The Multiquip 13012ZF1023 is a genuine OEM Piston Ring Set OS 0.50 Optional designed for a wide range of Multiquip-family equipment including Whiteman mixer models WM70S and WM70P, plate compactor MVC90H, centrifugal pump QP205SH, masonry saw models MP1455HP, MP120E, MP115E, and MP1H, and gasoline generator GAC2.2HZ. As a direct Multiquip OEM part, the 13012ZF1023 is manufactured to the same specifications as the original component installed at the factory. This 0.50mm oversized ring set is intended for engines that have been bored out during a rebuild, ensuring the proper compression seal is restored after cylinder reconditioning.
Key Features
- Genuine OEM Compression Integrity — Manufactured to original Multiquip specifications, this ring set delivers the correct ring gap, tension, and profile for proper cylinder sealing across all compatible engines.
- 0.50mm Oversized Fitment — Sized at OS 0.50 for use in cylinders bored 0.50mm over standard dimensions, making this the correct choice following a professional engine bore and hone.
- Broad Equipment Compatibility — Fits engines across multiple Multiquip product families including WM70S/P mortar mixers, MVC90H plate compactor, QP205SH centrifugal pump, MP-series masonry saws, and GAC2.2HZ generators.
- Restores Full Engine Compression — Worn or broken piston rings allow combustion gases to bypass the piston, causing power loss, excessive oil consumption, and hard starting — a correctly fitted ring set from part 13012ZF1023 brings compression back to operating spec.
- Fuel System Safety Relevance — Proper ring seal prevents crankcase contamination from blow-by gases, protecting the lubrication system and reducing the risk of oil fouling and premature engine failure.
Piston rings form a dynamic seal between the piston and the cylinder wall, serving three critical functions: containing combustion pressure above the piston, controlling oil film on the cylinder wall, and transferring heat from the piston into the cylinder block. When rings wear, lose tension, or break, combustion gases leak past the piston — a condition known as blow-by — which robs the engine of power, increases fuel consumption, and causes oil to burn off in the combustion chamber. The 13012ZF1023 oversized ring set is used during engine rebuilds when the cylinder bore has been machined 0.50mm over its original diameter, restoring the tight clearance needed for efficient combustion and long engine service life.
