The Multiquip 1612350207 Ring Set 0.25mm EC12D MT85EC12D is a genuine OEM piston ring set designed for MT85 series rammers. Sourced directly through the Multiquip OEM parts program, this ring set is built to the same specifications as the original components installed at the factory. Correct fitment is confirmed for the MT85 rammer family, making it a direct, drop-in service part for engine rebuilds on these machines. When your MT85 is showing signs of worn rings — such as loss of power, excessive oil consumption, or hard starting — this is the part that restores it to proper working order.
Key Features
- OEM-Matched Compression Tolerances — Engineered to the same ring gap and tension specs as the original equipment, ensuring proper cylinder sealing and combustion efficiency in the EC12D engine.
- 0.25mm Oversize Specification — Designed for use with a 0.25mm overbore cylinder, making this the correct ring set for engines that have been rebored to that oversize during a rebuild.
- Direct Fit for MT85 Rammers — Confirmed compatibility with the MT85 rammer series; installs into the EC12D engine without modification to pistons, bores, or connecting rods.
- Compression Restoration — Worn or broken piston rings cause blow-by, power loss, and oil burning; replacing with this genuine set restores cylinder pressure and returns impact force to spec.
- Genuine Multiquip OEM Part — Supplied as an authentic OEM component under part number 1612350207, providing confidence in material grade, dimensional accuracy, and long-term durability.
Piston rings seal the combustion chamber between the piston and cylinder wall, maintaining compression pressure that drives the rammer's impact stroke. They also control oil consumption by scraping excess oil back down the cylinder bore. When rings wear, lose tension, or break, combustion gases escape past the piston — a condition known as blow-by — causing a noticeable drop in compaction force, rough running, and increased oil use. Replacing the ring set is a standard engine rebuild step and is critical to restoring full performance in a rammer that has accumulated significant service hours.
