I believe we are doing maintenance and gear will encounter the same problem when maintenance

Exactly when the gear unit bearings need to replace it?

Within the next gear without oil prohibit driving operation!

Because of acceptable quality lubricants in gear during operation, will be formed in the bearings and other rotating parts to protect the position of the contact layer of thin film to prevent hard on the hard, dry friction of iron on iron. As in the case of oil-free operation, damage to bearings and gears, gear shaft and other drive components!

2. When the running gear, bearing position when unusually high temperatures, to consider whether the stop to check bearing damage, such as damaged and must be replaced immediately, the operation can not be sick, causing damage to other parts, resulting in greater losses.

3. When running gear, bearing position noisy (similar Granada Granada voice), we should consider whether the stop to check bearing damage, such as damaged and must be replaced immediately. Note also that this case is not considered noise bearing issue, there may be sound emitted gear

4. Recommends that the normal operation of 7--8 years, or do a major overhaul, replacement of internal gear all bearings, gears and other transmission parts simultaneously checked overhaul.
