Question: Spiral Bevel Gear

How do you remove the bevel spiral gear?

Question: Makita 9227c Dead?

763871

I have a Makita 9227c sander/polisher that has lived a long life of wet and dry concrete polishing that recently seems to have kicked the bucket. When I try to use it, it just whines/hums and doesn't move. Any thoughts on what might be the issue?

Reply: Makita 9227c Dead?

UtahAV

My first guess would be a bad armature. If there is some arcing and smoke or smell associated with the noise then I would be certain of it. If it is the armature you will want to disassemble the tool and inspect for additional damage to the field, housings and brush holders. These other parts are often damaged by the armature when it fails. I know how hard concrete work is on tools. My suggestion if the armature failed is to replace the tool.

I hope this helps!

Question: Variable Speed Control

What item do I replace to correct the variable speed control?
Unit runs fine at full speed but is inconsistent at slower rpms?

Question: Extension For The Buffer

Bryan

I work in the boating world and can't find an extension for the buffer pads that I use. No store holds this part and I know that the part is out there. It has a Female end and a male end; one end to goes on the buffer and the other for the pad to screw on.

WJA

Hi Bryan,

I checked with Makita and they do not supply a extension for their polishers. You might try some distributors of automotive detailing polishers and see if they can help you.

Good luck,
WJA

Question: Makita 9227c Question

Glen

I am trying to replace the spiral gear on my polisher. How do I get the old one off?

Question: Makita 9227c Question

scott

When I pull the trigger it starts but stutters like it is being turned on and off really fast. The trigger only works when pulled all the way in. I'm thinking the trigger is bad or the speed controller?

Question: Test Armature

josh

How do I test the armature on this grinder polisher?

Reply: Test Armature

Mark

Hi Josh,

A bad armature will usually let itself be known with lots of sparks and some smoke from through the vent holes near the rear handle. If you tool has not done this and you still suspect a bad armature you will need to remove the armature and take it to a good repair shop. The shop should have some specialized tools they will use to test the armature. One test will put very high voltage through the armature. That will help isolate an open short in the windings. Another test will create a magnetic field around the armature and will find any shorts on the commutator.

I hope this helps with your repair!

Question: Makita 9227C Rotary Buffer

Bondo

I have a used Makita Rotary Polisher.
Speed control does not seem to be responding consistantly.
Full rpms work but the lower rpm, are inconsistant, they work and then they don't work.
I"m am going to toss in a new set of brushes, and a new cord and cord protector, but I am not sure what controls the variable speed?
Any body have experience with these buffers?
Thanks in advance for the reply!

Reply: Makita 9227C Rotary Buffer

Tinkerdave

Hi, you have most likely have a bad controller #681801-1 and/or Magnet sleeve # 688110-9. Check the Magnet sleeve first and make sure it tight on the shaft.This is generally what goes wrong with the Makita polishers when they start acting like that. If you replace the controller also replace the magnet sleeve also.Hope this helps.Good luck.

i'm trying to replace the spiral bevel gear on my makita 9227cy sander/polisher. i can't see how to remove the old one from the spindle assembly.. does anyone know how?

Reply: How To Remove Bevel Gear On Maki...

cmoorejack

Hey bptool,
It looks like a pressed on fit and it is best to use an hydraulic or arbor press to remove..pullers and a torch to heat the gear is another option..ugh :( if you have a local repair shop nearby they shouldn't charge too much to change out for you..it is also recommended that both gear components are replaced for maximum results..sorry.. I wish I had a better solution for you...
hope this helps..?

Question: 9227 Help

makita

I have a 9227cy 7 inch polisher that I want to change pad from 7 inch to 5 inch to polish concrete with. Can someone recommend a 5 inch pad? How do you get the 7 inch pad off? I will be using wet diamond discs.
Thanks, Jim

Reply: 9227 Help

UtahAV

Hi Jim,

There is a milled spot on the spindle, just above the pad, that will accept a wrench. Lock the spindle with a wrench and then you can remove the pad with a counterclockwise rotation.

I am not sure what type of abrasive you had planned to use for polishing concrete but I thought I would mention that we do offer diamond grinding cups here at ereplacementparts.com You can find the cups at the following link...

great tool. mounted an 8 " foam rubber "floater" disc for use as a non-digging sander. use stick on paper-cut my own discs from regular sheets- automotive adhesive or contact cement.
