Makita 688117-5 — Magnet Sleeve (original Makita replacement). This compact cylindrical sleeve locates over the motor/magnet assembly and restores the correct spacing and alignment of the magnetic/retainer components.
The sleeve sits between the stop ring and the wave/flat washer to hold the magnet/retainer stack concentric and to reduce axial play that can cause vibration or premature wear.
Fits a range of Makita tools — examples shown in official parts breakdowns include GD0800C / GD0810C / GD0811C angle grinders, GA5040C / GA5041C / GA5090 grinders, BO6050J / BO6040 sanders), and compact router/hand-tool assemblies such as RT0700C / 3708FC.
