Key Features
- Genuine OEM Construction — Manufactured to the same dimensional and material tolerances as the original head piece, ensuring correct sealing, alignment, and load-bearing performance in the roller assembly.
- Direct-Fit Replacement — Engineered to install in the same position and orientation as the factory part, with no modification to mounting points or surrounding components required.
- Confirmed Roller Fitment — Compatible with RW1403HF, RW1404, and RW1404MR rollers, including RW1404MR units from S/N 326075 and up.
- Structural Integrity Maintained — A correctly functioning head piece keeps critical internal components properly seated and aligned; a worn or damaged unit can lead to vibration loss, misalignment, or premature wear on adjacent parts.
- Multiquip OEM Part Number Verified — Listed under Multiquip part number 51664, ensuring you receive the correct component for your specific RW roller model.
The head piece is a structural and functional component within the roller's vibration or drive assembly, responsible for capping, housing, or transmitting force between internal parts depending on its location in the machine. It provides a precise mating surface that keeps the assembly contained and properly aligned during operation. When the head piece becomes cracked, worn, or damaged, it can compromise the integrity of the surrounding assembly, leading to increased vibration, fluid loss, or accelerated wear on connected components — making timely replacement essential for consistent compaction performance.
