A worn or damaged shaft is a common problem when repairing an engine. Let's look at what constitutes the price of restoring a shaft and when it is more profitable than replacement.
When restoration is needed
- Wear of bearing seats.
- Development of a keyway or fit under a pulley.
- Deflection or curvature of the shaft.
- Seizing and damage to the surface.
Methods restoration
| Method | Application |
|---|---|
| Welding with grooving | Restoring the fit size |
| Installing a repair sleeve | Broken seats |
| Grooving and grinding | Scoring, minor wear |
| Rediting | Shaft deflection |
Restoration or replacement
Restoring a shaft is usually cheaper than making a new one, especially for large engines. A new shaft is made if the old one is irreversibly damaged (deep cracks). Restoration of seats often comes in conjunction with replacement of bearings.
The exact cost is determined after diagnostics and shaft measurements. Shaft restoration is part of high-quality repair of industrial engines.
