LINER O-RING KIT

This is a cylinder liner O-ring kit for Caterpillar 3406E, C15, C16, and C18 diesel engines with crevice seal liners. It seals the cylinder liner to the engine block to prevent coolant and oil leaks. The kit is typically replaced during an engine overhaul or when liner seals fail. It includes the necessary O-rings and seal rings for one cylinder liner.
