The Multiquip 5122110180 is a genuine OEM Piston Pin DCA25USI 4LE2 designed for Multiquip Diesel Powered Generators. Sourced directly from Multiquip, this part carries the exact specifications required by the 4LE2 engine to maintain proper piston-to-rod alignment and compression integrity. It is confirmed for use with the DCA25USI ultra-silent diesel generator series. When you need a part you can trust to spec, the OEM designation means there is no guesswork on fit or material grade.
Key Features
- OEM-Grade Material Hardness — Manufactured to the precise hardness and surface finish specifications the 4LE2 engine demands, ensuring the pin handles the cyclic load of combustion without premature wear.
- Drop-In Engine Compatibility — Dimensioned to the exact bore and rod tolerances of the 4LE2 powerplant, so installation follows the standard engine rebuild procedure without reworking bores or bushings.
- Confirmed Fitment for DCA25USI — Verified for Multiquip DCA25USI ultra-silent diesel generator units powered by the 4LE2 engine.
- Compression and Power Output Protection — A correctly fitted piston pin keeps the piston centered and stable through every combustion cycle, preserving rated generator output and preventing erratic engine behavior caused by pin slap or lateral piston movement.
- Engine Safety Compliance — Using the correct OEM pin prevents the risk of catastrophic engine failure that can result from an undersized or incorrect-alloy pin under sustained generator load.
The piston pin — sometimes called a wrist pin — connects the piston to the connecting rod inside the engine cylinder, transferring the force of combustion downward into the crankshaft to generate power. It must withstand intense, repeated mechanical stress with every engine cycle, so the material grade and dimensional accuracy of this component are critical. When a piston pin wears, becomes loose, or fails, it produces a characteristic knocking noise, causes loss of compression, and can lead to severe internal engine damage if not addressed promptly.
