Fixing your Wahoo Kickr 18 Core

Fixing your Wahoo Kickr 18 Core

When you have three family member hammering your Wahoo Kickr it was eventually going to fail. Our team Silversky unit developed a whirring or rough bearing sound, a common issue in older units apparently.  You don’t need to be especially handy to fix it, just patient and don’t rush the job. Full link below to doing the job. The problem bearings are main ones, these are called 6003ZZ link here. The biggest issues I had were:

• Removing the main pully off the flywheel shaft. I had to buy a specific crank pulley that got it off…that’s the only tool I needed to buy.
• Removing the flywheel was an issue once the pulley wheel was off (the thing lying on the ground with the shaft pointing up in the pic), the bearings had rusted on one side…lots of WD40 soaking overnight and a rubber mallet and it came off. I replaced both bearings via tapping them out with a hammer and chisel, and installing the new ones with a bearing press (just a bottom bracket one I had lying around).

Now the Kicker is back to being as smooth as silk, no noise, and I ordered 4 bearings so if it happens again they are easy to replace.
