On models such as the RD12A-90, it is located at the exciter and front drum assembly, where the vibratory mechanism generates the 4,200 vpm frequency used to compact soil and asphalt.\u003c\/p\u003e\n\n\u003cp\u003eThe exciter on these Wacker Neuson rollers operates under continuous rotational load and requires precise shaft-to-hub alignment to deliver consistent vibration output. A worn, sheared, or missing Woodruff key in this location can result in loss of vibration, irregular drum behavior, or accelerated bearing wear. Replacing this key during exciter service or anytime the exciter shaft is disassembled restores proper mechanical engagement between components.\u003c\/p\u003e\n\n\u003cp\u003eThe exciter on RD12 and RD12A series machines uses Mobil SHC 220 grease for lubrication, and this key should be inspected whenever the exciter grease fittings are serviced or the drum assembly is opened for maintenance.\u003c\/p\u003e\n\n\u003cp\u003eCompatible with the following Wacker Neuson models:\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eCB14B-1000\u003c\/li\u003e\n\u003cli\u003eCB14B-900\u003c\/li\u003e\n\u003cli\u003eRD11A\u003c\/li\u003e\n\u003cli\u003eRD11AEC\u003c\/li\u003e\n\u003cli\u003eRD11V\u003c\/li\u003e\n\u003cli\u003eRD12-90\u003c\/li\u003e\n\u003cli\u003eRD12A-90\u003c\/li\u003e\n\u003cli\u003eRD12L-90 Fixed ROPS\u003c\/li\u003e\n\u003cli\u003eRD14K-90\u003c\/li\u003e\n\u003cli\u003eRD16-100\u003c\/li\u003e\n\u003cli\u003eRD16-90\u003c\/li\u003e\n\u003cli\u003eRD880V\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGenuine Wacker Neuson OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Wacker Neuson","offers":[{"title":"Default Title","offer_id":43398206095408,"sku":"WACKER-5002009108","price":13.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5002009108.jpg?v=1784052016","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-woodruff-key-5002009108-for-ride-on-rollers","provider":"CCE Industries","version":"1.0","type":"link"}
