The sun gear sits at the center of the planetary gear set and transmits rotational power from the travel motor through the planetary carrier to drive the tracks. Worn or chipped sun gear teeth cause reduced travel speed, uneven track movement, and accelerated wear on mating planet gears -- replacing this gear restores proper power distribution through the final drive.\u003c\/p\u003e\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTeeth: 18 (sun gear) x 37 (total gear profile per Cat OEM data)\u003c\/li\u003e\n\u003cli\u003eLocation: Final drive planetary gear set\u003c\/li\u003e\n\u003cli\u003eQty: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatible Models\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eCaterpillar:\u003c\/strong\u003e Verify fitment against your machine model and serial number before ordering -- final drive components can vary within the same model line depending on production date and build configuration.\u003c\/p\u003e\u003ch4\u003eReplaces Part Number(s):\u003c\/h4\u003e\u003cp\u003e1191097, 119-1097\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":42453949382739,"sku":"1191097","price":404.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0079\/4060\/3955\/files\/1191097_01.jpg?v=1757953956","url":"https:\/\/www.reliableaftermarketparts.ca\/products\/1191097-gear-sun-18t-fits-caterpillar-models","provider":"Reliable Aftermarket Parts, Inc®","version":"1.0","type":"link"}
