Multiquip 5351431 Piston Ring Set RW1403F/FMR43F

The Multiquip 5351431 is a genuine OEM Piston Ring Set RW1403F/FMR43F designed for Multiquip roller equipment. As a direct OEM replacement, this ring set is manufactured to the exact tolerances required for proper piston-to-cylinder sealing, ensuring the engine performs as intended. Sourced directly through authorized Multiquip supply channels, the 5351431 is the correct part for maintaining your roller's engine integrity. Confirm your model against the fitment data before ordering to ensure compatibility with your specific unit.

Key Features

• OEM-Spec Ring Tolerancing — Manufactured to exact piston diameter and compression height specifications, ensuring proper sealing contact against the cylinder wall.
• Direct Engine Drop-In — Designed to seat into the piston ring grooves without machining or re-boring, provided the cylinder is within serviceable wear limits.
• Genuine Multiquip OEM Part — Supplied as an authorized OEM component under part number 5351431, sourced through the official Multiquip parts network.
• Restores Compression and Oil Control — Worn or broken piston rings cause blow-by, oil burning, and power loss; replacing with a correctly sized ring set restores engine compression and sealing performance.
• Engine Longevity — A properly seated ring set minimizes combustion gas leakage into the crankcase, protecting bearings and internal engine components from accelerated wear.

Piston rings form the dynamic seal between the piston and the cylinder wall, controlling combustion pressure above the piston and regulating oil film on the cylinder surface below. There are typically multiple rings per piston — compression rings that contain combustion gases and oil control rings that prevent excess oil from entering the combustion chamber. When piston rings wear, crack, or lose tension, the engine suffers reduced compression, increased oil consumption, rough running, and eventual loss of power. Replacing a worn ring set with a correctly specified OEM set like the Multiquip 5351431 restores the engine's compression and extends its service life.
