Key Features
- Genuine OEM Construction — Manufactured to the same dimensional and material tolerances as the original collar, maintaining the precise fit and retention characteristics the machine was engineered around.
- Direct-Fit Replacement — Installs in the same position and orientation as the factory part, with no machining or modification to mounting surfaces required.
- Broad Welder Compatibility — Confirmed fitment across DLW300, DLW330, DLW400, DLW500, and DAW500 series Multiquip welders, covering both diesel light welder and diesel arc welder platforms.
- Structural Integrity Where It Counts — A properly functioning collar maintains component alignment and prevents axial movement; a worn or missing collar can lead to misalignment, accelerated wear on adjacent parts, and unplanned service intervals.
- Verified Multiquip Part Number — Ordering by OEM part number 0821800014 eliminates guesswork and reduces the risk of receiving an incompatible component.
A collar is a mechanical retention and alignment component used to secure a shaft, sleeve, or rotating assembly in its correct axial position within a machine. In welder and generator-style equipment, collars are commonly found in drive train, fan, and power takeoff assemblies where they prevent unwanted lateral or axial movement of rotating components. When a collar wears, cracks, or becomes loose, the components it supports can shift out of alignment, leading to vibration, uneven wear on bearings or seals, and potential damage to surrounding parts if left unaddressed.
