The Multiquip 13011Z4K004 is a genuine OEM Piston Ring Set (0.25) designed for a range of Multiquip equipment including GAC2.2HZ generators, SP1G flat saws, and MVC82VH, MVC82VHW, and MVH158GH plate compactors. As a direct OEM replacement, this 0.25mm oversize ring set is sourced from Multiquip's authorized parts supply, ensuring the dimensions and material grade match the original engine specification exactly. Confirm your model code and engine displacement before ordering to ensure this oversize set is the correct fitment for your application.
Key Features
- Genuine OEM Ring Tolerances — Manufactured to the exact radial thickness, gap clearance, and tension spec of the original rings, ensuring proper cylinder wall contact and sealing pressure.
- 0.25mm Oversize Set — Sized for engines that have been bored 0.25mm over standard, making this the correct choice following a cylinder bore or hone during engine rebuild.
- Broad Equipment Compatibility — Fits GAC2.2HZ generators, SP1G saws, and MVC82VH, MVC82VHW, and MVH158GH plate compactors sharing the same engine platform.
- Compression Integrity Restored — A fresh ring set re-establishes the combustion seal between piston and cylinder wall, recovering lost compression and engine output caused by worn or broken rings.
- Fuel System and Emissions Compliance — Properly seated rings prevent oil from entering the combustion chamber, keeping fuel consumption and exhaust emissions within the engine's designed operating range.
Piston rings seal the gap between the piston and the cylinder wall, maintaining combustion pressure, controlling oil consumption, and transferring heat from the piston into the cylinder bore. There are typically three rings per piston: compression rings that hold combustion gases above the piston, and an oil control ring that scrapes excess oil back down into the crankcase. When rings wear, lose tension, or break, the engine loses compression, burns oil, produces blue or white smoke, and delivers noticeably less power — eventually making the machine unreliable or impossible to start. Replacing the ring set during an engine rebuild with the correct oversize specification restores the engine's ability to generate and hold compression through each combustion cycle.
