Multiquip 21E23503H7 Piston Ring Set 0.50 Oversize - OEM Replacement Part

This oversize piston ring set restores compression and engine performance in worn Multiquip rammer engines, specifically sized at 0.50mm oversize for cylinders that have been bored during major engine rebuilds. When your MTX series rammer shows symptoms of reduced power, excessive oil consumption, or difficult starting, worn piston rings are often the culprit requiring replacement during comprehensive engine overhaul procedures.

Designed for the Robin ER120D series gasoline engines used in Multiquip MTX rammers, this genuine OEM piston ring set ensures proper sealing between the piston and cylinder wall to maintain optimal compression ratios and engine efficiency. The 0.50mm oversize specification is critical for cylinders that have been machined beyond standard tolerances due to wear or scoring. Using the correct oversize ring set after cylinder boring is essential for restoring factory performance specifications and extending engine service life.

Compatible with the following Multiquip rammer models:

• MTX60SD
• MTX60SF
• MTX70SD
• MTX80SD
