The Multiquip 6162232240 is a genuine OEM O Ring Lower Liner SA6D170A DCA600SPK designed for the DCA600SPK ultra-silent diesel generator. As a direct Multiquip OEM component, this O-ring is manufactured to the exact material and dimensional specifications required by the SA6D170A engine, ensuring a proper seal at the cylinder liner interface. This part is confirmed to fit DCA600SPK series equipment, making it a direct service replacement for scheduled engine maintenance or liner reseal work.

Key Features

  • Genuine OEM Sealing Material — Manufactured to the precise compound hardness and cross-section profile required for the SA6D170A cylinder liner, maintaining correct compression under engine operating temperatures and pressures.
  • Direct Drop-In Replacement — Engineered to seat correctly in the lower liner groove of the SA6D170A engine block, requiring no trimming or reworking during installation.
  • Confirmed Fitment — Compatible with DCA600SPK ultra-silent diesel generator units equipped with the SA6D170A engine.
  • Coolant Leak Prevention — A correctly installed lower liner O-ring prevents coolant from migrating past the liner into the crankcase, protecting engine oil integrity and avoiding catastrophic engine damage.
  • Critical Engine Service Component — Replacing this O-ring during liner removal or engine overhaul is essential to restore a leak-free seal and maintain proper cylinder cooling across the full service life of the engine.

The lower liner O-ring forms a critical coolant seal between the cylinder liner and the engine block on the SA6D170A diesel engine. It prevents engine coolant from bypassing the liner and contaminating the engine oil — a failure that, if left unchecked, leads to rapid bearing wear, overheating, and potential engine seizure. Any time the cylinder liners are disturbed during engine maintenance or overhaul, replacing this O-ring with a genuine part like the Multiquip 6162232240 is standard practice to ensure a reliable, leak-free reassembly.
