It is a precision steering-system component — not a generic engine accessory pulley — and matching it to the original OEM number and pump assembly is essential.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon customer issue:\u003c\/strong\u003e Buyers occasionally confuse this pulley with other accessory-drive pulleys on the same engine. Cross-reference the Volvo Penta steering diagram and confirm the part number on your existing pump before ordering. If your engine still shows 3862700 in service records, 3888078 is the current OEM replacement.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564037406756,"sku":"3888078","price":235.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/2d9c7e7d-83a8-41bb-bb3e-0a272bfe96e4.png?v=1788652816","url":"https:\/\/marisolmarine.com\/products\/volvo-895","provider":"Marisol Marine Company","version":"1.0","type":"link"}
