Question about Makita 4" GRINDER BRUSH KIT F/9501BZ 9514B 458-743200-0A

Open Question

There is a small rubber clip in my Makita 9514B that obviously holds a single wire to the brush holder assembly. How is this installed?

It looks like it should be on the white wire, but where on the brush holder? Where can I see an exploded view?

Replace brushes


In the middle of the housing set on both sides, there is a cap cover you have to pry off with a small screwdriver to get to the brush caps. Screw the brush caps off and remove the brushes (PN CB-430). If the brushes are stuck, pull on them until they come out. If the brush contacts/wires break off, you'll have to remove the armature and push the brushes through the brush holders. If the brush holders are damaged, replace the end bell, PN638448-2.

Replaced switch on my Makita 5007nb saw, still will not run.Brushes are good.


I don't mean to sound too patronising, but I get all sorts coming into my repair shop. Have you checked the continuity up to the switch, i.e through the plug and cable? Also, remove the brush caps but leave the brushes in place and check the continuity across the back of the brushes. There should be a circuit cross the motor, and if there isn't it is probably just that the brushes are sticking slightly due to sawdust. If this is ok, then remove the brushes and check continuity from the live wire (with the switch locked on) to one brush holder and then the other. You should only get a circuit too ne holder. The do the same with the neutral side. Again you should only get continuity to one holder (the opposite one to the licve circuit). If you don't get continuity both ways, and the switch is new, this would indicate an open circuit/loose connection on the field coil assembly. If the armature was faulty the machine would normally still run but with low power and excessive sparking.

I have a 1999 3,8L ford mustang my tester indecates the alt is overcharging,but the batt light is coming on but it goes off! is there anything i can do to besides replace the alt?


Your alternator-mounted voltage regulator has failed. Luckily, your voltage regulator is
replaceable separately from the alternator (most voltage regulators are integral to the alternator,
and cannot be separately serviced).

Note: this works for 3.8L cobra alternators/voltage regulators only - in the 4.6L model, the
voltage regulator is an integral component of the alternator.

1999 Ford Mustang Cobra -3.8L engine

3.8L Engines

1. Disconnect the negative battery cable.

2. Remove 4 Torx® head screws holding the voltage regulator to the alternator rear housing. Remove the regulator, with the brush and terminal holder attached.

Fig. 1. The regulator and brush/terminal holder are mounted on the backside of the alternator

Fig. 2. The regulator and brush/terminal holder are secured by 4 Torx® head machine screws

Fig. 3. Hold the regulator while removing the screws to prevent the regulator from dropping out and damaging the brushes

3. Hold the regulator in one hand and pry off the cap covering the A terminal screw head with a small prybar.

4. Remove 2 Torx® head screws retaining the regulator to the brush holder. Separate the regulator from the brush holder.



Fig. 4. Slide the regulator out-the brushes will move out of the holder

Fig. 5. The brush and terminal holder can be separated from the regulator once it is removed from the alternator

=========================================================
To install:

1. Install the brush holder on the regulator with 2 retaining screws. Tighten the screws to 25-35 inch lbs. (2.8-4.0 Nm).

2. Install the cap on the head of the A terminal screw.

3. Depress the brushes into the holder and hold the brushes in position by inserting a standard size paper clip, or equivalent tool, through both the location hole in the regulator and through the holes in the brushes.

Fig. 6. When installing the regulator, press the brushes back into the housing

archaeology_75.jpg


Fig. 7. Use a thin piece of soft material, like this plastic wire tie, to hold the brushes in position while replacing the regulator, or use a paper clip inserted in the hole

4. Install the regulator/brush holder assembly and remove the paper clip. Install the attaching screws and tighten to 20-30 inch lbs. (2.3-3.4 Nm).

5. Connect the negative battery cable.

Riccar 8000 Series Brush Won't Engage


Greetings from GoVacuum,

It sounds like you have a bad part called the Clutch Rubber Pad Holder Assembly on the inside of your roller brush. I believe that the problem you are having is that the roller brush does not spin, but the belt is properly installed and engaged, correct? This can only be something inside the clutch mechanism in the roller brush itself has gone bad. The easiest way to fix this is to purchase a new roller brush assembly, which can be purchased here; Riccar 8000 Series Roller Brush With Rug/Floor Switch. I realize that this is a rather expensive part at $43.00, but it may be worth it for you to avoid the aggravation of having to take apart the roller brush piece by piece. To test out this part, and verify that it has gone bad what you need to do is turn the vacuum upside down and remove the bottom plate. Then make sure the vacuum is in the Carpet setting on the Rug / Floor switch on the top of the vacuum. Now while the bottom plate is off, turn the vacuum cleaner on. Can you see the belt spinning on the brush? Is the brush roll itself not spinning? If the belt is spinning on the pulley, but the brush itself is not spinning, this indicates that it's bad.

