The Wacker Neuson Inlet Radiator Duct is a genuine OEM component designed for CB14B-900 and CB14B-1000 series soil and asphalt compaction machines. Sourced directly from Wacker Neuson, this part matches the original specification exactly — same geometry, same material grade, same fitment as the part that left the factory. It covers the full CB14B family across multiple configurations, making it the straightforward choice whether you're completing a scheduled service or addressing a damaged duct in the field. Confirm your machine's model and serial number against the fitment list before ordering to ensure a direct replacement.
Key Features
- OEM Airflow Path Integrity — Manufactured to the original duct profile, ensuring the cooling air channel between the inlet and radiator core is maintained without gaps, warping, or misalignment that can compromise thermal performance.
- Direct Drop-In Replacement — Matches the original mounting points and duct geometry of the CB14B series, so installation follows the same procedure as the factory-fitted part.
- Broad CB14B Series Coverage — Compatible with CB14B-900 and CB14B-1000 configurations across multiple serial number ranges, covering a wide span of the CB14B compactor family.
- Protects Engine Cooling Efficiency — A structurally sound inlet duct channels airflow consistently to the radiator; a cracked or collapsed duct allows hot air recirculation, which can drive coolant temperatures up and shorten engine service intervals.
- Genuine Wacker Neuson Part — Supplied as an authentic OEM component under part number 5200004056, backed by Wacker Neuson's parts program for confidence in origin and consistency.
The inlet radiator duct is a formed air-channeling component that directs outside air toward the radiator core on liquid-cooled compaction equipment. By creating a defined airflow path, it prevents hot exhaust air from recirculating back into the cooling system — a condition that causes the engine to run hotter than intended and can accelerate wear on coolant, belts, and seals. When the duct cracks, warps, or pulls away from its mounting, cooling efficiency drops noticeably; replacing it promptly restores the thermal management the engine relies on during sustained compaction work.
