3-8 Troubleshooting
MedTrack CR60 Rehabilitation Treadmill Service Manual
*The type and the rate of bearing noise can help determine which bearing
is at fault. The number of knocks per minute varies with treadmill speed
because the roller speeds change as the belt speed changes.
**Use a mechanical stethoscope or a piece of hose about two feet long, to
isolate bearing problems. Hold one end of the hose near the suspected
bearing and the other end near your ear. Compare several bearings to
determine which is the faulty one.
