Multiquip 21E23502H7 Piston Ring Set 0.25 Oversize ER120 - OEM Replacement Part

This oversized piston ring set restores compression and engine performance in Multiquip rammer engines that have been bored 0.25mm over standard size during rebuild procedures. When an engine experiences loss of power, excessive oil consumption, or blow-by gases, cylinder wear often requires boring to the next oversize and installing matching oversized piston rings to restore proper sealing between the piston and cylinder wall.

The ER120 engine used in MTX-series rammers relies on proper piston ring seal to maintain the compression needed for the powerful circular motion that creates the consecutive impact force required for soil compaction in road work, embankments, reservoirs, and backfilling applications. This 0.25mm oversize ring set is specifically engineered for engines that have been professionally machined to accept oversize pistons, ensuring proper clearances and compression seal are restored to factory specifications.

Compatible with the following Multiquip rammer models:

• MTX60SD
• MTX70SD
• MTX80SD
• MTX80SF
