As an authorized Multiquip OEM part, 6162232220 delivers the exact material grade, compression profile, and dimensional tolerancing required by the SA6D170A engine assembly. This part is confirmed for the DCA600SPK series, ensuring a direct, correct-fit installation without guesswork.

Key Features

• OEM-Grade Sealing Material — Manufactured to Multiquip OEM specification, this o-ring uses the correct elastomer compound to maintain a reliable seal under the thermal and pressure cycles of the SA6D170A engine.
• Direct Center Liner Fit — Dimensioned to seat precisely within the center liner bore of the SA6D170A, ensuring correct compression and sealing contact on installation.
• Confirmed DCA600SPK Fitment — Verified for the DCA600SPK ultra-silent generator series; check your model code before ordering to ensure compatibility.
• Leak Prevention at the Source — A correctly seated center liner o-ring maintains coolant or fluid containment within the engine block; a worn or cracked o-ring can allow fluid migration and lead to overheating or contamination.
• Genuine Multiquip Part — Sourced directly through the Multiquip OEM supply chain, so you receive the same component installed at the factory — not a generic substitute.

An o-ring center liner seals the interface between a cylinder liner and the engine block, preventing coolant from bypassing its intended passages and entering the combustion chamber or oil circuit. In the SA6D170A engine fitted to the DCA600SPK generator, this seal plays a critical role in maintaining proper engine operating temperature and fluid integrity. When this o-ring degrades — through heat cycling, age, or chemical exposure — it can allow coolant leaks that lead to overheating, loss of output power, or internal engine damage if left unaddressed.
