The Multiquip 351420390 Piston Pin Dr-50 is a genuine OEM component designed for the MT60H2 rammer. As an authentic Multiquip replacement part, 351420390 is manufactured to the same specifications as the original, ensuring a direct, correct-fit installation into the engine assembly. This piston pin is the right choice when rebuilding or servicing the MT60H2's Robin/Subaru-powered engine to restore it to full operating condition.
Key Features
- Genuine OEM Construction — Manufactured to the exact material hardness and dimensional tolerancing required for a piston pin application, ensuring proper load transfer and wear resistance under repeated impact cycles.
- Direct Engine Assembly Fit — Engineered to drop into the piston and connecting rod bores of the MT60H2 engine without rework, aligning correctly with the wrist pin clips and bore geometry of the original design.
- MT60H2 Specific Compatibility — Confirmed fitment for the Multiquip MT60H2 rammer, the Robin/Subaru-powered model in the Multiquip tamper lineup that does not share engine components with the Honda-powered MTX series.
- Restored Engine Efficiency — A worn or undersized piston pin causes piston slap, increased blow-by, and loss of compaction force; replacing it with the correct OEM part restores the engine's compression and power stroke consistency.
- Long-Term Engine Integrity — OEM piston pins are held to tight hardness and finish tolerances that prevent premature wear against the connecting rod bushing and piston bore, extending the service life of the surrounding components.
The piston pin — also known as a wrist pin — connects the piston to the small end of the connecting rod inside the engine cylinder. It acts as the pivot point that transfers the force of combustion down through the connecting rod to the crankshaft, driving the machine's ramming action. When a piston pin wears, becomes scored, or develops excessive clearance in its bore, it introduces knocking, vibration, and a loss of power that will progressively damage the piston, connecting rod bushing, and cylinder wall if left unaddressed.
