Sold as a Nozzle As-Unit Injector, it meters fuel to each cylinder and atomizes it into a fine spray for efficient combustion. This nozzle is commonly cross‑referenced with CAT service numbers such as 8M1584, 8N4697, and 9F0160, and is listed as compatible with Caterpillar engines in aftermarket catalogs that target models like the 3304 and 3306. Constructed to endure the demanding pressures of diesel injection, the 5M4086 integrates into the injector assembly where it works with the pump and control timing to deliver the correct fuel quantity per cycle. When replacing or refurbishing CAT fuel systems on older industrial equipment, the 5M4086 is presented as a replacement option within the CAT parts ecosystem and its cross‑references help ensure compatibility across legacy equipment. Installation typically requires adherence to CAT service procedures, including correct seating of the nozzle to prevent leaks and ensure proper spray characteristics.\u003c\/p\u003e\u003c\/div\u003e","brand":"CATERPILLAR","offers":[{"title":"New","offer_id":51677846864174,"sku":null,"price":73.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_35a9af9b-6137-4229-89fc-5f5404055721.jpg?v=1769568334","url":"https:\/\/plgautomation.com\/products\/caterpillar-inc-5m4086-fuel-injection-nozzles","provider":"PLG Automation ","version":"1.0","type":"link"}
