The Multiquip 51621 is a genuine OEM Substructure P48K2B designed for Multiquip roller models MRH800GS, MRH601DS, and RW3010. As a factory-sourced component, 51621 is manufactured to the exact specifications required by these machines, ensuring a direct, correct-fit installation with no guesswork. Sourced through DHS Equipment as an authorized Multiquip parts supplier, this genuine OEM part gives you the confidence that you are installing the right component the first time. Verify your model number against the fitment list before ordering to confirm compatibility.

Key Features

• Genuine OEM Construction: — Manufactured to Multiquip's original engineering specifications, delivering the structural integrity and dimensional accuracy expected of a load-bearing substructure component.
• Direct Replacement Fit: — Engineered as a drop-in replacement for the original Substructure P48K2B, aligning with existing mounting points and hardware on compatible roller models.
• Confirmed Roller Fitment: — Fits MRH800GS, MRH601DS, and RW3010 Multiquip roller models; always confirm your model designation before ordering.
• Structural Reliability: — A sound substructure keeps the roller's core components properly supported and aligned; a compromised substructure can lead to vibration irregularities, component misalignment, and accelerated wear across the machine.
• Authorized Source: — Sold by DHS Equipment, an authorized Multiquip parts dealer, so the part you receive carries full OEM traceability and part number accuracy.

The substructure is a foundational structural assembly within the roller that supports and positions key operational components, maintaining proper alignment between the drum, drive system, and frame. It absorbs operational loads and vibration transmitted during compaction passes, holding everything in the correct geometric relationship for the machine to perform as intended. When the substructure is cracked, worn, or structurally compromised, other components can shift out of alignment, leading to uneven drum contact, increased stress on surrounding parts, and degraded compaction performance across the entire roller.
