Typically when a feathering propeller is very old or has been neglected or run without grease, wear can develop in the propeller in the form of loose blades and backlash. If wear is minimal then it is not usually worth doing anything about and will not cause any problems. If however upon assessment wear is considered to be severe then the propeller can be reconditioned to almost as new condition adding many years to the life of the propeller! As well as dealing with wear, the propeller will routinely be cleaned, balanced and re-finished. We also have a large stock of spares where required.
