Multiquip 13012ZF1023 Ring Set Piston (0.50) - OEM Replacement Part

This oversized piston ring set provides critical compression sealing for the Honda GX160 engine used in Multiquip MVC-90H plate compactors. The 0.50mm oversize rings are used during engine rebuilds when cylinders have been bored to restore proper compression and oil control after wear or damage.

The MVC-90H plate compactor utilizes a Honda GX160K1QMX2/GX160U1QMX2 air-cooled, 4-stroke gasoline engine with 9.9 cubic inch (163cc) displacement producing 5 HP at 3,600 RPM. Common symptoms indicating piston ring replacement include loss of compression, excessive oil consumption, blue exhaust smoke, reduced engine power, and difficulty maintaining the 2,300 RPM required to engage the centrifugal clutch. When the throttle is moved to FAST position and the engine cannot achieve proper operating speed, worn piston rings are often the culprit.

This ring set is designed for engines that have been precision-bored 0.50mm oversize as part of a professional rebuild. Proper installation requires cylinder measurement, honing, and adherence to manufacturer specifications for ring end gap and installation procedures.
