Multiquip 21E23401H3 Piston ER12 - OEM Replacement Part

The piston assembly is a critical engine component in Multiquip rammer units, responsible for converting combustion energy into the mechanical force needed to drive the ramming action. When a piston fails or shows signs of wear—such as loss of compression, excessive blow-by, hard starting, or reduced ramming power—replacement with a genuine OEM piston ensures your equipment returns to factory specifications and performance standards.

The Piston ER12 (part number 21E23401H3) is precision-engineered to exact Multiquip tolerances for proper fit, sealing, and durability in demanding compaction applications. Using genuine OEM pistons maintains proper compression ratios, heat dissipation, and wear characteristics that aftermarket alternatives cannot match. This component is essential for major engine rebuilds or when addressing performance issues related to piston wear or damage.

This piston is compatible with the following Multiquip rammer models:

• MTX60SD
• MTX60SF
• MTX70SD
• MTX80SD
• MTX80SF
