As a factory-sourced component, this 0.50 mm oversize set is the correct specification for engines that have been bored or honed beyond the standard piston dimension. Sourced directly through Multiquip's OEM supply chain, part 13012ZE2013 delivers the exact fit and material grade your engine rebuild demands across mixer, roller, pump, and generator applications.
Key Features
- OEM Ring Material and Sizing: — Manufactured to the original engine specification with a 0.50 mm oversize tolerance, ensuring correct ring-to-bore contact pressure after a bore or hone.
- Drop-In Oversize Replacement: — Engineered to install in a standard rebored cylinder without additional machining beyond the intended 0.50 mm oversize bore dimension.
- Broad Multiquip Fitment: — Confirmed for MC94P/S, MC94SK, MC94PK, MC64P/S, WM70S/P, R2000H, QP3TH, GA3.6HA, and GA3.6HZ equipment families.
- Restored Compression and Combustion Sealing: — Correctly sized rings restore full compression sealing, preventing blow-by that causes power loss, oil consumption, and hard starting.
- Genuine OEM Part: — Supplied as an authentic Multiquip component, ensuring the ring profile, end gap, and coating match the original engine design for a lasting engine rebuild.
Piston rings seal the combustion chamber between the piston and the cylinder wall, maintaining compression while controlling oil consumption. Over time, rings wear, lose tension, or become damaged, allowing combustion gases to pass into the crankcase — a condition known as blow-by — which causes a loss of power, increased oil burning, and difficulty starting. This 0.50 mm oversize set is intended for use during an engine rebuild when the cylinder bore has been machined beyond the standard diameter; fitting rings of the correct oversize restores the proper sealing contact between the piston and the freshly bored cylinder wall, returning the engine to full operating performance.
