The Multiquip 1612350307 Ring Set 0.50mm is a genuine OEM component designed for MT85 series rammers. Sourced directly from Multiquip, this ring set is manufactured to the exact tolerances required by the EC12D engine used in the MT85 tamper, ensuring a proper fit during engine rebuild or oversize bore service. As a genuine OEM part, it carries the same specifications as the original factory-installed component, so you can restore engine compression with confidence. If your MT85 rammer is burning oil, losing power, or showing signs of cylinder wear, this 0.50mm oversize ring set is the correct service replacement to bring it back to working condition.
Key Features
- Oversize Bore Specification: — Cut to a 0.50mm oversize profile, matching the service dimension for bored or honed EC12D engine cylinders on the MT85.
- Genuine OEM Construction: — Manufactured to Multiquip's original material and dimensional standards, delivering the ring tension and seating behavior the EC12D engine requires.
- Direct Engine Rebuild Fit: — Designed as a complete ring set for the EC12D powerhead, dropping in during a top-end rebuild without secondary machining when the bore is correctly sized.
- MT85 Rammer Compatibility: — Confirmed fitment for the Multiquip MT85 tamper rammer, simplifying parts lookup during engine service.
- Compression and Oil Control Restored: — Worn or broken piston rings allow combustion gases to blow past the piston and oil to enter the combustion chamber; replacing them with this ring set restores proper compression and eliminates oil consumption.
Piston rings seal the gap 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 produces full power, and scraping excess oil off the cylinder wall to prevent it from burning in the combustion chamber. When rings wear, break, or lose tension, the engine loses compression, burns oil, produces excessive smoke, and eventually fails to develop enough force to drive the rammer's impact mechanism effectively. Installing a correctly sized oversize ring set during a cylinder rebore service restores the tight seal the engine needs to run at full output.
