The Multiquip 8906509 Internal Tooth Washer RW-1402,3 is a genuine OEM component designed for the RW-1402 series walk-behind roller. Sourced directly from Multiquip, this washer meets the original equipment specification for proper fastener retention and secure assembly on the RW-1402. When you need an exact-match replacement to restore your roller to proper working order, the part delivers the fit and integrity the machine was built with.
Key Features
- Genuine OEM Tooth Geometry — Internal serrations are manufactured to the original Multiquip specification, ensuring the washer bites and holds under the fastener load conditions of the RW-1402 roller.
- Direct-Fit Replacement — Engineered to the same inner diameter, outer diameter, and thickness as the original, so it seats correctly without any rework or shimming.
- Confirmed RW-1402 Compatibility — Validated fitment for the Multiquip RW-1402 walk-behind roller, so you can order with confidence knowing this part is the correct part for your machine.
- Fastener Integrity Under Vibration — Internal tooth washers are specifically used where vibration is present; the serrated teeth grip both the fastener and the mating surface to prevent loosening during roller operation.
- Genuine OEM Sourcing — Supplied as an authentic Multiquip part, carrying the same material grade and dimensional quality as the washer installed at the factory.
An internal tooth washer functions by using inward-facing serrated teeth that dig into the underside of a bolt head or nut and into the mating surface when the fastener is tightened. This mechanical grip resists rotational loosening caused by vibration — a constant force on any compaction roller. When an internal tooth washer wears flat, loses its serrations, or is omitted during reassembly, fasteners in that joint can back out during operation, compromising the structural integrity of the assembly and potentially causing component damage or unsafe conditions.
