Caterpillar cam follower (roller lifter) and side cover assembly, number 7W3871 cast into the aluminum cover along with the CAT logo. The assembly consists of two twin-roller cam follower carriers retained in one painted aluminum engine side cover.

Application: commonly associated with the Caterpillar 3116 / 3126 / C7 engine family. The donor engine model, serial number, and application are NOT documented, so fitment is unverified — this part is sold by photographs, cast identifiers, and dimensions.

Condition: used, untested take-off. Cover paint is chipped with light surface rust and old gasket residue; roller followers are present and appear complete in the photos. No testing, measurement, or crack inspection has been performed and none is implied. No gasket or hardware included — only what is pictured.

Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.

Quote is subject to final fitment confirmation by engine/transmission serial number, part number, photos, and supplier availability.
