I had the same problem. The fix took me more like an hour since I'm not as experienced in repairs as you, clearly. However this is much less time lost than taking it to a shop or shipping to Wahoo! I shared your link with my bike mechanic - he had not seen this particular problem even with having sold many Kickr's!
I have a failed speed sensor and hoping Wahoo will provide new with circuit board for customer DIY repair. This video provides head start with disassembly. Looks like Wahoo is now using Loctite on their pulley and shaft key as a bandaid for another engineering mistake. Disassembly of the pulley will be difficult without applying heat as you suggested if they indeed use Loctite.
Great video, really helpful. Managed to get pulley off after worrying I was going to damage it but quick questions about reinstalling bearings: 1) what grease would you use to repack these kickr bearings (might as well do that before they go back); 2) what oil or grease would you use on shaft and around outer edge of gearing where sits in housing. Assume you don't want metal to metal contact but equally assume you don't want whole unit rotating. Advice pls and even trade names of products.; and 3) outer surfaces of reistance magnets slightly discoloured brown ish- doesn't just wipe off, wet finger does nothing and wonder what surface cleaner I could try while flywheel off. Thx!
Hi Tony, As far as the shafts and such go, any grease will work fine, but if you get a good quality wheel bearing grease, then just use that after. The bearings are sealed, but you can pop the seals out, and if you nick or damage them, it's ok, as your trainer won't actually be subjected to water and such. There's too many brands to recommend one... Belray, Superlube, Maxima, Motorex are some great ones.
Great vid! As always! Funny to see that your flywheel has two noticeable marks. I imagine to balance it. Mine didn't have that as it easily came out of true. The first batches I guess didn't have that.
Max! Thanks for your video! Do you know how to remove the shaft from the weight? My shaft got eroded on the base of the bearings and I need to replicate it in a boring machine! Thank you very much!!!
Wow... big job... That's a problem for Wahoo. They should send replacement parts. I don't think you can "fix" it. It has to be PERFECTLY CONCENTRIC... I mean PERFECT. Any tiny amount not PERFECT will make it wobble and vibrate so bad you won't use it ever again.
Any chance you know the part number of the pigtail connector that goes into the back of the kickr and connects to the motherboard? Yahoo is out of the connectors and they used to issue them to fix worn connectors but are now out of them. Any help is greatly appreciated. Cheers.
Great video! As others have said, it gives a better understanding of Kickr anatomy (I have a Core), even for those of us who don't know one end of a screwdriver from the other. Clearly, you know how to remediate the situation, but did you consider contacting Wahoo? They have a reputation of replacing defective units, even outside of the warranty period (they replaced mine recently). They pay all shipping, etc.
They are a great company no doubt. I was able to avoid the aggravation of breaking everything down, and going without my trainer by just DIYing it. There's a lot of people who will watch this video that aren't in the USA and can't just get one swapped out easily.
@@Traxxion good point. I'm in the UK and luckily had kept the original box and packing. Still took a fair while to dismantle, remove from the rocker plate, etc., and of course put the new one together and replace it on the rocker plate. I think I was without for just over a week.
Hi Max, mine has a different issue, it’s starting to get loud and the resistance will just randomly gets high and wattage goes up really high. I would stop and get going again but the reading is way off. I don’t know if that makes sense but any idea what might be my problem? Thank you
How's your Kickr holding up? How long did you have it before you made this video? The drive shaft seems to be in decent condition compared to many that I've seen. I'm wondering if the condition of those shafts are related to "vibration" of the flywheel at higher speeds (caused by being out of balance). Is your Kickr pretty smooth or do you have vibrations at higher speeds?
Mine had maybe 2000 miles on it when it failed. It has no vibration at all, they are very nicely balanced. New bearings only cost a few dollars if you want to change them. Bearing Number: 6003 2RS
great video. i have been having issues with my kickr. when i'm in high gears there is extra noise, and recently i have noticed some black dust on my chain stay and floor. did you experience anything similar. cheers
I can't seem to get the flywheel axle tapped out as it's so tight in the bearing. Any tips, besides using a bearing press? Knocked it quite a bit already with a 2x4 in the middle.
@@mattbannantine9651 yes. Found a block of aluminium and used that instead of wood. Wood is a bit too soft as it absorbs the impact. At the same time, Aluminium is softer than steel, so it won’t damage the flywheel axle. When I got it off there were some rust spots on the axle.
Anything will work on the shaft. The bearings don't spin on the shaft.... the inner race of the bearing sits on the shaft and the outer race and balls spin around it. Repacking a sealed bearing is a bit tricky, you have to pry one of the seals off one side with a razor blade at the inner race. It is possible to nick the seal surface. If you do, it doesn't matter as the bearing will never be exposed to water. Then any high quality bearing grease will work. Moly isn't the right application.

