Wahoo KICKR Drive Pulley Repair Kit
This kit addresses the 'clunking' noise caused by an undersized woodruff key and insufficient fastener tension on the drive pulley shaft. The replacement high-strength bolt and thickened washer provide the necessary axial clamping force to eliminate rotational play between the pulley and the flywheel shaft. Applying the included thread locker prevents the assembly from loosening under the high-vibration environment of interval training.

6001-2RS Sealed Ball Bearing
If the noise persists as a rhythmic vibration or grinding rather than a sharp clunk, the internal flywheel bearings have likely suffered from raceway pitting. This is common in trainers where sweat or cleaning fluids bypass the seals, leading to corrosion and 'notchy' rotation. Replacing the standard bearings with high-quality sealed units restores smooth rotational dynamics.

Drive Belt (Gates 6PJ490 or equivalent)
While less likely to cause a 'clunk,' a frayed or contaminated poly-V belt can produce rhythmic thumping if debris is embedded in the ribs or if the belt has developed a 'set' from long periods of inactivity. A new belt ensures consistent friction and eliminates noise generated by belt-slip or rib irregularities.
