The Multiquip EM504451 Disk 6X12X1.2 DIN 988 is a genuine OEM shim disk designed for AR13H, AR13HC, AR13HA/HAR, QP3TZ, QP2TZ, MVH408DZ, and MVH308DZ equipment. As a factory-sourced component, EM504451 is manufactured to the DIN 988 standard, ensuring dimensional accuracy across every application it serves. This single part spans multiple Multiquip equipment families — asphalt ride-on rollers, trash pumps, and heavy-duty reversible plate compactors — making correct part number verification essential before ordering. DHS Equipment supplies this as a genuine Multiquip OEM part, so you receive the same specification disk installed at the factory.
Key Features
- DIN 988 Dimensional Compliance — Manufactured to the DIN 988 shim standard, delivering consistent thickness and flatness tolerances that keep mating surfaces properly spaced and loaded.
- Genuine OEM Sourcing — Supplied directly from Multiquip as an OEM component, meaning material grade and dimensional spec match the original part exactly as built.
- Broad Multi-Family Fitment — Confirmed for AR13H, AR13HC, and AR13HA/HAR asphalt ride-on rollers, QP3TZ and QP2TZ trash pumps, and MVH408DZ and MVH308DZ reversible plate compactors.
- Correct Axial Clearance Control — A properly spec'd shim disk maintains the designed axial clearance between rotating and stationary components, preventing premature bearing and shaft wear.
- Drop-In Replacement — Matches the original profile and thickness, allowing direct installation without machining or sizing adjustments at the time of service.
A DIN 988 shim disk is a precision-ground flat washer used to set or restore the correct axial spacing between rotating assemblies — such as shafts, bearings, and housings — inside mechanical equipment. By occupying a defined gap, the shim disk controls end-play and preload, which directly affects how smoothly and reliably the assembly operates under load. When a shim disk wears thin, becomes distorted, or is omitted during reassembly, the resulting misalignment accelerates bearing wear, increases vibration, and can lead to premature failure of surrounding components.
