The Wacker Neuson Crankcase is a genuine OEM component designed for the LTN4Y and LTN5Y series light towers, including the LTN4Y, LTN4Y 60 Hz, LTN4Y SA, LTN4Y RH, LTN4Y 120V/60Hz, LTN5Y, LTN5Y SA, LTN5Y CH, LTN5Y UK, LTN5Yp, LTN5Yp HD, LTN5Ypa, and LTN5Ypk models. Sourced directly from Wacker Neuson, this part carries the same OEM specification as the original, ensuring it installs and seals exactly as intended without modification. Keeping the crankcase in sound condition is essential to engine integrity, oil containment, and overall machine reliability on the worksite.
Key Features
- OEM-Grade Sealing and Dimensional Accuracy — Cast and machined to the same tolerances as the original, ensuring proper oil retention and a leak-free fit between mating engine surfaces.
- Direct Drop-In Installation — All mounting points, bearing bores, and gasket surfaces match the original housing geometry, allowing straightforward installation without rework or custom fitting.
- Broad LTN Series Coverage — Confirmed fit across the full LTN4Y and LTN5Y light tower families, including SA, RH, 60 Hz, 120V/60Hz, CH, UK, Yp, Ypa, Ypk, and HD variants.
- Protects Core Engine Components — A structurally sound crankcase maintains correct bearing alignment and oil pressure, preventing premature wear to the crankshaft, connecting rods, and internal bearings.
- Genuine Wacker Neuson OEM Part — Part number 5100075854 is an authorized Wacker Neuson component, giving you full confidence that fitment and material grades match the original equipment specification.
The crankcase forms the structural foundation of the engine, housing the crankshaft, main bearings, and the lower end of the cylinder assembly while containing the engine oil that lubricates all moving internal parts. It must maintain precise dimensional integrity to keep rotating components in correct alignment and to prevent oil from escaping the sealed system. When a crankcase cracks, warps, or develops porosity, oil loss and bearing misalignment follow quickly, leading to accelerated internal wear and potential engine failure if not addressed promptly.
