The Wacker Neuson is a genuine OEM 15.75 Dia Sickle Blade Fan designed for LTW20Z-1 and LTW20Z-3 series light towers. As a factory-original component, it is manufactured to the exact specifications required by the Isuzu Tier 4i engine cooling system used across these machines. This fan fits an extensive range of LTW20Z configurations, including standard, cold weather, custom, skidded, and V-series variants. When you need a straight-across replacement with no guesswork, part number is the correct choice.

Key Features

  • Genuine OEM Blade Profile: — Sickle blade geometry is engineered to deliver the correct airflow volume and velocity for the Isuzu Tier 4i cooling system — not a generic blade shape adapted from another application.
  • Exact 15.75-Inch Diameter: — The 15.75-inch diameter matches the factory-specified clearance envelope, ensuring the blade seats correctly within the shroud without rubbing or airflow bypass.
  • Broad LTW20Z Series Coverage: — Confirmed fitment across LTW20Z-1 and LTW20Z-3 variants, including V-series, cold weather, custom, and skidded configurations built to Tier 4i emissions standards.
  • Cooling System Integrity: — A correctly sized and balanced fan maintains consistent engine and alternator operating temperatures during extended light tower run cycles — a worn or cracked blade causes hot spots, uneven airflow, and eventual thermal shutdown.
  • Direct OEM Replacement: — Sourced from Wacker Neuson's authorized parts supply, part 5000178107 bolts into position using the existing hardware and hub interface on LTW20Z series engines.

The cooling fan on a light tower draws air across the engine radiator and alternator to regulate operating temperature during prolonged stationary run times — the exact conditions light towers are built for. On Isuzu Tier 4i-powered LTW20Z units, the sickle blade profile is specifically shaped to maximize airflow efficiency at the engine's operating speed range. A damaged, cracked, or out-of-balance fan blade reduces cooling capacity, increases engine load, and can lead to overheating faults or premature engine wear during overnight or extended jobsite deployments.
