The DEWALT 9r213407 is a ring retainer designed to secure internal components within compatible DEWALT power tools. Ring retainers hold shafts, bearings, or other rotating assemblies in precise axial position, preventing movement that could cause premature wear or mechanical failure. This is a genuine DEWALT replacement part intended for technicians and repair shops servicing DEWALT power tools. Sourcing the correct retainer ring ensures proper fitment and restores the tool to factory-specified operating tolerances.
The 9r213407 ring retainer is used during power tool repair and rebuild procedures where the original retaining ring has become worn, deformed, or lost during disassembly. It is suited for shop-based repair technicians and field service professionals working on DEWALT power tool platforms. Installation typically occurs during a broader service procedure rather than as a standalone replacement.
Designed as an OEM-style replacement ring retainer for compatible DEWALT power tools. Confirm the part number against the specific tool model service diagram before ordering to ensure correct fitment.
Installation of this ring retainer should be performed by a qualified tool repair technician. Disconnect and de-energize the tool completely before disassembly. Use appropriate snap ring pliers or retaining ring installation tools to seat the retainer without distorting it. Refer to the manufacturer service documentation for assembly sequence and proper seating depth.
