The Multiquip 26823403H3 Piston Oversize 0.5 is a genuine OEM component designed for MTX80 and MTX90 series rammers. As a factory-sourced oversize piston, 26823403H3 is dimensioned 0.5mm over the standard bore specification, making it the correct choice when re-boring a worn cylinder during engine rebuild. This part ships directly from Multiquip's authorized supply chain, ensuring you receive an exact-match component engineered to the same tolerances as the original.
Key Features
- OEM Bore Tolerance: Machined to Multiquip's oversize 0.5 specification, ensuring proper piston-to-wall clearance after cylinder re-boring for correct compression and ring seal.
- Drop-In Rebuild Fit: Sized and profiled to install directly into a re-bored MTX80 or MTX90 cylinder without secondary machining beyond the standard overbore procedure.
- Rammer Family Compatibility: Confirmed fitment for MTX80 and MTX90 tamper models — consult your service manual to verify bore size before ordering.
- Restores Full Compression: A correctly fitted oversize piston re-establishes the compression necessary for strong, consistent ram stroke — a worn or undersized piston causes misfires, weak impact force, and hard starting.
- Engine Rebuild Confidence: Using the correct OEM oversize piston during a top-end rebuild protects the investment in cylinder re-boring work and extends the service interval before the next overhaul.
The piston is the reciprocating component inside the engine cylinder that converts combustion pressure into mechanical force — in a rammer, that force drives the foot plate downward to compact soil and aggregate. Over time, piston-to-cylinder wall clearance increases due to wear, reducing compression and weakening impact energy. When a cylinder is re-bored to restore its geometry, a standard-size piston is no longer the right fit; an oversize piston — such as this 0.5 oversize — is required to fill the enlarged bore correctly, re-seal combustion gases, and bring the engine back to its original operating performance.
