The Multiquip 2842351307 Piston Ring Set 0.50MM is a genuine OEM component designed for MT55F, MTR40F, and MTR40SF series rammers. This is a 0.50MM oversized ring set, intended for use during engine rebuilds where the cylinder bore has been honed or bored to accept the larger piston diameter. As a genuine OEM part, it is manufactured to the exact tolerances required to restore proper compression and oil control in Multiquip rammer engines. Sourcing the correct ring set by 2842351307 is critical to a successful rebuild — and the part ensures you have the right specification the first time.
Key Features
- Oversized Rebuild Specification: — Sized at 0.50MM over standard, this ring set is matched to bored or honed cylinder applications, ensuring correct piston-to-wall clearance for proper compression sealing.
- Genuine OEM Construction: — Manufactured to Multiquip's exact material and dimensional standards, delivering the ring tension and surface finish required for dependable engine performance in rammer applications.
- Drop-In Engine Rebuild Fitment: — Engineered specifically for the MT55F, MTR40F, and MTR40SF rammer models, this set installs without modification when used with the correct oversized piston.
- Restores Compression and Oil Control: — Worn or broken piston rings cause loss of compression, excessive oil consumption, and hard starting. A fresh ring set brings the engine back to full power output and smooth operation.
- Fuel Efficiency and Power Output: — Properly seated piston rings maintain the combustion seal that drives the rammer's impact energy — a compromised seal means reduced compaction force and higher fuel burn.
Piston rings form the seal between the piston and the cylinder wall, maintaining compression in the combustion chamber while preventing engine oil from entering and burning in the combustion process. In a rammer engine, which operates under high-cycle, high-vibration conditions, rings wear faster than in stationary applications — leading to reduced impact energy, increased oil consumption, and difficult starting. When a cylinder is bored or honed beyond the standard diameter during a rebuild, a standard-size ring set will not seal correctly; an oversized set like the 0.50MM this part is required to restore the correct fit and combustion seal.
