Wahoo Kickr Snap 2 bearing replacement guide

[phenning]

My Kiclr started to become very noisy  after 5 years of use. i was not able to feel bearing play from outside, but could also not tribute the noise to something else.
I contacted the local distributor for service instructions, although they were quick to respond the  official reply was "the bearings are  not  replaceable"

 So  here is my guide on replacing the  snap 2 bearings

Bearings:

• 2x   6003 RS2  (they are dirt cheap)

Tools:

• good (low tolerance set of hex keys)
• 19mm socket on impact driver
• 12mm wooden dowel and hammer
• Circlip pliers

Procedure:

Open the cap on the non fly wheel side and remove the  circlip ( you will probably find rust dust ) so clean out as you go along

 

Remove the cap on the fly wheel

Use the 19mm socket and impact driver to remove the  nut holding the fly wheel ( without a impact driver its almost impossible to  hold the flywheel and crack the nut  lose ) 

 

Carefully slide the fly wheel off .. not a key in the axle witch you need to remove and put aside for now 

check that the white sicker is not coming lose or dirty (its the optical speed pickup reflector and can be replace  if required) 

 

Remove the grub screws on the roller. they are locktited in well and you need a perfectly fitting hex key to get them lose 

 

Using a wooden dowel or similar , tap the axle out from the  non flywheel side, if there is no rust it should be quite easy.

Gently tap out the non fly wheel side bearing and remove old flywheel side bearing  from axle

Clean off all the surface rust on axle and bearing seats  and clean up anything that looks dirty

I used lots of grease on everything  put back. 
Place new bearing on axle and shaft down to flywheel end 

Place new bearing in non flywheel side 

Reinstall the axle from flywheel side sliding it through the roller and other side bearing

Install circlip

Align Roller with notches in axle and  tighten down the grub screws 

Replace the Key and Fly wheel and bolt down

replace cap and non flywheel side cover and you're good to go 

Done!
