The DEWALT 389501-01 is an OEM-authorized replacement spring designed to restore proper mechanical function in compatible power tools. Springs of this type maintain tension, return mechanisms to rest position, or retain components under load depending on the tool assembly. This part is manufactured in the United States and meets original equipment specifications. It is the correct service replacement for worn, broken, or missing springs in applicable tool models. Service technicians and authorized repair shops handling power tool maintenance will find this part matches the original factory component exactly.
This spring is intended for use in various Black and Decker tool models where the original spring has failed or requires replacement during a repair service. It is suited for bench repair scenarios where disassembly of the tool is required to access internal spring mechanisms. The compact dimensions make it applicable across a range of tool housings without modification.
Fits various Black and Decker models as specified by the OEM. Consult the tool model's parts diagram or the manufacturer's service documentation to confirm fitment before ordering.
Installation should be performed by a qualified power tool service technician or authorized repair facility. Disconnect the tool from all power sources and remove the battery pack before beginning any disassembly. Refer to the manufacturer's service manual for the specific tool model to locate the spring and follow the correct reassembly sequence. Retain all hardware removed during disassembly to ensure complete reassembly.
