Find a service part or donor lead

Have an MX-5050 that needs a part, but can't find another of your model to use as a donor? Search by your machine, the part number, or the part name.

This cross-reference shows when factory documents list the same or a renumbered part in another model or generation. That gives you another donor machine to look for. Each lead links to its printed source; check the physical fit before buying a donor or fitting the part.

Also search the full site. It searches the text of the digital editions held here, so you may find a part mentioned in a manual even when this cross-reference has no entry.

Enter the full plate designation if you have it. Part numbers accept spacing and punctuation variants; suffix letters matter.

“Same factory number; verify fit” and “Factory renumbering; verify fit” describe document evidence, not guaranteed interchangeability. A missing row means only “Not established in indexed sources.” Service parts are separate from OEM accessories.
