Hi,

My sander works alright but seems to spin too fast and has excessive vibrations while running. I've taken it apart and the bearing box seems to rattle around loosely. I can hear it clanging against the fan and it translates into excessive play in the sander pad. Any tips on how to repair? Thanks.

Hi,
As long as the fan is still in excellent condition then replace everything between the fan and the pad.This is all high wear items and should always be replace when the unit is torn down.Hope that helps.Good Luck.

makita orbital sander 5010/runs when turned on but pressured it stops movement?

Hi fiveyes55,
I'm assume you have the "B" model?. If so I would check the Fig. 20 211236-8 Ball Bearing 6002DDW.A frozen bearing would cause that exact problem.Hope that helps.Good luck.

Question: Slow Spins

Sander started spinning slowly recently. Brake ring looks OK. When I disassembled, several pieces of an "O" ring fell out; approx. 3 inch diameter. Probably fits in skirt set. Don't see this part on parts list. Suggestions?

Hello gedelliott,

The o-ring you are looking for is used on a couple Makita Sanders. It may be the part you are looking for. It is part number 213755-0.

makita model bo5010, part 743081-8 Sander Pad - Hook & Loop

This part, the sander pad, is made up of two parts: a hard plastic disc (that screws into the sander) and a foam rubber pad that connects to the hard plastic disc with 8 foam rubber 'pegs'. The foam rubber peg connection to the hard plastic is weak material; and it broke on mine. I'm set to get a replacement part; but I'm thinking the foam pegs are so weak I'd rather get a replacement part that's all hard plastic & no foam rubber. Does this exit & where can I purchase it? Or otherwise what can you tell me about this issue?

I have a similar makita sander it uses many of the same parts it is the model 5021K just a different body with speed control.

I never had the pad off but they do have the self stick pad whether it's the same foam or not I can't tell. I thought the pad was at least glued the the plastic disk.

Question: Replacing The Sander Pad

I just replaced my sander pad, but when I start it up it sounds very strained and then dies. If I take it off, it works fine. If I loosen the screws, it sounds terrible. Help!

Reply: Replacing The Sander Pad

Tinkerdave

Hi flikitysplit,
Two of the high stress parts on that sander are 211236-8 Ball Bearing 6002DDW and 210020-8 and Ball Bearing 6000DDU.Take your pad off and see if the 316834-4 Bearing Box Cove spins freely.Also check that your armature bearings are spinning smooth and free by spinning the fan. You should also replace your 421866-9 Brake Ring any time you replace your pad.Hope this helps.Good luck.

same problem-- when I screw new pad on it will not even turn-- I have spent $30 on new pad & $6.60 on new break ring-- should have thrown it away & bought new one-- maybe dewalt--
My Makita bo5010 sander goes into a circular spin when I put it on the surface that I want to sand. It never used to do this. What might I do to prevent the sander from spinning?

Hi Bruce,

My sander just started doing this also. When I tore it apart I found that the lower bearing had frozen up and the brake ring is shot. These are items 17 & 20 on the parts diagram. They are easy to get to, just remove the three screws on the hook pad and remove. Then remove the brake ring (just snaps in). Remove the screw & washer holding on the bearing.

Question: Makita BO5010

many hours of hard use on this sander. When I go to lower sander onto wood It grabs the wood and digs into wood. I almost ruined a veneer walnut door when i went to sand the surface and the sander grabbed and gouged the wood. Went through the thin layer of walnut before i could gain control of the sander. Never used to do this. Any ideas?

What is the difference between sander pad 403A and 403B for the Makita hand sander? The illustration of parts only shows 403.

Thank you.
Mark
Reply: Parts

Mark

Hi Sue,

The 403A is the pad to use with the Hook & Loop, or Velcro type paper. The 403B uses PSA paper. That is the type that sticks on to the pad with adhesive.

I hope this helps!

Question: Spins

My random orbit sander spins out of control (very fast) when not under load.
Mark
Reply: Spins

Mark

Hi Chris,

It sounds like the brake ring on your sander has gone out. The brake ring acts like a clutch to control the pad speed when there is no load. When it wears out your sander will spin out of control. The brake ring is part # 421866-9 and is available from http://www.ereplacementparts.com.

Good luck with your repair!

Question: Replace Makita BO5010 Brushes?

mlhenneman

I need to replace the brushes on my Makita orbital sander. I have no problem taking the thing apart and seeing them, but does anyone have any tips on getting them in correctly? I just replaced the switch that was broken and I think I messed up the brushes trying to get them out of the way to put the sander back together, because it goes on now but just hums without spinning. It's old enough that they probably needed to be replaced anyway, but it seems a rather delicate operation, and I would like to not mess them up again trying to get them in.

Thanks for any advice.

Dag. Your problem is the lower bearing behind the sander pad. Its froze up. part # 211236-8. Its # 20 on the diagram. When you raise the tool its spinning on the armature bearings. when you place it on your project. It stops the tool because the pad can no longer spin. hope this helps. Trust me its the problem. They have Seven in stock at eReplacement.

Same issues as with the other customer, Hook pad short life, bad switch, etc. Came to site to look for replacement pad, and now must decide if it is worth it.

I had the same problem with the hook and loop, but switched to adhesive and have had good luck. I think it was worth the 25 or so bucks. I did just recently have a bearing go out, but found another one at a bearing store in my town for $8. Beats spending another $80 for a new sander. Why they keep making hook and loop sander pads I will never know, they are crap.

Hook & Loop sanding pads offer many benefits to the woodworker. They offer the ability to change sanding grits quickly. The user may remove and then reattach a sandpaper disc allowing for maximum use and reducing the cost of sandpaper.

The Hook & Loop sandpaper system consists of a sanding pad with fine plastic hooks, which is attached to the sander, and sandpaper discs, which have a looped fabric backing. The loops on the fabric backing are held by the hooks on the sanding pad.

Hook & Loop sanding pads will last through many hundreds of sandpaper discs with proper use. The most common cause of a Hook & Loop pad to wear out prematurely is excessive pressure being applied to the sanding pad. Only enough pressure should be applied to the sander to keep it on the workpiece and to guide the sander in the desired sanding pattern. Excessive pressure creates heat build up in the sanding pad which will quickly damage or even melt the tiny plastic hooks. Once the hooks are damaged they will no longer hold the fabric backing on the sandpaper effectively and the pad will need to be replaced. When excessive pressure is applied it slows or even stops the random action of the sander causing a large increase in swirl marks left on the workpiece.

Best results and fastest sanding will be achieved by using light sanding pressure and a proper selection of sandpaper grits. Start with the coarsest grit needed to quickly remove any rough wood surfaces or uneven glue joints. Once the surface has been smoothed and leveled you can move through the sanding grits to the desired finish. Never skip more than one sanding grit at a time. Skipping grits requires additional time and effort to remove the scratches left by the previous grit. The finest grit needed depends on the type of finish the project will receive. If a film finish, such as polyurethane or lacquer is to be used then 180 or 220 grit will be sufficient. Film finishes can have problems adhering to surfaces sanded finer than 220 grit. If the project is to receive an oil finish then a 400 or even 600 grit finish may be desired.

Mark's reply makes sense to me. I used my 5010 for a few dozen hours and I often pressed hard on difficult spots. When my hook and loop pad gave out yesterday, I wondered why. Now I know. $25 or less doesn't seem like too much for the use I got. It's the only repair I have had.
