The Wacker Neuson Suction Tube is a genuine OEM component designed for CRT46 and CRT36 series ride-on concrete power trowels, including the CRT46KHN, CRT46KHO, CRT46ASO, CRT36ASO, and CRT36ASN models. Sourced directly from Wacker Neuson, this part is manufactured to the exact specifications of the original, ensuring a correct, trouble-free installation. Keeping the fuel or fluid delivery path fully intact is critical on a ride-on trowel operating under sustained load, and the delivers the same construction and fit as the factory-installed component. Confirm your model number before ordering to ensure full compatibility with your machine.
Key Features
- Genuine OEM Construction: — Manufactured to original Wacker Neuson tolerances, ensuring the tube maintains correct flow rate and sealing integrity under operating conditions.
- Direct Drop-In Replacement: — Engineered to match the original routing, diameter, and connection points, so installation follows the same procedure as the factory part.
- Broad CRT Series Fitment: — Verified for CRT46KHN, CRT46KHO, CRT46ASO, CRT36ASO, and CRT36ASN ride-on concrete trowel models.
- Sustained Flow Integrity: — A correctly functioning suction tube maintains uninterrupted fluid draw; a cracked or deteriorated tube can cause air ingestion, erratic operation, or system starvation.
- Fuel System Reliability: — On ride-on trowels where consistent engine performance directly affects finish quality, a sound suction tube is a critical link in the fuel delivery circuit.
The suction tube draws fuel or fluid from the reservoir and delivers it to the engine or pump system, acting as the first link in the machine's fluid supply circuit. If the tube develops a crack, collapse, or loose connection, air can enter the line, causing hard starting, rough running, or complete loss of prime. On a ride-on concrete trowel like the CRT46 or CRT36 series — where the operator depends on consistent engine output to achieve an even finish pass — a compromised suction tube can disrupt the entire workflow and result in costly surface defects.
