As a direct factory replacement, EM632 meets the original material and dimensional specifications that Multiquip engineering requires for proper fastener retention across these roller platforms. Sourced through DHS Equipment as an authorized Multiquip parts distributor, you can order with confidence knowing you are receiving the correct, genuine OEM component for your machine.
Key Features
- Genuine OEM Material Grade — Manufactured to the same hardness and spring-tension spec as the original, ensuring the washer bites and holds under the vibration and load cycles typical of compaction roller operation.
- Correct 7/8" Inside Diameter — Sized to seat flush on the correct fastener without shimming or modification, dropping straight into place on compatible bolt and stud applications across these roller models.
- Broad Roller Compatibility — Confirmed fit for the RW1403HF, RW1404, RW1404MR, RW1504HF, RW1810, RW3010, and P33/24 FR/FC/FCR and HHMR-BD series RAMMAX rollers.
- Vibration Resistance — Lock washers on compaction equipment are subjected to continuous vibration that can work standard fasteners loose; using the correct OEM-spec washer maintains joint integrity and prevents fastener backing out during operation.
- Simple Service Part — A low-cost fastener that is often overlooked during maintenance but critical to keeping structural and mechanical connections secure; replacing worn or flattened washers at each service interval is a best practice for roller upkeep.
A lock washer is a hardened, spring-tension fastener component placed under a nut or bolt head to resist loosening caused by vibration and dynamic loading. On compaction rollers, where the entire machine operates through sustained vibration, maintaining tight mechanical connections is essential to structural integrity and safe operation. When a lock washer flattens, corrodes, or is missing entirely, fasteners can back out progressively, leading to loose assemblies, component misalignment, or hardware loss in the field.
