The 0.82mm thickness designates this as an oversized head gasket, used when the engine block deck has been machined and the standard-thickness gasket is no longer appropriate.\u003c\/p\u003e\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003cul\u003e  \u003cli\u003eThickness: 0.82mm (oversized\/thicker-than-standard)\u003c\/li\u003e  \u003cli\u003eType: Cylinder Head Gasket\u003c\/li\u003e  \u003cli\u003eApplication: Caterpillar diesel engines (see note below)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatible Models\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e This gasket is identified as a 0.82mm thick (oversized) cylinder head gasket for Caterpillar engines. Oversized head gaskets are used on the Cat 3114, 3116, and 3126 (2-valve) engine families when deck surface machining has reduced the block deck-to-crankshaft centerline measurement below standard specification. Always verify your engine serial number and block deck measurement before ordering to confirm this is the correct thickness for your application.\u003c\/p\u003e\u003ch4\u003eReplaces Part Number(s):\u003c\/h4\u003e\u003cp\u003e1258842, 125-8842\u003c\/p\u003e\u003cp\u003eNew aftermarket replacement part - not remanufactured, not used.\u003c\/p\u003e","brand":"Reliable Aftermarket Parts, Inc® -OD","offers":[{"title":"Default Title","offer_id":42454000566355,"sku":"1258842","price":35.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0079\/4060\/3955\/files\/1258842_01.jpg?v=1757959846","url":"https:\/\/www.reliableaftermarketparts.ca\/products\/1258842-gasket-fits-caterpillar-models","provider":"Reliable Aftermarket Parts, Inc®","version":"1.0","type":"link"}
