The Multiquip 13011ZK7V01 Piston Ring Set OS 0.25 Optional is a genuine OEM oversized piston ring set designed for CA-4-4H and CA4HM walk-behind power trowels. As a direct Multiquip OEM component, 13011ZK7V01 is manufactured to the same specifications as the original part, making it the correct choice for engine rebuilds requiring a 0.25mm oversize bore. This ring set is compatible with CA-4-4H and CA4HM series trowels, giving contractors a dependable path to restoring engine compression during a top-end overhaul.
Key Features
- Genuine OEM Oversize Specification: — Manufactured to exact 0.25mm oversize tolerances, ensuring correct ring-to-bore clearance after a cylinder honing or boring operation.
- Engine Rebuild Ready: — Supplied as a complete ring set for one piston, simplifying parts sourcing during a top-end engine rebuild or overhaul.
- Confirmed Trowel Fitment: — Directly fits CA-4-4H and CA4HM walk-behind power trowels; verify bore has been machined to the 0.25mm oversize specification before installation.
- Compression Restoration: — Correctly sized rings restore cylinder sealing, recover lost compression, and return the engine to full power output after wear or scoring.
- Optional Oversize Designation: — The OS 0.25 designation identifies this as a service-size component intended for cylinders that have been re-bored beyond the standard bore dimension.
Piston rings seal the combustion chamber between the piston and the cylinder wall, controlling compression pressure and regulating oil consumption. Over time, rings wear or lose tension, causing lost compression, increased oil burn, and reduced engine power — symptoms that are often the trigger for a top-end rebuild. An oversize ring set like the 13011ZK7V01 is used when the cylinder bore has been machined to remove scoring or wear, restoring the correct fit between the piston assembly and the freshly bored cylinder wall and returning the engine to proper operating condition.
