The Wacker Neuson Crankcase Complete is a genuine OEM component designed for the LTN4Y and LTN5Y series light towers, including standard, SA, ME, HD, RH, CH, UK, and 60Hz variants. As a direct OEM replacement, this assembly is sourced from Wacker Neuson and built to the same tolerances and material specifications as the original unit installed at the factory. Compatibility spans a broad range of LTN4Y and LTN5Y configurations, making the correct choice across multiple regional and voltage-specific variants. When replacing a worn or damaged crankcase, using the genuine OEM assembly ensures all internal engine components seat and seal correctly from the first start.
Key Features
- OEM Casting and Machining Tolerances — Manufactured to Wacker Neuson's original bore and surface specifications, ensuring correct fit for all internal engine components including bearings, seals, and the crankshaft.
- Complete Assembly Ready to Install — Supplied as a complete crankcase unit, reducing the number of individual components you need to source and simplifying the rebuild process.
- Broad LTN Series Compatibility — Fits the LTN4Y and LTN5Y series in standard, SA, ME, HD, RH, CH, UK, 60Hz, and 120V/60Hz configurations, covering a wide range of Wacker Neuson light tower variants under a single part number.
- Structural Integrity for Engine Longevity — A sound crankcase maintains proper oil containment and bearing alignment; a cracked or warped crankcase leads to oil loss, vibration, and accelerated internal engine wear.
- Genuine Wacker Neuson OEM Part — Part number 5100075825 is an authorized Wacker Neuson component, ensuring correct fitment without guesswork or modification to mating parts.
The crankcase is the structural foundation of the engine — it houses the crankshaft, supports the cylinder bore, and contains the engine oil that lubricates all moving internal parts. Every major engine component, from the connecting rod and pistons to the main bearings and oil seals, depends on the crankcase for correct alignment and a sealed operating environment. When a crankcase cracks, warps, or suffers damage to its sealing surfaces, the engine loses oil pressure and internal alignment, which quickly leads to bearing failure, excessive blow-by, and ultimately a seized or destroyed engine.
