Located within the burner cpl. and oil burner cpl. assemblies, the pump drive key maintains the mechanical coupling between the drive shaft and pump, ensuring proper fuel delivery to the burner. Wear, shear, or loss of this key results in the pump spinning freely without engaging, interrupting fuel flow to the burner and preventing the heater from firing.\u003c\/p\u003e\n\n\u003cp\u003eThis part is used across diesel-fired and oil-fired burner configurations on both skid-mounted and mobile indirect air heater platforms. When servicing the oil burner or replacing the fuel pump, inspect the drive key for wear, deformation, or damage and replace as needed to restore proper pump engagement.\u003c\/p\u003e\n\n\u003cp\u003eCompatible with the following Wacker Neuson models:\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eCUB 400\u003c\/li\u003e\n\u003cli\u003eCub 700 \/ Cub 700GM \/ Cub 700M\u003c\/li\u003e\n\u003cli\u003eHI260\u003c\/li\u003e\n\u003cli\u003eHP252\u003c\/li\u003e\n\u003cli\u003eHSH 350 \/ HSH350\u003c\/li\u003e\n\u003cli\u003eHSH 380S \/ HSH380B \/ HSH380S\u003c\/li\u003e\n\u003cli\u003eHSH 650\u003c\/li\u003e\n\u003cli\u003eHSH700G\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":43397403312176,"sku":"WACKER-5000169290","price":38.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5000169290.jpg?v=1784035382","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-drive-key-pump-5000169290-for-hydronic-air-heaters","provider":"CCE Industries","version":"1.0","type":"link"}
