The Multiquip 8972326030 is a genuine OEM Piston O/S=0.25 DCA25USI 4LE2 designed for the DCA25USI ultra-silent diesel generator. As a factory-sourced oversized piston at a 0.25mm oversize specification, this component is built to restore proper cylinder-to-piston clearance during engine rebuilds on the Isuzu 4LE2 powerplant found in the DCA25USI. Choosing the correct oversize piston is critical to achieving proper compression and long-term engine health, and this genuine Multiquip part ensures the fit and spec match what the engine was engineered to accept.
Key Features
- OEM-Matched Oversize Specification — Manufactured to the exact 0.25mm oversize dimension required for the Isuzu 4LE2 engine, ensuring correct ring land geometry and skirt clearance during an oversize bore rebuild.
- Direct Engine Rebuild Fit — Engineered as a drop-in replacement for the 4LE2 cylinder bore, working with the existing oversize ring and pin components to streamline reassembly.
- Confirmed Fitment for DCA25USI — Specifically validated for the Multiquip DCA25USI ultra-silent generator series, so you can order with confidence against your machine's model code.
- Compression Integrity Restored — A properly sized piston maintains the combustion seal needed for consistent power output; an undersized or worn piston causes blow-by, oil consumption, and loss of generating capacity.
- Genuine Multiquip OEM Part — Sourced directly through Multiquip's authorized parts network, carrying the same material and dimensional standards as the original production component.
A piston is the reciprocating component inside the engine cylinder that converts combustion pressure into mechanical force, driving the crankshaft to generate power. During a cylinder overhaul, when the bore is machined to an oversize diameter to correct wear, a standard-dimension piston will no longer seal correctly — an oversize piston at the matching specification is required to restore proper compression and oil control. When this component is worn or incorrectly sized, the result is reduced engine compression, excessive oil burning, rough operation, and ultimately an inability to sustain rated generator output.
