The Multiquip 63819 Locking Bolt is a genuine OEM replacement designed for RAMMAX walk-behind rollers including the RW1504HF, RW1404MR, and P33/24 series. As a factory-sourced component, it is manufactured to the exact tolerances and material specifications required for dependable service on these machines. Confirm your serial number range before ordering — this bolt fits RW1404MR units with serial number 326075 and up, and RW1504HF units up to serial number. DHS Equipment stocks genuine Multiquip OEM parts so you can get the right component and get back to work without guesswork.
Key Features
- Genuine OEM Material Grade — Sourced directly from Multiquip, this bolt meets the hardness and thread specification required to maintain secure clamping force under the vibration loads typical of walk-behind roller operation.
- Direct Drop-In Replacement — Engineered to the original thread pitch and shank dimensions, this bolt seats and torques correctly without any rework to the surrounding hardware.
- Confirmed Fitment for RAMMAX Roller Models — Compatible with RW1504HF (up to S/N 1534188), RW1404MR (S/N 326075 and up), and P33/24 HHMR-BD with blade — verify your serial number before ordering.
- Maintains Locking Integrity — A correctly installed locking bolt keeps critical roller assemblies positionally fixed during operation; a worn or missing bolt can allow unwanted movement, affecting compaction consistency and component longevity.
- Operational Safety Relevance — On compaction equipment, loose or failed locking hardware can compromise the stability of rotating or articulating assemblies — using the correct OEM specification bolt helps ensure the machine operates as designed.
A locking bolt is a fastener specifically designed to resist loosening under vibration, shock loads, and repeated mechanical stress. On RAMMAX walk-behind rollers, locking bolts secure assemblies that are subject to continuous vibration during compaction work — if one fails or backs out, it can allow movement in components that must remain fixed, leading to accelerated wear, misalignment, or loss of control over the affected assembly. Replacing a worn or damaged locking bolt with the correct OEM part restores the clamping integrity the machine was built with and prevents more costly secondary damage down the line.
