The Multiquip 71425022551 is a genuine OEM Piston Ring Set O.S=0.50 L40ADRM MT76D designed for the MT-76D rammer. As a direct OEM replacement sourced through Multiquip's authorized parts network, this ring set is manufactured to the exact oversize specification required for a correctly rebuilt MT-76D engine. Confirm your engine's bore condition and oversize requirement before ordering — the 0.50mm oversize designation means this set is intended for use following a matching overbore of the cylinder. DHS Equipment stocks genuine Multiquip OEM parts so you get the right component the first time.
Key Features
- Exact Oversize Specification — Sized at O.S=0.50 to match a correctly bored cylinder, ensuring proper ring-to-wall clearance and compression seal on the MT-76D engine.
- Genuine OEM Construction — Manufactured to Multiquip's material and dimensional standards for the L40ADRM engine, delivering consistent ring tension and sealing across the full compression and oil control rings.
- Direct MT-76D Fitment — Engineered specifically for the MT-76D rammer; no adaptation or guesswork when completing an engine rebuild on this machine.
- Restored Compression and Power — Worn or broken piston rings allow combustion gases to bypass the piston, robbing the rammer of impact energy. A fresh ring set restores proper compression and full tamping performance.
- Reduced Oil Consumption — Failed oil control rings cause the engine to burn oil and foul the combustion chamber. This replacement set reseals the oil film correctly, protecting the cylinder wall and extending engine life after rebuild.
Piston rings form a dynamic seal between the piston and the cylinder wall inside a two- or four-stroke engine. They serve two critical functions: holding combustion pressure above the piston so the engine generates full power, and scraping excess oil from the cylinder wall to prevent it from entering the combustion chamber. When rings wear, break, or lose tension, compression drops, oil consumption rises, and the engine produces noticeably less force — on a rammer like the MT-76D, that translates directly to reduced impact energy and poor compaction results. Replacing the ring set with a correctly sized oversize set during an engine rebuild restores the tight fit between piston and bore that proper performance depends on.
