This one drives the cooling fan. It is smaller than the main pumps, it is cheaper than the main pumps, and it is regularly mis-sold as one of them because a supplier title said so.<\/p>\n<h2>What this pump is<\/h2>\n<p>Dealer parts data describes 14676708 as a fan or cooling drive pump for the EC950 and EC950E, built on a K5V80-class variable displacement axial piston platform. Volvo&#8217;s own online catalogue does not return a citable page for the number, so the type and the size class are dealer-established rather than manufacturer-confirmed.<\/p>\n<p>What we can state clearly is the distinction that matters. The EC950 main hydraulic pump is a much larger K3V280-class unit carrying a different part number and a price several times higher. If a quotation offers you 14676708 as the main pump, or offers a K3V280 as the fan pump, one of them is wrong, and it is usually the quotation.<\/p>\n<h2>Why a cooling pump on a 90 tonne machine is a wear item<\/h2>\n<ul>\n<li>The engine is rated at 450 kW from Volvo&#8217;s D16 in the manufacturer&#8217;s published EC950E specification. Most of that energy eventually leaves the machine as heat, and a large share of it leaves through the cooling pack.<\/li>\n<li>The pump spends long periods at or near maximum displacement, because a quarry machine rarely has idle time in a cool ambient.<\/li>\n<li>Its output feeds a fan motor that also reverses, so the circuit sees direction changes and drain conditions that a single-direction system never meets.<\/li>\n<\/ul>\n<h2>Diagnosereihenfolge<\/h2>\n<ol>\n<li>Reinigen Sie die K\u00fchlerlamellen und messen Sie die K\u00fchlmittel- und Hydraulik\u00f6ltemperatur bei niedriger und hoher Leerlaufdrehzahl unter Last erneut.<\/li>\n<li>Confirm the fan accelerates when demand rises and reverses when commanded.<\/li>\n<li>Measure flow and pressure at the pump outlet at working temperature.<\/li>\n<li>Check the pilot and control signal before condemning the pump; a pump never commanded to full stroke behaves exactly like a worn one.
