The Wacker Neuson Flywheel is a genuine OEM Flywheel designed for the BL744ch, BL744h, BL742h, BL744c, BL744 EX, and BL742 EX Backhoe Loader series. As a factory-sourced component, it meets the exact tolerances and balance specifications required by these machines, ensuring proper engine operation from the moment it's installed. This is the same part supplied through authorized Wacker Neuson service channels, giving you full confidence in fitment accuracy across the entire BL700 series Backhoe Loader lineup.
Key Features
- OEM-Balanced Mass Specification — Manufactured to Wacker Neuson's exact rotational balance and mass tolerances, critical for smooth engine operation and bearing longevity in these Backhoe Loaders.
- Direct-Mount Replacement — Engineered to bolt directly onto the crankshaft flange of compatible BL700 series engines with no rework, machining, or adaptation to mating components.
- Broad BL700 Series Coverage — Confirmed fitment across BL744ch, BL744h, BL742h, BL744c, BL744 EX, and BL742 EX Backhoe Loader models under a single part number.
- Protects Drivetrain Components — A correctly balanced flywheel reduces vibration loads transmitted to the crankshaft, clutch, and transmission, extending the service life of surrounding components.
- Genuine OEM Sourcing — Part number 5100033995 is an authentic Wacker Neuson component, not a pattern copy — material grade, ring gear engagement, and mounting geometry are factory-verified.
The flywheel is a heavy rotating disc mounted directly to the engine crankshaft. Its primary job is to store rotational energy between power strokes, smoothing out the engine's power delivery and keeping it running evenly under varying load conditions — essential in a Backhoe Loader that cycles between dig, swing, and travel constantly. The flywheel also carries the ring gear that the starter motor engages to crank the engine, and it provides the mating surface for the clutch assembly. When a flywheel is cracked, out of balance, or has a worn ring gear, symptoms include rough engine vibration, difficult starting, clutch chatter, and accelerated wear on bearings and mounts — all of which point to immediate replacement.
