Thanks for making this video. Very helpful and I just bought some of your wheels on Etsy. Cheers!

Hello, do you know what size the pin connections on the power cord are? I. Trying to repair the cord. It was cut like a foot from the robot.

Just ordered. Thanks 👍

Great video! One question: how much play can the burr shaft have? Mine does wobble quite a bit sideways and the inner burr can move up and down a bit. Is this normal?

How tight should the bottom nut be on the shaft? Finger tight or not going to come off ever again tight!

Hey! It says your shop is currently closed, would you be able to upload the stl somewhere?

So you don’t have to remove the screws inside of the axels prior to removing the axels?

I followed the video and my 2 end gears were trash. Just ordered. Thanks

Great video. One question... For the limiter/clutch shaft assembly, is there any specific torque or you just screw it hand tightened? Mine gets loose every week, lol

Great Video, after watching this I just took mine apart and found the same two gears stripped just the same. I ordered four replacement gears from you since I might as well replace all four while its apart- Thanks Again!

I have a newer Polaris, VRX 4WD, need all new gears and bushings. Do you make those?

$150 for the gear for a $200 grinder? Lol

Thank you for the informative and meticulous video. Very thorough with great instructions and tips. Looks like I have to disassemble mine. I’m witnessing it struggle to move with the rollers appearing to stick and pause on the pool floor until I receive the two flash error code on the computer box. You can expect an order if I discover the gears need replacement. Thanx again…

Absolutely fantastic video with the great option to buy your printed gear. Truly outstanding. Thankyou !

I took mine apart and all the gears are good. The robot just sits on the bottom with the propeller running. Do you think the drive motor is bad?

I followed your video and when I open up the track it only had 3 gears. Do you know why that maybe? I have used this machine for over 2 years, never had it apart, and never had issues with it running on the 3 gears.

Great video and very informative. I Just needed some clarification on one part of the video. When you were inserting the small gear shaft into the gearbox, you demonstrated that there was a short end and a long end and that the short end goes down first into the black box with the long portion facing upward. However, in the video, you inserted the long portion of the shaft first with the short portion facing up. (between 19:03-19:10) I did order your replacement gear and looking forward to repairing my machine. Thank you so much for your product and your video.

Thank you so much, man. I fixed my grinder expending only 10 bucks

Is the tip of the Drive Shaft stepped down or WORN ?

Cannot stress enough how helpful this video was. I stripped the machine and bought your part because the teeth on mine were *slightly* torn. After replacing it I quickly learned that the problem was actually on the other gear. The plastic holes that support the metal balls and strings has broken off so the balls always come off their socket and my grinder spins freely. Any chance you also sell the replacement for the bigger part with the shaft?

Could not find a screwdriver thin and long enough to remove 2nd set of 4 screws. Had to return the gears back to makeSURFmake. He was very easy to deal with. He suggested a really long screwdriver from HarborFrieght, but I had already sent the grinder back to Breville for a repair estimate.

Great video, thanks. I came across it only after taking apart my BBE grinder and finding the striped gear teeth.. Do you know what the diameter is of the ball bearings? I lost one when disassembling to troubleshoot. Also it’s worth noting that the nut holding the slip clutch assembly has red Loctite on it (at least for my machine). It’d likely need that again if it was unscrewed. I’m also wondering if having it slightly less tight would help it disengage when it’s supposed to. I wouldn’t be surprised if differences in torquing that screw between machines is what causes some to fail.

Hi. I have stripped down, replaced the gear, checked the motor spindle - all ok, checked the white wheels, they move freely. But when i connect the two up the burr will not move. It is stuck solid. Can't figure out why this won't turn manually. I don't want to try with the motor as it will probably strip the new wheel out again. Any thoughts?

the center cylinder in the white gear is really loose in my expresso machine, the stucture of the grind motor is almost the same as yours ( I think), When I tried to deep clean the grinder, the entire center cyilder just came off earily ( to my understanding it should never come off when you are just removing the inner burr), Do you have any recommendation how to fix it? Thank you so much! your video is the only one I have found so far would go over all the gear in depth !

Thanks for the great vid and going to so much trouble. I’ll tackle the tear down tomorrow and check that gear.

Thanks for this. On the final pro tip, you can also super glue the washers to the screws instead.

once i open gear only 5 springs comes out with balls. are we sure that they are is 6 springs?

I've learnt a very important lesson - don't buy grinders with cheap plastic gears 😅. Mine survived almost 5 years, which is ok I guess. But this time I'll get a better one without a bunch of bs smart features and simpler mechanisms.

The sales site seems not to be functioning. Message says, “429 too many requests.”

Thank you for helping, not sure if my reply going through, it is plastic piece about 3/4 x 1/8 x 1/16 inch has a small notch to one end, I uploaded a video of it do better describe it to my RUclips, studio.ruclips.net/user/video7ui1b_OwQaE/edit . thx.

Nice video I bought the replacement Grinder Gear, but during taking it apart small plastic piece fell out I can not find out where it came from. I tried to look at diagrams on line with no success. any help will appreciated.

Saw you fly over this past weekend. I said to my self i bet he sees so many sharks right beside us. i was right lol

very impressive. this is something that I know I would pay for. Great job.

Great video! My issue was that two bearings in the other gear had gotten misaligned, resetting that shaft helped me in case someone else has the same issue.

cara, obrigado! excelente vídeo. Procurei alguns vídeos aqui no Brasil, mas não encontrei nada parecido como esse, ótimo tutorial . man thanks! excellent video. I looked for some videos here in Brazil, but I didn't find anything like this, great tutorial

Hi could you possibly tell me what size those 2 flat washer were…I seem to have lost one.

I need one

wow, thank you so much! ordered your part and worked like a charm. extremely detailed video made it easy too!

My grinder makes the big clank sound. Gear is missing a few teeth but what causes the loud clank?

Can you sell the 3D file to print the gear on my own?

Cool idea. I will look into it. The grind setting mechanism is pretty well integrated across the machine so getting more precision would likely require some significant mods. In the meantime, have you tried adjusting the setting on the burr holder itself to operate in a finer range?

Nice job! Can you design something to get in between grind sizes for espresso? I think there is a real demand for that. One weakness of this grinder is large gap between grind sizes for espresso

@makeSURFmake Very cool. Parts list available?

Fantastic video to keep your grinder going again!

This is awesome build. Do you have a part list the actuators and controller you used for your lift system?

Nice setup! I have some questions! Do you know the dimensions of the square tubing that you used for the actuators? Also did you use two separate control boxes for the actuators? I have been thinking of doing this for a while now and you are the first DIY version I have seen that makes the most sense. And do you find that your cap moves around on bumpy roads since you got that play at the top ?

Awesome setup and video. Nicely done!

Nicely done. And light weight. A bit high tech for me though.
