The Wacker Neuson Crankshaft Complete is a genuine OEM component designed for LTN4Y and LTN5Y series light towers. Sourced directly from Wacker Neuson, this is the same crankshaft assembly installed at the factory — ensuring a direct, exact-fit replacement for the engine at the heart of your light tower. Compatible across a broad range of LTN4Y and LTN5Y variants including the LTN4Y 60 Hz, LTN4Y SA, LTN4Y RH, LTN4Y 120V/60Hz, LTN5Y, LTN5Y CH, LTN5Y UK, LTN5Yp, LTN5Yp HD, LTN5Ypa, LTN5Ypk, and LTN5Y SA models, this genuine OEM part takes the guesswork out of sourcing.
Key Features
- OEM-Matched Tolerances — Manufactured to the precise dimensional and balance specifications required for smooth engine operation in Wacker Neuson LTN-series light towers.
- Drop-In Engine Replacement — Installs directly into the engine block using the original mounting points and bearing journals — no machining or adaptation needed.
- Broad LTN4Y and LTN5Y Coverage — A single part number covering multiple variants including 60 Hz, SA, RH, 120V/60Hz, CH, UK, Yp, Ypa, Ypk, and HD configurations.
- Restores Full Engine Output — A worn or damaged crankshaft causes excessive vibration, power loss, and bearing failure; replacing it with a genuine part restores proper engine balance and full rated output.
- Genuine Wacker Neuson OEM Part — Part number 5100075804 is an authorized Wacker Neuson component, giving you full confidence in fitment accuracy and part longevity.
The crankshaft is the central rotating component of a combustion engine, converting the up-and-down motion of the pistons into the rotational force that drives the machine. In a light tower like the LTN4Y or LTN5Y series, a correctly functioning crankshaft is essential for smooth, consistent engine operation at the RPMs needed to power the lighting system. When a crankshaft wears, cracks, or develops journal damage, the result is rough running, abnormal vibration, accelerated bearing wear, and ultimately engine failure — making timely replacement critical to keeping the unit in service.
