The Wacker Neuson is a genuine OEM Kubota D1105 LTN8K Engine designed for the LTN8K and LTN8K-V S series light towers. As a direct-from-manufacturer replacement, this engine assembly carries the same specifications as the original unit installed at the factory, ensuring a verified fit across multiple LTN8K configurations including Tier 4 Final, cold weather, and custom 60 Hz variants. If your light tower is losing power output, running rough, or has suffered engine failure, part number is the correct OEM replacement to restore full operation. Confirm your machine's model and serial number against the fitment list before ordering to ensure compatibility with your specific configuration.
Key Features
- Genuine OEM Kubota Powerplant — Sourced directly from Wacker Neuson, this engine meets the original displacement, compression, and output specifications of the D1105 unit — no guesswork on power rating or interface dimensions.
- Drop-In Fitment for LTN8K Platforms — Engine mounting points, fuel connections, and electrical interfaces match the original LTN8K frame layout, allowing straightforward swap-out without custom fabrication.
- Broad LTN8K Series Coverage — Fits LTN8K, LTN8K-V, LTN8K-LT (cold weather), and LTN8K-V S configurations across standard, custom, and Tier 4 Final emissions builds.
- Sustained Generator Output — A correctly functioning D1105 engine maintains steady RPM under load, which is critical for stable voltage output from the light tower's generator head. Engine wear or failure causes voltage fluctuation and lamp flicker or shutdown.
- Emissions-Compliant Build — Tier 4 Final compatible variants meet current EPA non-road emissions standards, keeping your light tower legally operable on regulated worksites.
The Kubota D1105 is a three-cylinder, liquid-cooled diesel engine that serves as the prime mover for the LTN8K light tower's onboard generator. It drives the generator head at a controlled speed to produce the electrical output needed to power the tower's high-output lamps. When the engine runs below spec — due to wear, overheating, or mechanical failure — the generator cannot maintain consistent output, resulting in reduced lighting performance or complete tower shutdown. Replacing a failed or end-of-life engine with the correct OEM unit restores the light tower to its rated electrical output and operational runtime.
