The Multiquip 13011ZH8941 is a genuine OEM Piston Ring Set OS 0.25 Optional designed for a wide range of Multiquip and Whiteman equipment including WM70 mortar mixers, MVC90H plate compactors, MC64 concrete mixers, and QP205SH centrifugal pumps. As an oversized ring set at the 0.25mm oversize specification, this kit is engineered to restore proper cylinder sealing in engines that have been bored out during a rebuild. Sourced directly from Multiquip, part number 13011ZH8941 ensures you receive the correct ring profile, tension, and material grade matched to the original engine design. Confirm your engine's bore size before ordering to ensure this OS 0.25 set is the correct fit for your application.
Key Features
- Oversized Rebuild Specification: — Cut to OS 0.25mm oversize to match bored-out cylinders, restoring correct ring-to-wall clearance after engine reconditioning.
- Genuine OEM Construction: — Manufactured to Multiquip's original ring tension and material tolerances, ensuring proper compression sealing and oil control from the first start-up after rebuild.
- Broad Equipment Compatibility: — Fits engines used across WM70 mortar mixers, MVC90H plate compactors, MC64 mixers, QP205SH centrifugal pumps, and additional Multiquip equipment families.
- Full Ring Set Included: — Supplies the complete set of piston rings needed for one piston, covering compression and oil control rings in a single part number for a straightforward engine rebuild.
- Engine Longevity After Overhaul: — Correctly fitted oversize rings eliminate blow-by, restore power output, and prevent oil consumption issues that result from worn or incorrectly sized rings.
Piston rings seal the combustion chamber between the piston and cylinder wall, maintaining compression pressure and preventing oil from entering the combustion area. When rings wear, lose tension, or are replaced during a cylinder bore job, the engine loses compression, burns oil, and produces less power. An oversized ring set like the 13011ZH8941 is specifically intended for engines where the cylinder bore has been machined to a larger diameter — using the correct OS specification ensures the rings seat properly against the fresh bore surface and restore the engine to full operating condition.
