WESPC CH11654 Cylinder Liner O Ring Seal for Perkins 2806 Series Replacement

Application

WESPC CH11654 is a sealing ring used in the cylinder block assembly of Perkins 1106D-E66TA and 1106D-70TA diesel engines. It provides a secure seal between the cylinder liner and engine block, preventing coolant and combustion gas leakage. This component is critical for maintaining compression integrity and thermal isolation in dry-type liner configurations.

Generator sets

Applied in 200–350 kVA Perkins-powered generator sets equipped with 1106D series engines. The CH11654 seal ensures stable operation under continuous load by maintaining liner-to-block sealing, contributing to fuel efficiency and engine reliability.

Industrial systems

Used in stationary diesel-driven equipment such as water pumps, compressors, and hydraulic systems powered by Perkins 6-cylinder engines. The seal resists thermal expansion and mechanical stress, supporting long-term durability in industrial environments.
