Something wrong with the armature

I have a makita 5" angle grinder model 9005b, I think the armature shorted out. Can anyone tell me how to remove the armature for inspection?

    hi, You are probably not going to get a good answer to your question. 1. What makes you think it is the armature(which is probably the last thing that would go wrong) 2. What if it is? You have bearings to contend with, repairs on an armature are virtually impossible for a diy guy, and if you decided to replace it the cost vs a new one is questionable as well as the fact they are spin tested for fit in each unit.

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

Buy the new brushes from the manufacturer. You already have the old ones out - put the new ones in the same way you took the old ones out.

yes there is, go to "makitausa.com" and with your model number you can download a breakdown for these tools. There is a plastic cap that snaps on the pin, you will have to replace the cap also but after removing the gear housing you pry the cap off and them remove the lock pin. Clean the area on top before reinstalling. Let me know if you need more assistance and I would need the model numbers so I can give you part number.

Angle grinder eats carbon brushes


Yes, the rock dust is what's destroying your brushes and armatures. It gets sucked into the rear vent slots and gets to those parts and eats them away quickly. I don't know of any vacuum systems make by Makita but there are some companies that make them for their systems. Blastrac is one that comes to mind but they can be real expensive systems. I don't know of any grinders with sealed brush/armature systems, they have too much heat to disipate. To make your Makita grinders last longer make sure you are cutting with the side of the blade that directs the dust away from the case and try to have a strong airflow blowing the dust away from the grinder to minimize the dust taken in at the back of the grinder.

you can try going to Makitatools.com and downloading a breakdown for this tool. If it arcing badly at brushes there could be a wiring problem or damage to the armature, check the wiring first and also the wheel spinning off might mean that you are running in reverse. did you take the field out of it and if so it might be in 180 degrees out. Let me know

Armature problems


Unplug tool and then remove the brush caps and brushes, at the front of the tool are 4 screws that need to be removed after removing them you might have to pry the gearcase from the motor housing and then it should just pull out if there is no problems with the field having been hot and melted. Let me know if you need further assistance

Can't get grinder to turn on. Checked brushes, cord, trigger/switch. Any suggestions?


Did you check continuity to the field/brush holders. They have a garter spring that sometimes became overheated and broke. It seems like you have done everything else. Let me know
