Then it looks like a design decision.<\/p>\n<h2>Why a rigid truck shares a hauler pump<\/h2>\n<p>The T450D and the A-series articulated haulers of the same era draw on the same engine and hydraulic component pool. Pump train, drive coupling and the pressure architecture are shared where the machine duty allows it, so one pump number legitimately serves both a rigid truck and an articulated hauler. That is normal OEM practice, and it is also why a parts list that looks wrong is sometimes the most accurate one in the catalogue.<\/p>\n<h2>Applicability and evidence<\/h2>\n<p>Volvo A35D, A40D and T450D, described in dealer parts data as a main hydraulic pump. Volvo&#8217;s own online catalogue does not return a citable page for 11707966, so the machine list is dealer-established rather than manufacturer-confirmed. No displacement, pressure or flow figure is published for the number, and none is quoted on this page.<\/p>\n<h2>What to check before ordering<\/h2>\n<ul>\n<li>The number cast on your pump housing, including any suffix.<\/li>\n<li>Shaft spline count and length, pilot diameter and flange bolt pattern.<\/li>\n<li>Port positions and the orientation of the control or compensator block.<\/li>\n<li>Machine serial prefix, since the pump train differs between some build ranges within the same model.<\/li>\n<\/ul>\n<p>Send those four and we confirm before invoicing. If the evidence points to a different item, we say so rather than sending a close match.<\/p>\n<h2>Diagnosis and fitting<\/h2>\n<p>On a loaded hauler or truck the pump is judged by cycle time: measure tip and hoist times hot, compare against a known-good machine, then check relief settings and the holding valves before condemning the pump. Match the replacement against the removed unit, prime with clean oil before cranking, change the return filter element, clear the suction strainer, keep the case drain unrestricted to tank, and target ISO 4406 18\/16\/13.
