We publish both numbers on this page and quote against your plate photograph.<\/p>\n<h2>Aplicabilidade e evid\u00eancias<\/h2>\n<p>Komatsu WA380-6 and WA430-6 wheel loaders, listed in trade parts data as the main hydraulic pump. Komatsu&#8217;s own online catalogue returns no page for either number, so the item name is trade-established rather than manufacturer-confirmed, and no displacement, pressure or flow figure is published for it here. The 708-1x prefix is consistent with a pump in Komatsu&#8217;s hydraulic group; the fan pump and the steering pump on the same machine are separate items, listed separately.<\/p>\n<h2>Three pumps, one loader<\/h2>\n<p>On a WA380-6 the hydraulic side is split three ways, and knowing which one is failing is the whole ordering question:<\/p>\n<ul>\n<li><strong>Main pump<\/strong> (this item) drives the boom, bucket and steering priority.

Inspect the oil: glitter means a flush and a filter change, not just a new pump. On fitting, match shaft spline, pilot, flange, port positions and control orientation against the removed unit, prime the casing with clean oil before cranking, keep the case drain unrestricted to tank, change the return filter element, and target ISO 4406 18\/16\/13.
