Bearings are a consumable component of the engine, and their condition must be monitored. Let's look at how to check bearings in simple ways and when it's time to change them.
Checking methods
- By ear. Attach a screwdriver or stethoscope to the bearing shield - a hum, knocking or grinding sound indicates wear.
- For play. Rock the shaft radially and axially direction - noticeable play means wear.
- For rotation. Rotate the shaft manually - rotation should be smooth, without jamming or crunching.
- For heating.Overheating of the bearing shield during operation is a sign of a problem.
Symptoms wear
| Symptom | Degree |
|---|---|
| Smooth hum | Initial wear, lubricant has dried up |
| Knocking, crunching | Damage to tracks |
| Backlash shaft | Excessive wear - urgent replacement |
| Heating | Lack of lubrication or misalignment |
When to change
Any knocking, crunching or play is a reason for replacement bearings. Tightening threatens the rotor touching the stator and causing expensive rewinding. An accurate assessment of the condition is provided by vibration diagnostics.
