The Multiquip 354446170 Pin 6D-85L MT-85H is a genuine OEM component designed for Multiquip rammer models including the MTX80HDR, MTX70HDR, MTX70HD, MTX70HF, and MT85. As a factory-sourced part, 354446170 is manufactured to the exact tolerances required for proper fitment and function within the rammer's drive assembly. Sourcing a genuine OEM pin ensures you're installing the same part the machine was originally built with, maintaining the integrity of the assembly and avoiding the clearance issues that come with imprecise replacements. Confirm your model code against the fitment list before ordering to ensure this is the correct pin for your unit.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the exact diameter and length specification of the original pin, ensuring proper load transfer and articulation within the rammer drive linkage.
- Drop-In Replacement — Matches the original mounting configuration on compatible rammer models, slipping directly into existing bores without reworking surrounding components.
- Broad Rammer Compatibility — Confirmed fit across MTX80HDR, MTX70HDR, MTX70HD, MTX70HF, and MT85 Multiquip rammer models.
- Maintains Drive Assembly Integrity — A correctly fitted pin keeps the rammer's internal linkage aligned and transmitting impact energy efficiently; a worn or undersized pin introduces slop that degrades compaction output and accelerates wear on adjacent components.
- Structural Safety in High-Impact Applications — Rammer drive pins operate under sustained percussive load cycles; using a genuine OEM pin rated for this application reduces the risk of premature shear or deformation under working conditions.
A drive pin in a rammer serves as a critical pivot and retention point within the machine's internal linkage, connecting moving components and transmitting the cyclic impact force generated by the engine down through the foot assembly. Under normal operation, rammer pins are subjected to thousands of impact cycles per minute, making material grade and dimensional accuracy essential to longevity. When a pin wears, becomes loose, or fails, the result is increased vibration, misalignment of the drive mechanism, and eventual damage to surrounding components — making timely replacement with the correct part essential to keeping the rammer performing at full compaction force.
