A double pump looks like a simple swap and is not. Two sections on one shaft means two circuits, and on these excavators one of them may be doing something other than driving the fan. Order the wrong section count and you either lose pilot pressure or leave a port open to tank.<\/p>\n
Volvo EC330B, EC360B and EC460B excavators, described in dealer parts data as a double gear pump in the oil cooling family, grouped with 14530502, 14561970 and 14561971. Volvo’s own catalogue does not return a citable page for 14525545, so the description is dealer-established. The related EC360 and EC460 fan pump family is covered on our 14530502 page<\/a>, including which numbers are single and which are double.<\/p>\n Wear in a gear pump shows as flow that fades as the oil heats. Test at working temperature, after cleaning the cores, and compare against the machine specification rather than against another machine of the same badge. Prime the replacement with clean oil before cranking, change the return filter element, clear the suction strainer, confirm rotation direction against the old unit, and keep the case drain unrestricted to tank. Target ISO 4406 18\/16\/13 for the piston components sharing the circuit. Our gu\u00eda de diagn\u00f3stico de la bomba del ventilador<\/a> covers the measurement sequence.<\/p>\n Minimum order one piece. Three to six month warranty on new aftermarket units as stated on your proforma invoice; bench checked and photographed against your order before the wooden case closes, delivery 5 to 8 working days from payment subject to stock.
