The Multiquip 1624121330 Piston Pin Circlip is a genuine OEM component designed for DLW400ES, DLW400ESA, and DLW400ESA1 series diesel light welders. As a factory-sourced replacement, this circlip meets the original engineering specifications set for these machines, ensuring correct retention of the piston pin within the engine assembly. DHS Equipment supplies this part direct, so you can order with confidence knowing you are receiving the exact component your machine calls for.

Key Features

  • Genuine OEM Retention Spec — Manufactured to the original dimensional tolerance that keeps the piston pin securely seated under the cyclical loading of engine operation.
  • Drop-In Engine Compatibility — Engineered to seat directly into the piston pin bore groove without reworking or adjustment, maintaining correct pin alignment on installation.
  • Confirmed Fitment — Verified for DLW400ES, DLW400ESA, and DLW400ESA1 diesel light welder models; cross-reference part number 1624121330 before ordering.
  • Protects Piston and Cylinder Integrity — A failed or displaced circlip allows the piston pin to migrate laterally, causing rapid scoring of the cylinder wall and catastrophic engine damage; replacing this part at first sign of wear prevents far costlier repairs.
  • Built for Engine Rebuild and Overhaul Work — Commonly replaced during piston, ring, or rod service intervals, making this a practical addition to any diesel engine rebuild kit for the DLW400ES series.

A piston pin circlip is a small retaining ring seated in a groove at each end of the piston pin bore. Its job is to prevent the piston pin from walking sideways inside the piston during engine operation. Without it, the pin can contact and score the cylinder liner, leading to loss of compression, increased oil consumption, and ultimately engine failure. During any piston or connecting rod service on the DLW400ES, replacing this circlip is a standard step that costs little but protects the entire bottom-end assembly.
