The Multiquip EM627 Washer Star 1" is a genuine OEM component designed for RW1810 and RW3010 RAMMAX walk-behind rollers. Sourced directly from Multiquip, EM627 delivers the exact material grade, tooth profile, and dimensional tolerancing required for a correct, secure installation. This star washer is a verified fit for the RW1810 and RW3010 models, giving you confidence that the part you receive matches the original specification. Keeping the correct hardware in place is essential to maintaining proper clamping force and fastener integrity on your roller.
Key Features
- Genuine OEM Tooth Engagement: — Manufactured to the exact tooth count and material hardness spec of the original, ensuring full locking contact under load.
- Direct-Fit Installation: — Matches the 1" bore and profile of the original hardware, dropping in without modification to fastener assemblies on the RW1810 and RW3010.
- Confirmed Fitment: — Verified for Multiquip RW1810 and RW3010 RAMMAX walk-behind rollers using Multiquip OEM part number EM627.
- Fastener Security: — Star washers resist loosening caused by vibration — critical on compaction equipment that operates under continuous dynamic load cycles.
- Correct Hardware, Every Time: — Using the OEM-specified washer prevents fastener backing-out, uneven clamping, and potential damage to mating surfaces during operation.
A star washer — also called a lock washer — is a hardened, toothed fastener component that sits between a bolt head or nut and the mating surface. The serrated teeth bite into both surfaces when the fastener is torqued down, resisting rotation and preventing the assembly from loosening under vibration or repeated load cycles. On walk-behind rollers like the RW1810 and RW3010, where the machine produces sustained compaction vibration, maintaining correct fastener clamping force is critical to safe and consistent operation. A worn, damaged, or incorrect star washer can allow fasteners to back out gradually, leading to loose assemblies and accelerated wear on surrounding components.
