Fabco 237-D427-001 cage and seal assembly, written 237D427001 without the separators, comes as an assembly rather than as a loose cage and a separate seal. The manufacturer abbreviates it to cage and seal assy in its own listings. Note the letter block in the middle of the number, D427, because that letter is the first thing lost when a number gets copied by hand off a worn tag. Unit pack is one and the UPC is 193174444036. Pro Gear and Transmission sells it as a Meritor Genuine Fabco part and can confirm the number with you over the phone.
