Key Features
- OEM-Grade Sealing Integrity — Manufactured to Wacker Neuson's original material and dimensional tolerances, ensuring the crankcase is properly sealed against oil leaks and contaminant ingress.
- Direct Bolt-On Replacement — Matches the original mounting pattern and gasket surface exactly, so installation follows the same procedure as the factory-fitted cover with no rework needed.
- Broad LTN Series Coverage — Compatible with a wide range of LTN4Y and LTN5Y variants, including SA, RH, CH, UK, 60 Hz, 120V/60Hz, Yp, Ypa, Ypk, and HD configurations.
- Protects Engine Internals — A correctly fitted crankcase cover keeps engine oil contained and external debris out, protecting crankshaft bearings and internal components from accelerated wear.
- Genuine Wacker Neuson Part — Part number 5100075890 is an authentic OEM component, giving you confidence that fitment, material grade, and performance characteristics match the original specification.
The crankcase cover seals the side or bottom of the engine's crankcase, enclosing the crankshaft, bearings, and oil within a controlled environment. It plays a critical role in maintaining proper oil pressure and preventing contamination from dust, moisture, or debris that could accelerate internal wear. When a crankcase cover cracks, warps, or its sealing surface is compromised, oil leaks follow quickly — and continued operation without a properly sealed crankcase risks serious engine damage and premature failure.