If you decide that you'd rather just replace the rubber gasket inside of the roller brush, here's a detailed repair solution for you on how to replace this part;

Step 1: Remove the roller brush from the vacuum cleaner completely. If you need help with this step, please see my repair solution for the belt change on your model here; http://www.fixya.com/support/t4184186-replace_belt_riccar

Step 2: Once the roller brush has been removed, turn the brush on it's side, so the metal end that has 2 teeth protruding out is on top, and the end that has the rubber cap is downwards. Use a flat head screw driver to remove the clip on that outside of the brush;


7c5e20c.jpg
Step 3: Remove the clip on the outside of the brush with a screw driver, then remove the metal end cap from the brush. The entire roller brush is spring loaded, so you'll need to apply some downward force to these parts so they don't just shoot off. It's really the easiest if you lay out the pieces to the roller brush in the order that they were taken off, to make it easier when you are reinstalling these pieces. After removing the metal cap at the end, this is what you should see:

23dd8af.jpg
Step 4: There is a small plastic washer underneath of the metal cap. Remove the washer, and the plastic part underneath of the washer that has two teeth protruding outwards. This is how the brush should look after this step;


d940b1d.jpg

Step 5: After removing the plastic part with the teeth, the next part of the brush is the metal part which is called the Inside Metal Cam. The Inside metal cam is the part that the actuator arm for the rug / floor switch connects into. Remove the Inside Metal Cam from the brush. This is how it should look after this step;


fd04308.jpg
Step 6: The next part underneath of the Inside Metal Cam is called the Agitator Pulley Clutch. This is the part that the belt rides on. Remove the Agitator Pulley Clutch from the roller brush. This is how it should look after the Agitator Pulley Clutch has been removed;


f634050.jpg
Step 7: The next part that needs to be removed is called the Agitator Compression Spring which is used to spring load the entire roller brush. Simply slide this spring off the Agitator Shaft, and this is how it should look;


02b8973.jpg

Step 8: After the Agitator Compression Spring has been removed, turn the roller brush on the side, and remove the Agitator Shaft from the roller brush. This is done by simply pulling the other side of the brush end which is covered by a rubber boot. This will remove the long metal shaft which is sticking up. This is how it pulls out;


dec4f58.jpg
After the shaft has been removed, the other end of the brush should look like this;


0c192ff.jpg
Step 9: The next part that needs to be removed is probably the part that's worn out on your vacuum. The part is called the Clutch Rubber Pad Holder Assembly, Riccar Part Number C012-0400. The way the roller brush works is, when you move the Rug / Floor switch to Floors, the clutch (the parts that you just took apart) loosens up so that the belt is still turning, but the pulley that it spins on is not tight against the brush. When you select the switch to carpets, the clutch then tightens the pulley against the Clutch Rubber Pad Holder Assembly so the when the belt spins on the pulley, it's also now going to spin the brush. Over time this part gets heated up, and the rubber wears down to a point where the pulley will no longer stick to it, which causes the exact problem that you have, where the belt is installed correctly, but will not spin the brush. Simply use a flat head screw driver and pry directly on top of the brush strip, and remove the Clutch Rubber Pad Holder Assembly;

rsz_1riccar_repair-9(1).jpg This is how the part looks by itself; t1riccar_repair-14.jpg?732892 If you're interested in purchasing this part, you may contact your local Riccar dealer, or we can also supply you this part. Once again this part is called the Clutch Rubber Pad Holder Assembly, Riccar part number C012-0400. Please just email me at chris.jones@govacuum.com for pricing on this part if you need it.

A-200 mixer brush carrier orientation.


Hi. I can't help you with your first question...But I can help with your brushes problem. Unplug the mixer With the two inspection plates removed at the commutator end loosen the two screws of the brush holder which are above and below the motor bearing cover, they're the only larger screws now visible. Note the markings on the brush holder on the bottom right side where you removed the inspection plate. Rotate the brush holder to the other mark. Set the brush holder screws. Plug in the power. and start the motor. It should now be turning in the proper direction, if not, make small adjustments by loosening the set screws, and moving the brushes until it starts to your satisfaction. Be sure that the set screws are tightened when you're done. If you need further assistance, post a clarification.

I have the same spec. mixer as you do.

If this solution has assisted you, please rate it. Good luck! ricardok45

Why does my dw831 grinder keep tripping circuit breakers?


try checking the brushes.

to do this: remove the 2 small covers on the left and right side of the tool and push aside the coil spring holding in the brush. the brush should freely pull out of the holder.

when you have the covers off, look for charring or melting. and after the brushes are out, rotate the arbor to move the armature inside and look to make sure it's not charred.

if that doesnt help, take apart the handle and look for melted or exposed wire. dewalt likes to pack the wires in tight among the screws and sometimes the normal vibration of the tool will cause a screw to cut into a wire and short the wire.

new brushes and holders (if melted) are usually around 20 dollars US

How to release new carbon brushes in their holder


All carbon brushes have an electric wire attatched to them, that needs to be gently praised off (make sure the machine is unplugged from electrical outlet), then using a flat headed screw driver, push in the clip that is holding the brush in place and at the same time gently pull the carbon brush up.

To replace the brush, simply push it back into its slot (but gently and carefully because it can snap) until you hear a click then replace the electric wire.

If you have left the rubber band on the brush when you inserted it back into it's holder, simply cut the band at the top and very gently pull it up until it is removed.
