Just want to say a BIG THANKS! 15 EUR for 2 new ball bearings, and it works perfectly now, no noise anymore. You made me save 500+ for a new rotor only. So, thanks again! Model: Renson Healthbox 2.0

Thank you! My unit (Vasco 450D) started to make lots of noise after 3 years of use, nobody (even manufacturer) said something could be done except replacing the fans (>500EUR), now it cost me 8EUR in bearings (and 20EUR for the tool to extract them properly). Bearings used: 608zz. Quite so far, hopefully it stays that way. PS: Not that well filmed, the important parts are of screen... Recommend this: th-cam.com/video/M1O--y3kg0o/w-d-xo.html

Hat bestens geklappt. Vielen Dank!

Very cool idea if you are invested into the Parkside 20v battery system

Can I use the 4ah version to jump it?

Vielen Dank, tolle Anleitung. Konnte den Lüfter meiner Wärmepumpe Stiebel Eltron WPL 10 AC nach dieser Anleitung reparieren. Die Kugellager (2 Stück) sind folgende: SKF 6000-2Z/C3 Rillenkugellager.

can i recover a defect 4ah battery with a 2ah battery?

Just replaced my bearings in a Zhender Q450 with the help of this video. Some tips. Set the unit to Service mode and turn off power. Remove the heat exchanger. Dismount the fan following instructions in manual.Leave the fan wiring connected. Open the scroll housing by removing the 5 screws. Remove the motor from the scroll housing by removing 4 screws. Split the motor by removing the next 4 screws and taking care not to damage the 3 pins that connect to circuit board. Take the plastic cap off the bearing to expose the circlip. Remove circlip carefully with small circlip pliers. The bearing wouldn't move so I had to enlist my sons help to use a punch and tap the centre of the shaft while I held the centre of the motor and that got it moving. The bearing on the base needed some gentle persuasion with a screwdriver from the rear. Check the postion of the two star wadhers before removal. One sprung off before I could check it. I reassmbled with the lower one convex on the housing and outer one covex against bearing (small diameter touching) used of bearing to locate the circlip. Don't forget to reinstall plastic cap. Hope this helps.

We don’t see anything cause you cover the operation with your hands. Also, have of the screen without motion and what’s moves and need to be shown you do it out of the screen

I preload with a car battery charger 30 secounds. It works. Thx

Absolutely doesn't work

What are those things you take out at 3:26? They look a bit like washers. What are they called and where can you buy them from?

Cant see what right way to put in the two discs ?

Thanks for this video, you have helped a lot!

Thanks for this video, was the bearing 608z or 680zz?

3:42 you are not replacing the ballbearing ??? and cant se shit cuz of your hands

Thank you for this video I tried this and it worked a treat....

Whaou !!! Thanks a lot !!! Brillant job. I will try this tricks with drone 🔋 too

Suggestion: this is dangerous for your batteries - you'll lose two instead of one. Probably posted by a Parkside competitor or a naughty boy.

Thanks for you very helpful. It is work again.

i bo bought a 4ah and on charger is flashing green and red,can i jumpstart it with a 2ah working battery?

Thank you for this!! Zehnder doesn’t offer any other assistance than sending a $500 new fan plus installation charges. We installed our Zehnder ourselves in a house we built by ourselves…so just replacing bearings makes more sense to us. We now have a silent Zehnder HRV again. We will do a full clean/inspection every 6 months from now on and will order extra bearings. Would the 608-2RSH/C3 perhaps last longer than the 608-2Z? We have an ocean and marina On either sides of our house so I would like the bearings to be as protective as possible.

Thank You very much for this diy🙂 I've Just change bearings in my recuperator viessmann 300. I have fans: r3g190-rc05-09 and the bearings 608. But I put diffrent than original bearings. I placed 608 2RS C3.

Does this method work with all brands of battery?

Thanks!!!works very good ☺️👌

YOU ARE AWESOME,THANKS!

Thank you! It works perfectly!

Sehr Hilfreich .Habe gerade mein Akku das Leben gerettet. Super Lösung

Can confirm that a 608Z bearing did the job on a danish vent system under brand Nilan model Comfort CT300 worked:)

Thank you so much for the video, you help me a lot !!!

Thanks, it work..

Thx so much for putting this online, it solved the issue I had with an R3G220-RG19-07, in a Zehnder ComfoD 300 Basic.

This parallel wiring saved me 2 Matrix X-One 20V batteries. The charger wasn't able to charge them any more, but it stayed green when they were connected. After the dead battery was connected to a working one for 10-20 secs, the charger was able to fully charge the wrong one and it has started to work with the screwdriver too. Thank you for sharing this solution!

never do this unless you want the battery to burn ... without a light bulb it's completely crazy. (engage in a series on a positive cable) The author of the video is a confectioner graduate and not an electrician.

If you do not have a second battery to connect, you can do the same thing with the cells. Connect a charged 18650 to every cell of the dead battery one by one. If you do not have a 18650 try with 3 AA batteries (or AAA). 20 seconds are enough for each cell

Thank you …… 👍🏼

Thanks for this video, it fixed my battery!👍🏿👍🏿

I had a brand new battery it wasnt charging. Both lights where flashing. I did not have the same battery so I tried an 18v black and decker battery and left it for a few minutes. Wow to my surprise and happiness it worked. I put it on charge and only the red light came on and it was charging. I didnt think it would work but it did. Brilliant saved buying another one

Worked a treat thanks 😁

Thank you very much. I revived a battery thank to your video 👍👍👍

Hi, on 3:46 of the video, it shows two curved (kind of serrated) plates supporting the ball bearing. Are they installed in convex or concave?

It works thank you

Thank you! Worked out very well!

Wow! Just like other people have said, I was just about to throw it in the bin but had one last look on the internet and found this.... and it bloomin' well works! Brilliant trick!

Did not work for my 20v 1A 40wh Parkside batery

I used an adjustable PSU I had for electronics projects which had current-limiting ... set it to 500mA at 21v ... worked a treat & I thought it might be a bit safer... 😎👍☘🍺

This absolutely works! Thanks 🙏

genius!

Worked a treat, thanks a lot
