct OEM replacement during front-end engine service, vibration damper R\u0026amp;R, or crankshaft pulley work.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43563998543908,"sku":"3531111","price":11.6,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/download_0c75e420-a910-4813-a6c5-c1acbe3abb19.jpg?v=1776454497","url":"https:\/\/marisolmarine.com\/products\/volvo-penta-crankshaft-damper-pulley-nut-3531111","provider":"Marisol Marine Company","version":"1.0","type":"link"}
