Caterpillar 4T-6918 Stem

Caterpillar 4T-6918 Stem is a Caterpillar spare part identified by the catalog number 4T-6918. In some catalogs and aftermarket listings, it is described explicitly as a stem component, and related Cat parts pages show the 4H-6918 code in the same family of small, precision devices (classified there as a shim). This clustering suggests that 4T-6918 belongs to a family of interchangeable, machined components used in Caterpillar equipment. The exact fit depends on the machine model and configuration, as Cat catalogs organize related items by family rather than a single universal description. Suppliers such as AGA Parts list the item under the 4T6918 stem designation, underscoring its availability as a replacement part beyond OEM channels. As with other Caterpillar spares, the 4T-6918 stem is intended to restore original performance by replacing worn or damaged stem components in compatible systems. When sourcing, align the 4T-6918 code with your machine’s service literature or parts diagram to confirm correct replacement, avoiding mix-ups with other similarly numbered components in the same Cat family.
