The Wacker Neuson Fan Type Lock Washer is a genuine OEM component designed for the BPU 5045A and BPU 3545A reversible vibratory plate compactors. As a factory-sourced part, it is manufactured to the exact material and dimensional tolerances specified for these machines, ensuring a correct installation with no guesswork. This washer is confirmed compatible with both the BPU 5045A (50 kN) and BPU 3545A (35 kN) reversible plate compactor models.
Key Features
- Genuine OEM Hardness and Bite: — Fan type lock washers rely on precise tooth geometry and tempered spring steel to grip fastener faces securely; this OEM part meets the exact hardness and tooth profile required for the application.
- Drop-In Installation: — Matches the original bore size and outer diameter exactly, so it seats correctly against the mating fastener and surface without fitting adjustments.
- Confirmed BPU Compactor Fitment: — Verified fit for BPU 5045A and BPU 3545A reversible vibratory plate compactors, covering both the 35 kN and 50 kN output variants in the BPU gasoline-powered compaction range.
- Vibration Resistance Built In: — In high-vibration compaction equipment, standard washers can back off over time; the fan tooth design bites into the fastener face to maintain clamp load through continuous machine operation.
- Fastener Integrity Under Load: — A worn or missing lock washer in a high-cycle compactor can allow fasteners to loosen, leading to component misalignment or accelerated wear on surrounding hardware; replacing it promptly protects the broader assembly.
A fan type lock washer — also called a star or serrated lock washer — is a hardened, toothed washer placed under a bolt head or nut to prevent loosening caused by vibration and dynamic loading. The serrated teeth deform slightly when the fastener is torqued down, biting into both the fastener face and the mating surface to create mechanical resistance against rotation. In vibratory compaction equipment like the BPU series, where the machine generates continuous oscillating force during operation, maintaining consistent fastener torque is critical; a failed or absent lock washer can allow bolts to back out gradually, compromising the integrity of the assembly it secures.
