The Multiquip 1721504610 Flywheel Housing is a genuine OEM component designed for the BLW-400SSW welder. Sourced directly from Multiquip, this part meets the exact specifications of the original housing fitted at the factory, ensuring a correct, trouble-free installation. It is the recommended replacement for any BLW-400SSW unit showing a cracked, damaged, or worn flywheel housing.
Key Features
- Genuine OEM Construction — Manufactured to the same dimensional and material tolerances as the original, ensuring the flywheel is properly enclosed and supported within the drivetrain.
- Direct-Fit Replacement — Engineered to bolt directly into the BLW-400SSW welder using the original mounting points, with no reworking or modification of surrounding components required.
- Confirmed BLW-400SSW Fitment — Verified for the Multiquip BLW-400SSW welder, taking the guesswork out of parts sourcing for this machine.
- Structural Integrity Under Load — The housing maintains correct alignment between the flywheel and engine block, protecting rotating components from misalignment stress during operation.
- Fuel System and Ignition Protection — A properly sealed flywheel housing shields internal rotating components from debris, moisture, and contamination that can accelerate wear and trigger ignition faults.
The flywheel housing is a structural enclosure that surrounds the flywheel and acts as the mating interface between the engine and the driven assembly. It maintains precise alignment of the flywheel relative to the crankshaft and protects the flywheel from external damage and contamination. A cracked or improperly seated housing can cause vibration, misalignment, and premature wear to the flywheel, starter, and surrounding drivetrain components.
