The Multiquip 13103ZF6W00 is a genuine OEM Piston Optional OS 0.50 designed for a wide range of Multiquip-family equipment including Essick Mixers (EM120P Series, EM120S Series), Whiteman Mixers (WM120PH, WM120SH), Rollers (MRH800GS), and Saws (SP118, SP1CE13H18). As a factory-sourced component, this oversize piston is engineered to the exact tolerances required for proper engine rebuilding and long-term performance. Sourced directly through authorized Multiquip channels, this is the correct part for engines requiring a 0.50mm oversize bore specification. DHS Equipment stocks genuine Multiquip OEM parts to help you get the right component the first time.
Key Features
- Oversize Bore Precision: — Manufactured to an OS 0.50 specification, ensuring correct piston-to-cylinder wall clearance after a 0.50mm overbore engine rebuild.
- Genuine OEM Construction: — Cast and finished to Multiquip's original engine specifications, maintaining the compression ratio and thermal characteristics of the original powerplant.
- Broad Cross-Equipment Fitment: — Compatible with EM120P Series, EM120S Series, WM120PH, WM120SH, MRH800GS, SP118, and SP1CE13H18 equipment families.
- Engine Rebuild Essential: — A correctly sized oversize piston restores proper compression and combustion efficiency; an undersized or wrong-spec piston leads to blow-by, oil consumption, and premature failure.
- Direct OEM Replacement: — Drops into the cylinder bore following a standard 0.50mm overbore hone, with ring grooves, pin bore, and crown profile matched to the original engine design.
The piston is the reciprocating heart of a four-stroke engine — it converts combustion pressure into crankshaft rotation and also helps seal the combustion chamber from the crankcase. Over time, cylinder walls and piston skirts wear, allowing gases to bypass the rings and reducing compression. When an engine is bored out to restore the cylinder wall surface, an oversize piston like the OS 0.50 is required to fill the enlarged bore correctly, re-establishing the compression seal and restoring full engine output. Installing the wrong size piston will result in excessive clearance, weak compression, increased oil consumption, and accelerated wear.
