The Multiquip 4180034 is a genuine OEM Piston Pin RW-1402,3 designed for the RW-1402 RAMMAX ride-on roller. As a factory-sourced component, this pin is manufactured to the exact tolerances required by Multiquip, ensuring it seats correctly within the piston assembly without any guesswork. Sourcing a genuine OEM part like the 4180034 means you are replacing a worn or failed component with the same specification that left the factory, keeping your RW-1402 operating as intended.
Key Features
- Exact OEM Tolerancing — Manufactured to the precise diameter and hardness specifications required for correct piston travel and load transfer in the RW-1402 hydraulic system.
- Drop-In Fitment for RW-1402 — Engineered specifically for the RAMMAX RW-1402 ride-on roller; seats directly into the existing piston bore with no machining or shimming required.
- Confirmed RW-1402 Compatibility — Verified fitment for the RW-1402 series RAMMAX roller, so you can order with confidence against your machine's model code.
- Sustained Compaction Consistency — A correctly fitted piston pin maintains proper compression stroke geometry, preserving the drum's vibration output and compaction performance across asphalt and subbase applications.
- Genuine Multiquip OEM Part — Supplied directly through the Multiquip OEM parts chain, meeting the same material and dimensional standards as the original component your machine shipped with.
The piston pin is a critical link in the engine or hydraulic motor's reciprocating assembly, connecting the piston to the connecting rod and transferring force through each compression and power stroke. When a piston pin wears, develops play, or seizes, it causes knocking, loss of power output, and accelerated wear on the surrounding bore and rod bearing — issues that can quickly escalate into major engine or motor damage if left unaddressed. Replacing a worn pin with a correctly dimensioned OEM component like the Multiquip 4180034 restores proper mechanical clearance and protects the surrounding assembly from secondary wear.
