Multiquip 13011ZK7V01 Piston Ring Set OS 0.25 Optional

The Multiquip 13011ZK7V01 is a genuine OEM Piston Ring Set OS 0.25 Optional designed for a range of Multiquip plate compactors, centrifugal pumps, and walk-behind power trowels including MVC-64H, MVC-64HW, MVH-R60H, MVH-R60W, QP2H, QP-204H, CP-20H, CA4HM, CA4HC, CA4.4HM, and CA-4-4H models. As a genuine OEM component sourced directly through Multiquip, part 13011ZK7V01 delivers the exact dimensional tolerances required for an oversized engine rebuild. This 0.25 mm oversize ring set is the correct service solution when cylinder bores have been honed to the first oversize specification, restoring proper compression and oil control to your engine.

Key Features

• Genuine OEM Ring Geometry — Manufactured to exact oversize tolerances, ensuring correct ring end gap, radial depth, and axial height for a proper engine rebuild at the OS 0.25 specification.
• Oversize Rebuild Application — Engineered specifically for engines where the cylinder bore has been honed to the 0.25 mm oversize dimension, dropping in without additional machining at that service stage.
• Broad Cross-Equipment Fitment — Compatible with MVC-64H, MVC-64HW, MVH-R60H, MVH-R60W, QP2H, QP-204H, CP-20H, CA4HM, CA4HC, CA4.4HM, and CA-4-4H, covering plate compactors, centrifugal pumps, and walk-behind trowels that share the same engine platform.
• Compression and Oil Control Restored — A correctly fitted ring set re-establishes the combustion seal and oil film regulation that a worn or scored ring set can no longer maintain, returning the engine to full operating power.
• Fuel System and Emissions Integrity — Proper ring sealing prevents blow-by that can contaminate the crankcase, cause excessive oil consumption, and push fuel efficiency out of acceptable operating range.

Piston rings seal the combustion chamber between the piston and the cylinder wall, allowing the engine to build and hold compression while also controlling how much oil reaches the combustion area. When rings wear, lose tension, or become damaged, the engine loses compression pressure, consumes excess oil, produces blue smoke, and delivers noticeably reduced power output. An oversize ring set like the part is used during an engine overhaul after the cylinder bore has been bored or honed to a larger diameter — in this case 0.25 mm over standard — so the new rings correctly fill the enlarged bore and restore the original tight seal between piston and cylinder wall.
