Multiquip 13102 Piston (0.25)

The Multiquip 13102 Piston (0.25) is a genuine OEM oversized service piston designed for a wide range of Multiquip and Whiteman equipment, including plate compactor models MVH158GH, MVC82VHW, MVC64VHW, and MVH408GH, roller models AR13H, AR13HC, and MRH800GS, and an extensive range of masonry saws, mixers, generators, pumps, walk-behind trowels, and welders across the Multiquip portfolio. As a direct OEM component, part 13102 is manufactured to the same specification as the original part, ensuring accurate fit within the engine assembly. The 0.25 oversize designation indicates this piston is sized for engines that have been bored out by 0.25mm over standard, making it the correct service replacement following a cylinder hone or bore. Confirm your engine's bore size before ordering to ensure the right piston size for your application.

Key Features

• Oversize OEM Specification — Manufactured to the 0.25mm over-bore dimension required after cylinder reconditioning, maintaining correct compression and ring seal geometry for the engine.
• Genuine Multiquip OEM Component — Sourced directly from Multiquip, part 13102 meets the original engineering tolerances for piston-to-wall clearance, pin bore alignment, and ring groove dimensions.
• Broad Cross-Equipment Fitment — Compatible with plate compactors (MVH and MVC series), asphalt rollers (AR13H, AR13HC, AR13HA/HAR), Whiteman and Essick mixers, masonry saws (MP and SP series), generators, pumps, trowels, and welders across the Multiquip lineup.
• Engine Integrity Restored — A correctly sized oversize piston restores compression to specification, preventing blow-by, oil consumption, and power loss that result from a worn or undersized piston in a bored cylinder.
• Fuel System and Combustion Safety — Proper piston fit is critical to maintaining combustion chamber sealing; using the correct oversize piston eliminates the risk of combustion gas leakage past the rings, protecting the engine and operator.

A piston is the reciprocating component inside the engine cylinder that converts combustion pressure into mechanical force, driving the crankshaft and ultimately powering the machine. When an engine cylinder is worn or damaged, it is typically bored out to a precise oversize dimension to restore a smooth, true surface — at which point a standard-sized piston will no longer seal correctly. The 0.25 oversize piston fills that bored cylinder accurately, restoring the correct compression ratio and ring seal. Without the right oversize piston, the engine will suffer from low compression, excessive oil burning, hard starting, and reduced output power.
