The swing drive gearbox rotates the upper structure of the excavator on the undercarriage chassis. Three planetary shafts are used per swing drive assembly, working in conjunction with the planetary gears, sun gears, carrier, and ring gear to transfer torque from the swing motor to the slewing ring. Replacing worn or damaged planetary shafts restores proper gear mesh, prevents further damage to the carrier and housing, and returns smooth, controlled swing operation.\u003c\/p\u003e\u003ch4\u003eCompatible Models\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eCaterpillar Excavators:\u003c\/strong\u003e 318C, 318E L, 319C, 319D, 319D L, 319D LN, 320C, 320C FM, 320C L, 320D, 320D FM, 320D FM RR, 320D GC, 320D L, 320D LN, 320D LRR, 320D RR, 320D2, 320D2 GC, 320D2 L, 320E, 320E L, 320E LN, 320E LRR, 320E RR, 321C, 321D LCR, 323D L, 323D LN, 323D SA, 323D2 L, 323E L\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCaterpillar Mobile Hydraulic Power Units:\u003c\/strong\u003e 323D L, 323D LN\u003c\/p\u003e\u003ch4\u003eReplaces Part Number(s):\u003c\/h4\u003e\u003cp\u003e1484634, 148-4634\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":42452444414035,"sku":"1484634","price":81.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0079\/4060\/3955\/files\/1484634_01.jpg?v=1757807950","url":"https:\/\/www.reliableaftermarketparts.ca\/products\/1484634-shaft-planetary-fits-caterpillar-models","provider":"Reliable Aftermarket Parts, Inc®","version":"1.0","type":"link"}
