The Wacker Neuson Oil Cap Gasket is a genuine OEM component designed for the RD12A-90 tandem roller, CRT36-26A trowel, CRTv36-26A trowel, GS12Ai, and GPS9700A series machines. Sourced directly from Wacker Neuson, this part meets the same specifications as the original installed at the factory — ensuring a proper seal every time. Compatible across a broad range of Wacker Neuson compaction, troweling, and generator equipment, the is the correct replacement when your oil cap seal shows wear, cracking, or leakage.
Key Features
- OEM Sealing Material: — Manufactured to Wacker Neuson's exact material specification, delivering the correct compression and chemical resistance needed to seal engine oil effectively against heat and pressure.
- Direct Drop-In Replacement: — Seats flush against the oil cap and filler neck just like the original, requiring no trimming or fitment adjustments during installation.
- Broad Model Coverage: — Fits the RD12A-90 tandem roller series, CRT36-26A and CRTv36-26A trowels, GS12Ai, and GPS9700A — one part number across multiple Wacker Neuson equipment lines.
- Prevents Oil Contamination: — A properly seated oil cap gasket keeps dirt, debris, and moisture out of the oil fill port, protecting engine internals and maintaining clean lubricant.
- Genuine OEM Confidence: — Supplied as an authorized Wacker Neuson OEM part under part number 5000226444, so you know the fit and material grade are verified against the original design.
The oil cap gasket forms an airtight, fluid-tight seal between the oil filler cap and the engine's fill port. Its job is to prevent oil from weeping out around the cap during operation and to stop outside contaminants from entering the crankcase. When the gasket degrades — through heat cycling, compression fatigue, or chemical exposure — it can develop cracks or lose its seating profile, leading to oil seepage, dirty oil, and potential engine wear. Replacing it promptly with the correct OEM part keeps the lubrication system properly sealed and the engine protected.
