Multiquip 12000ZDJ305 Cylinder Barrel Assembly - OEM Replacement Part for Rammers

The cylinder barrel assembly is the core compression component in tamping rammers, converting circular motion into the powerful vertical impact force needed for soil compaction. This assembly houses the internal piston mechanism that generates the 2,653 to 3,080 lbf impact force and delivers 644-695 blows per minute during operation. When the cylinder barrel shows signs of wear, scoring, or loss of compression, the rammer will experience reduced impact force, inconsistent blow frequency, or failure to engage properly at full throttle.

This genuine OEM barrel assembly maintains the precise tolerances required for the oil bath lubrication system to function correctly. Proper cylinder function is critical for maintaining the 2-3.15 inch impact plate stroke that ensures effective soil compaction. Signs that replacement may be needed include excessive vibration, loss of compaction power, visible oil leaks from the cylinder area, or unusual mechanical noise during operation.

Compatible with the following Multiquip tamping rammer models:

• MT77HFR (Honda GXR120RT-KRB6 engine)
• MTX70HDR
• MTX80HDR
