MAKITA 9555HN ANGLE GRINDER, 710W. REPLACEMENT OF GEARBOX BEARINGS.
Angle grinders: Makita 9554HN, 9555HN, 9557HN/HNK/HNZ, 9558HN/HNK/HNZ. Time has shown that this series is more suited to industrial power tools than household use, due to its incredible reliability and popularity among its competitors. However, the gearbox bearings are the first to fail after long-term use. Due to the fact that the entire load of cutting and other wheels falls on the main bearing 6201DW, slight play in the gearbox shaft axis initially appears, then it increases and then intensive wear of the teeth of the drive and driven gears begins. Using such a tool is difficult, with increased vibration, accelerated wear of the cutting wheels, and chipping of the abrasive. All you need to do is replace both bearings and the gearbox at the same time, and you'll have a perfectly functional grinder with a fairly long service life. The cord, the button, and the brushes are just consumables, and they can be replaced indefinitely.
