SOURCE: I don't know how to change the grinding blade on

There is a nut that you release from the middle of the grinder wheel, (grinder blade)
This nut is flat and has four holes in it.

You will see you are providing a spanner wrench to remove this nut. The wrenches' actual name is Lock Nut Wrench. It has a U shaped end with two pins sticking out. On on each side of the U shape.

The pins are inserted into the holes in the flat lock nut, located in the middle of the grinding wheel. The wrench is laid flat against the grinding wheel, with the two pins of the wrench going into any two holes of the nut.

At the top of the Makita grinder you will see a Black button. The button is pushed down to keep the grinding wheel from spinning. Holds the grinding wheel in place, as you turn the lock nut loose. When you release the button, a spring inside pushes the button back up out of the way.

As you view the Makita grinder, Release Button towards the Back, grinding wheel towards you, the nut is turned to the LEFT, to loosen. It is a Left threaded nut.

The grinding wheel spins to the Right. Using a left threaded nut insures that the nut will stay tight, due to the direction the grinding wheel spins.

How to change the big drive gearMakita angle grinder 9557 PB


Remove the bearing, retaining ring and wave washer on top of the spindle. Now you need a press to push the spindle out of the gear and bearing case. There is a very small woodruff key in the spindle, be careful not to lose that. Do not try to drive (hammer) the spindle out, if you mushroom the end even the smallest amount, you'll have to replace the spindle because you'll never get the bearing back on.

My Makita "GA9020 9"" Angle Grinder has started to vibrate really bad.there seems to be play in the spindal.its used for floor sanding.i was thinking maybe bottom bearing,but just guessing any ideas thanks


Vibrations and excessive play could be caused by one of two or both bearings in the gear housing or the spiral bevel gears. Armature bearings can cause vibrations but usually don't show up as play at the spindle. Also, if the vibration is really bad, you could have several fan blades broke off one side of the armature fan throwing off the balance.

Replacing the gear on makita angle grinder


Are you replacing both gears? The armature gear (pinion) is usually held on with a nut or else is pressed on. The spindle gear is also pressed on. Most spindle gears will come as an assembly with the gear and spindle and housing all together.

If yours doesn't, then the spindle will need to be pressed out of the housing, and then the gear pressed off of the spindle. (Always replace the grease as well when replacing gears.)

I havebeen using a makita 9527 pb 4.5" angle grinder and all the sudden the grinder had troubles working all the time at first it took a little shaking to start up then hitting against a hard surface...


There are various causes of failure but the checks should be carried out in this order, you will need a continuity meter or multimeter to trace continuity from the plug to the switch in the grinder:

If plug is rewireable check for loose screws at plug pin terminals, loose fuses etc.
Wires in power flex breaking, usually at plug or where flex enters machine.Check the continuity from each pin of the plug to the switch in the grinder
Faulty on / off switch or loose spade terminals on switches.
Worn out brushes.
Armature or field coils of motor going open circuit.

Something wrong with the armature


If the armature is shot, it will spark a lot where the brushes are touching the armature comutator. To remove the armature:1 Remove brushes. 2 Remove 4 screws holding the gear box. 3 Pull away gear box from the body. The armature may come with the gear box or not, it's only pushed in, so you should have no problem to disassemble it. If the armature stay in the grinder, use two skrew drivers to pray it out. You may not see anythink wrong with it, but it may be no good . That's Makita special, they don't make it good as they used to. The price for new grinder is about $130, for armature $65. field $40