Good to see the inside of the flywheel. I point a small fan at the vents full blast during workouts. That flywheel gets really hot.
nice idea.

Thanks Milo!
Great explanation, even though my issue is related to a Kickr Core, this helps understand the anatomy of the system greatly. Thx!
Glad it helped!

I've always wanted to know what the inside of one of these looks like.
You can use a crank puller to remove the pulley. Someone else mentioned it as the inside of the pulley is threaded
It depends on the version of the kickr. On a v5 it is not threaded
My Kckr seized and this was exactly the problem. Easy fix with you video. Thanks!
WOW! That's awesome, I am glad this helped someone!
looks similar to my jetblack volt. The jetblack/zwift does not have electrical tape on the wires.

Thanks for the tip.I have that problem to
Glad to help!
Max!!! Any insights on how to replace the main shaft to the external weight?
No idea...
Just done it. Very clear and informative. Thanks
Happy to help!

Very sorry Les, that exceeds my paygrade!!! I hope mine doesn't go bad!
Exact same thing just happened to mine! Lifesaver of a video.
@@Traxxion was a nightmare getting the actual flywheel off as its obviously stuck pretty tight. Had to put a long bolt in and basically hammer it off.
@@mf0u3021 Glad this helped!

Hello what can be the noise coming from the flywheel? Please advise thank you
Bad bearing or bad belt most likely.
@@Traxxion thank you. I appreciate you replied.

I don't have any guess as to that. I would hit up Wahoo Support.

Black dust is very likely your belt wearing out... you should open and inspect it.
@@Traxxion thank you for that, i'll have a look. thank you

Heat gun. They are cheap and at Home Depot.
Jeff Phoon, any luck getting the fly wheel off? Looks like I’m in the same position, beat the heck out of the spindle and it’s not budging
@@mattbannantine9651 yes. Found a block of aluminium and used that instead of wood. Wood is a bit too soft as it absorbs the impact. At the same time, Aluminium is softer than steel, so it won’t damage the flywheel axle.

What kind of grease do you recommend for the bearings and shaft? Moly?
Anything will work on the shaft. The bearings don't spin on the shaft.... the inner race of the bearing sits on the shaft and the outer race and balls spin around it.

Moly is intended for sliding surfaces, not for roller ball bearings.
Where did you get that rocker plate. Nice.
It's the Axxion Rocker Plate. traxxion.com/axxion-rocker-plate/
It my product, available from Traxxion Dynamics! www.traxxion.com
I tried to tap the flywheel out but it seems quite tight. Besides knocking it a bit harder, any tips for removing it?
Heat... heat it up with a heat gun or a hair dryer.
Hi should i just heat up the axle ? Or where the bearing contact with axle...thx for the video@@Traxxion
Why do you not have optical tape on the fly wheel
Where and why would you put tape on the flywheel?
@@Traxxion it's supposed to have a small piece of reflective optical tape for the optical sensor.
@@stevebyrnes9574 Mine is a 2018+ model. It's exactly how it came from Wahoo to me.
@@stevebyrnes9574 You can see black and white stripes inside, in the middle of the flywheel. Those are for optical sensor.
Great video
Thank you
Thanks for this!
My pleasure!
Great video.
