New replacement assemblies can be costly, and the availability of quality aftermarket assembly component parts are limited. Planetary assembly wear is generally caused by insufficient lube oil and\/or excessive clearances. Lack of lube causes excessive heat in the pinion gear area and causes the roller bearings to gaul the gear bores and pinion pins. If there is excessive thrust washer wear or endplay, the roller bearings can run without fully contacting the gear bore, causing premature failure of the assembly.\u003c\/p\u003e\n\n\u003cp\u003eSonnax rear planetary rebuild kit 77731-RK includes all parts needed for a complete four-pinion planetary rebuild, with individual components also sold separately.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eHelical pinion gear crafted from case-hardened alloy steel\u003c\/li\u003e\n\u003cli\u003ePinion needle rollers are specifically toleranced for use with matching pins and gears\u003c\/li\u003e\n\u003cli\u003eThrough-hardened steel round washers help eliminate needle roller thrust wear\u003c\/li\u003e\n\u003cli\u003ePinion pins feature lube holes to reduce planetary burn-up\u003c\/li\u003e\n\u003cli\u003eSolid bronze batwing washers eliminate spin and protect against rapid wear.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c\/div\u003e\n\u003cdiv class=\"part-accordion cb spaced-vertical\"\u003e\n\u003cp\u003e\u003cstrong\u003e\u003clabel for=\"components-panel\"\u003eContents:\u003c\/label\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"accordion-content\"\u003e\n\u003cul\u003e\n\u003cli\u003ePinion Gears (4) \u003cem\u003eHelical\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003ePinion Pins (4)\u003c\/li\u003e\n\u003cli\u003ePinion Needle Rollers (80)\u003c\/li\u003e\n\u003cli\u003eRound Washers (8)\u003c\/li\u003e\n\u003cli\u003eBatwing Washers (8)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"col-4\"\u003e\n\u003cp\u003e\u003cstrong\u003eSymptoms:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePlanetary failure\u003c\/li\u003e\n\u003cli\u003ePlanetary wear\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c\/div\u003e\n\u003cdiv class=\"col-4\"\u003e\n\u003cp\u003e\u003cstrong\u003eCause:\u003c\/strong\u003e\u003c\/p\u003e\nInsufficient lube oil and\/or excessive clearances.\u003c\/div\u003e\n\u003cdiv class=\"col-4\"\u003e \u003c\/div\u003e\n\u003cdiv class=\"col-4 last\"\u003e\n\u003cp\u003e\u003cstrong\u003eCorrection:\u003c\/strong\u003e\u003c\/p\u003e\nThis kit offers replacement parts for rebuilding damaged rear planet assemblies and gives rebuilders the option of replacing only the worn components.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e \u003c!-- suncoast-documents:start --\u003e\u003cdiv class=\"suncoast-product-documents\"\u003e\n\u003ch3 class=\"h6\"\u003eDocuments\u003c\/h3\u003e\n\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0832\/4173\/0267\/files\/184140.pdf?v=1793635174\" target=\"_blank\" rel=\"noopener\"\u003eInstructions\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/div\u003e\u003c!-- suncoast-documents:end --\u003e","brand":"Sonnax","offers":[{"title":"Default Title","offer_id":49129565225179,"sku":"77731-RK","price":254.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/4173\/0267\/files\/F198655739.jpg?v=1786546996","url":"https:\/\/suncoastperformance.com\/products\/planetary-rebuild-kit","provider":"SunCoast Diesel","version":"1.0","type":"link"}
