SOURCE: 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

Makita bhp454 overheated, not turning clockwise.


It is very common for the armature to overheat and melt down.

Open it up and inspect the armature, it will be very obvious it is burnt.
If it is the case, replace the brushes (#16) and the armature(#14)

Makita grinder keeps tripping circut breaker


FIRST OF ALL !!
Control where the tool is used first for undervoltage on the mains supply group.

If it is everywhere a problem FIRST replace the circuit breaker.

After that control all connectors last check interference suppression capacitor.
If all are controled , relace armature or electric field or both.

How to remove field coil from makita hr3000c drill/breaker


Here is a parts breakdown for your drill. Of course the armature has to be removed first. There are two screws holding the field. It should just push out at this point. If not, the housing may be melted to it. Good luck with that. https://www.ereplacementparts.com/makita-hr3000c-rotary-hammer-parts-c-97_380_507.html

Brushes arcing


Brushes arc for several reasons. If the spring over heated and lost its tension or the copper line from the brush to the cap broke/burnt off or the brush wore down too far to be pressed on the armature properly. The replacement brushes you need are Makita part number CB-124. If you still have exessive sparking after replacing the brushes you may have a bad commutator on the armature. The only way to fix that is to replace the armature, Makita part number 512831-0.

Makita 2012nb replacement motor


I have a service center for Makita tools and the only way to fix or replace the motor is to buy the parts you need, in this case the armature (PN 516811-8) and field assembly (PN 526101-1). You can go to a site like www.ereplacementparts.com or any other aftermarket site to get them or try finding a local Makita repair center and find out how much it would cost to get the parts through them.

Gears seem to be skipping. which of the 2 gears is most likely to wear? the one on the armature? or the big disk one?


If one gear is damaged it is causing damaging to the other, whether you can see it or not. If you have teeth that are skipping, the gear with bad teeth will wear out the teeth on the other gear. You should always replace both gears. On your polisher, the small drive gear isn't on the armature, it's part of the armature (Makita part number 515266-4) and that's a $90 to $110 part to replace. The spiral bevel gear (Makita part number 227455-6) is $40 to $45. You can replace one or the other but the gear you leave in will only wear out the new one.

you have a armature problem I would think, look into the brush tube and try and spin the armature and look for discoloration on the commutator bars.
