The Wacker Neuson -01 Air Filter Assembly is a genuine OEM component designed for the CRT48-33K and CRT48-33K DF ride-on concrete trowels. As a direct Wacker Neuson OEM part, the -01 is manufactured to the exact specification required by these machines, ensuring a correct, hassle-free installation. This assembly covers both the standard CRT48-33K and the Dual-Fuel CRT48-33K DF variants, making it the go-to replacement for operators running either configuration. Keep a verified OEM replacement on hand to maintain engine protection and consistent finishing performance on every pour.
Key Features
- Genuine OEM Filtration Integrity — Engineered to the exact media density and sealing geometry specified for the CRT48-33K engine, ensuring consistent particulate capture where an incorrect filter can allow abrasive dust to reach internal engine components.
- Direct-Fit Installation — Matches the original housing dimensions and connection interface of the CRT48-33K air intake system, dropping straight in without modification to the filter housing or mounting hardware.
- Broad CRT48-33K Fitment — Confirmed for the CRT48-33K and CRT48-33K DF (Dual-Fuel) ride-on concrete trowels, covering both fuel configurations within the 48-inch CRT family.
- Engine Air Protection — A properly functioning air filter assembly allows the engine to breathe clean, metered airflow; a clogged or deteriorated filter starves the engine of air, causing rough running, increased fuel consumption, and accelerated internal wear.
- Verified OEM Part Number — Sourced directly from Wacker Neuson as part number 5062263-01, eliminating the guesswork of cross-referencing alternative part numbers for these trowel models.
The air filter assembly is responsible for removing airborne dust, concrete particulate, and debris from the incoming air charge before it enters the engine. On a ride-on concrete trowel like the CRT48-33K, operating conditions place the engine at low height over freshly finished slabs where fine cement dust is constantly present, making a fully sealed, correctly rated filter assembly critical to engine longevity. When the filter media becomes saturated or the housing seal fails, contaminated air bypasses filtration and accelerates cylinder and valve wear, leading to loss of power and premature engine damage.
