The PRO-SOURCE 5520002089PRO is a rebuild kit designed for 4-inch angle disc grinders. This kit provides the internal components needed to restore a worn or damaged angle grinder to proper working condition, extending the service life of the tool and reducing the need for full replacement. It is appropriate for use by maintenance technicians, electricians, and other trade professionals who rely on angle grinders for cutting, grinding, and surface preparation tasks. The kit is sized specifically for 4-inch diameter angle grinder applications and ships as a single-unit package.
This rebuild kit is intended for use in maintenance and repair settings where tool downtime needs to be minimized. It is suited for shop environments, job sites, and field service scenarios where keeping angle grinders operational is a priority. The kit is a direct-fit solution for restoring a grinder rather than sourcing individual components separately.
Compatible with the 4-inch Angle Grinder Cut Off Tool model 5520003050JP. Designed as an OEM-style rebuild kit for 4-inch angle disc grinder applications.
Installation should be performed by a qualified technician familiar with power tool disassembly and reassembly procedures. Disconnect and de-energize the tool completely before beginning any rebuild work. Follow the tool manufacturer's service documentation for disassembly sequence and component torque guidance. Proper reassembly and functional testing should be completed before returning the tool to service.
