The Wacker Neuson Air Filter Cover Assembly is a genuine OEM component designed for the RD12A-90 tandem roller series, GS12Ai, CRT36-26A and CRTv36-26A power trowels, and the GPS9700A. As a direct factory replacement, this cover assembly carries the same specifications and fit as the original part — ensuring the air filtration system on your machine operates exactly as designed. It is compatible across multiple RD12A-90 configurations including foldable ROPS and standard setups, as well as both standard and wheel-kit-equipped CRT36-26A and CRTv36-26A trowel variants. If you're returning a machine to service after maintenance or replacing a cracked or damaged cover, part is the correct OEM solution.
Key Features
- Genuine OEM Enclosure Integrity — Manufactured by Wacker Neuson to the same tolerances as the original, ensuring the cover seals and protects the air filter element without gaps or misalignment that could allow unfiltered air to enter the system.
- Drop-In Fitment Across Multiple Configurations — Mounts directly to the existing air filter housing with no modification to mounting points or hardware, whether you're working on a roller or a power trowel variant.
- Wide Model Coverage — A single part number covers the RD12A-90 roller series, GS12Ai, CRT36-26A and CRTv36-26A trowels (standard, wheel kit, and foldable ROPS builds), and the GPS9700A.
- Protects Engine Air Quality — A correctly seated cover keeps contaminants, moisture, and debris away from the filter element. A cracked or missing cover can compromise filtration and accelerate engine wear on high-cycle equipment.
- Verified OEM Part Number — Ordering by part number 5000226485 ensures you receive the exact Wacker Neuson assembly listed in the factory parts diagram — no guesswork on cross-references or fitment.
The air filter cover assembly forms the outermost protective layer of the engine's air intake system. Its job is to shield the air filter element from physical damage, water ingress, and heavy dust loading during operation — particularly important on compaction and finishing equipment that works close to the ground where debris and particulate levels are high. When the cover is cracked, broken, or missing, the filter element is exposed and can be bypassed entirely, allowing unfiltered air to reach the engine and causing premature cylinder, piston, and valve wear. Replacing a damaged cover promptly is one of the lowest-cost ways to protect the engine from avoidable long-term damage.
