The Wacker Neuson 5100031607 is a genuine OEM Oil Filler Cap designed for the BPS series single-direction vibratory plate compactors. Sourced directly from Wacker Neuson, this cap is an exact match for the original component, ensuring a proper seal and correct fitment across a wide range of BPS models including the BPS1030A, BPS1135A, BPS1340A, BPS1550A, and BPS2050A — in both US and EU configurations. As a genuine OEM part, the 5100031607 meets the same specifications as the cap installed at the factory, so there is no guesswork when it comes to thread pitch, cap diameter, or sealing integrity. Keep a spare on hand to protect your plate compactor's engine oil from contamination and to stay ready for quick servicing in the field.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to the original specification, this cap delivers the same airtight, vibration-resistant seal as the factory-installed component, protecting engine oil from dirt and moisture ingestion.
- Direct-Thread Replacement — Matches the original thread pitch and cap diameter exactly, dropping straight into the oil filler opening with no modification to the filler neck or surrounding hardware.
- Broad BPS Series Compatibility — Fits BPS1030A, BPS1030Aw, BPS1135A, BPS1135Aw, BPS1340A, BPS1340Aw, BPS1340Aws, BPS1550A, BPS1550Aw, BPS1550Aws, BPS2050A, and BPS2050Aw plate compactors in both US and EU variants.
- Engine Protection Where It Starts — A properly sealing oil filler cap keeps contaminants out of the crankcase and prevents oil vapor from escaping, both of which directly affect engine longevity on high-vibration compaction equipment.
- Part Number Verified — OEM part number 5100031607 cross-references directly against the listed BPS model configurations, giving you confidence you are ordering the correct cap for your machine.
The oil filler cap closes and seals the engine's oil filler opening, preventing dirt, debris, and moisture from entering the crankcase during operation and storage. On vibratory plate compactors like the BPS series — which generate sustained, high-frequency vibration — a worn or cracked cap can work loose over time, leading to oil contamination or gradual oil loss that accelerates internal engine wear. Replacing a damaged or missing cap with the correct OEM part, such as the Wacker Neuson 5100031607, restores the proper seal and keeps the lubrication system protected between service intervals.
