The Multiquip 3311612004 Coupling Hub Washer is a genuine OEM component designed for BLW-400SSW and TLG12SPX series equipment. Sourced directly from Multiquip, this washer meets the original engineering tolerances specified for these machines. Correct fitment is confirmed for both the BLW-400SSW and TLG12SPX, making this a straightforward, part-number-verified replacement when servicing the coupling assembly.
Key Features
- Genuine OEM Construction — Manufactured to the exact material grade and dimensional spec of the original washer, ensuring proper load distribution across the coupling hub interface.
- Direct Drop-In Replacement — Seats into the coupling hub assembly the same way as the original, requiring no reworking of adjacent hardware or mating surfaces.
- Confirmed Fitment — Verified for BLW-400SSW and TLG12SPX models; use part number 3311612004 to cross-reference before ordering.
- Protects Coupling Integrity — A properly functioning coupling hub washer maintains even clamping force across the hub, preventing fretting, loosening, and premature wear of surrounding drive components.
- Electrical and Drive System Safety — In generator and welder applications, a failed or missing coupling washer can allow drivetrain misalignment that stresses the alternator shaft and disrupts output stability, making this a critical replacement item.
The coupling hub washer sits between mating surfaces within the drive coupling assembly, distributing clamping load evenly and preventing metal-to-metal contact that would cause wear or fretting corrosion. In generator and welder applications like the BLW-400SSW and TLG12SPX, the coupling connects the engine to the alternator, and even minor play introduced by a worn or missing washer can translate into vibration, shaft stress, and inconsistent power output. Replacing this washer at the first sign of wear keeps the coupling assembly tight and the drivetrain running smoothly.
