Part: YA00005829 hydraulic fan motor for Hitachi ZX450-3, ZX470-3, ZX850-3 and ZX870-3 excavators, new Chinese-made replacement, HTD brand.

Why buyers choose this grade: it carries a three to six month warranty, ships in 5 to 8 working days, and is stocked for fleet quantities rather than one-off surplus.

Check first: this is the square-flange unit with the silver cover and bottom work ports. It is not the same physical part as the Parker-built 4634936.
