A remanufactured pump occupies an awkward position in a parts catalogue. It is neither new nor used, buyers often assume it is one or the other, and the difference in real terms is large enough to be worth spelling out. This page covers the YA00006715 fan pump as we actually supply it, and what the word remanufactured has to cover for the part to be worth buying.<\/p>\n
The photographs on this listing are of the assembly we work from. The Hitachi nameplate reads YA00006715<\/strong>, works number 18315641, Hitachi Construction Machinery Co., Ltd, Made in Japan<\/strong>. The housing carries cast markings including 63F<\/strong> \uff0c K6V63<\/strong> size designation, and the control solenoid with its sticker is present as fitted at the factory.<\/p>\n Those castings settle a question that the trade leaves open. Supplier listings for YA00006715 describe it variously as a gear pump and as a piston pump, and some attach it to ZX470-3 while others attach it to the 670 and 690 class. The physical unit shown here is an axial piston pump of the 63 cm3 size class with an electrically controlled regulator, which is consistent with how Hitachi drove the cooling fan on these machines. If your old pump is an aluminium gear unit, this is not the part you need and we would rather say so now than after it arrives.<\/p>\n The term is used loosely across our industry, so here is the benchmark we work against. Caterpillar, whose Reman programme covers hydraulic pumps and motors among other units, publishes the process: the core is disassembled to its smallest piece parts, cleaned, inspected, with salvage by machining or laser deposition where the housing or shaft allows it, then reassembled to original specification incorporating current engineering updates, and tested to the same standards as a new part before being released with a same-as-new warranty. Cat also publishes that Reman parts typically price at 45 to 85 percent of new against a returned core.<\/p>\n That is a demanding definition, and it is the right one, because a pump that has only had seals replaced will still have scored bores and worn slipper faces, and it will fail in the same way the original did. Our remanufactured fan pumps are built to that scope:<\/p>\nWhat remanufactured has to mean<\/h2>\n
