The Multiquip 366459910 Piston Pin Plug is a genuine OEM component designed for MTX70HD, MTX70HDR, MTX70HF, and MTX80HDR series rammers. As an original Multiquip part, it is manufactured to the exact tolerances required for proper piston assembly function in these machines. This plug is a direct-fit replacement, confirming compatibility with the MTX70 and MTX80 rammer families. Sourcing the correct OEM piston pin plug helps maintain compression integrity and protects the surrounding cylinder components from premature wear.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to exact dimensional tolerances to properly retain the piston pin and prevent lateral movement within the connecting rod bore.
- Direct-Fit Replacement — Designed to drop into the piston assembly without machining or modification, matching the original component profile and retention method.
- Broad MTX Rammer Compatibility — Confirmed fit for MTX70HD, MTX70HDR, MTX70HF, and MTX80HDR rammer models.
- Protects Cylinder and Bore Surfaces — A correctly seated piston pin plug keeps the pin centered and secure, preventing scoring of the cylinder wall or connecting rod damage caused by a migrating pin.
- Fuel System and Compression Safety — Maintaining a properly retained piston pin is critical to stable compression and consistent rammer stroke output, directly affecting compaction performance on the jobsite.
The piston pin plug is a small retention component seated at the end of the piston pin bore, where it holds the wrist pin in place and prevents it from shifting laterally during the rammer's high-frequency reciprocating stroke. Without a secure plug, the pin can migrate toward the cylinder wall, causing rapid scoring and catastrophic bore damage. On high-cycle compaction equipment like the MTX rammer family, this part experiences significant repetitive loading, making correct installation of an OEM-spec replacement essential to long-term piston assembly health.
