FAQ 

Q: Can bushing with light scratches on copper layer keep working?
A: Not recommended. Scratches will wear the shaft and clearance grows rapidly.

Q: Can I only replace bushing if shaft is worn?
A: No. Shaft and bushing are mating pair. New bushing will wear fast on worn shaft.

Q: What happens if oil hole is misaligned after pressing?
A: No lubrication supply, dry friction burns bushing quickly.

Q: Only one bushing damaged in planetary set, can I replace only this one?
A: Not recommended. Remaining bushings are fatigued and will fail soon.
