The DEWALT 103998 is a lower left bumper designed as a replacement component for DEWALT power tools. Bumpers serve as protective guards and contact surfaces that absorb impact, reduce vibration transfer, and protect both the tool body and work surface during operation. This part is installed by technicians and repair professionals servicing DEWALT power tools where the original lower bumper has worn, cracked, or been damaged. It is a direct OEM-style replacement intended to restore the tool to proper operating condition.
This bumper is suited for use in professional tool repair and maintenance scenarios. It fits within a specific DEWALT tool platform, referenced internally as the 134 series based on supplier data. Repair technicians working on compatible DEWALT equipment will find this part a straightforward drop-in replacement for the original lower left bumper assembly.
Designed as an OEM-style replacement lower bumper for compatible DEWALT power tools in the 134 series platform. Consult the DEWALT parts diagram for your specific model to confirm fitment before ordering.
Installation should be performed by a qualified tool repair technician familiar with DEWALT power tool disassembly procedures. Disconnect and fully power down the tool, removing the battery pack or unplugging from any power source before beginning service. Use manufacturer-recommended hand tools and follow the applicable parts diagram for correct positioning of the bumper. Inspect surrounding components for wear before reassembly.
