Replacing the entire head is a sensible choice when wear affects not only the gears but also the rotating supports and seals: these elements determine alignment, smoothness, and \"quietness\" over time. With a complete assembly, couplings and seats are restored together, reducing the risk of mounting a new gear on already worn bearings or seals, which would lead to vibrations and noise returning quickly. It is also useful when the head has operated with insufficient lubrication or dirt infiltration: in these cases, in addition to gear wear, friction and internal play increase, resulting in less clean cuts and a feeling of irregular dragging. Replacing the complete assembly serves to restart with a more uniform rotation and better sealing of the group.\u003c\/p\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eType: Complete final drive head.\u003c\/li\u003e\n\u003cli\u003eFunction: Transfer of motion from the shaft to the cutting element with direction change.\u003c\/li\u003e\n\u003cli\u003eConfiguration: Complete assembly with internal transmission components, supports, and seals.\u003c\/li\u003e\n\u003cli\u003eTransmission: Drive with bevel gears.\u003c\/li\u003e\n\u003cli\u003eSupport: Rotation system on bearings with spacers and locking rings.\u003c\/li\u003e\n\u003cli\u003eSeal: Seals and retaining components for protection against dust and debris.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKit components:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eComplete head body.\u003c\/li\u003e\n\u003cli\u003eBevel gear.\u003c\/li\u003e\n\u003cli\u003ePinion gear.\u003c\/li\u003e\n\u003cli\u003eBearings.\u003c\/li\u003e\n\u003cli\u003eSeals.\u003c\/li\u003e\n\u003cli\u003eSpacers.\u003c\/li\u003e\n\u003cli\u003eWashers.\u003c\/li\u003e\n\u003cli\u003eLocking rings.\u003c\/li\u003e\n\u003cli\u003eFixing screws.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"viviincampagna","offers":[{"title":"Default Title","offer_id":57114351337797,"sku":"20080674","price":122.45,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/5114\/7333\/files\/coppia-conica-completa-decespugliato.jpg?v=1772013810","url":"https:\/\/www.viviincampagna.com\/en-eu\/products\/complete-conical-couple-brushcutter-echo-srm-520esu-420es-rm-520es","provider":"viviincampagna","version":"1.0","type":"link"}
