This product is commonly searched as 105-1645, 1051645, and hydraulic pump 466B. Because Cat model and part-number listings can vary by region, serial number, and machine configuration, please confirm your old pump number, machine model, mounting points, ports, and shaft/spline details before ordering.

Important fitment note: online parts data for 105-1645 commonly shows Cat 446B, while your product name uses 466B. If your machine plate or old pump confirms 466B, keep this listing as 466B. If the machine is actually 446B, update the title and fitment text before publishing.
