Replace Carriage Bushings
The carriage bushings are rated for approximately 1500 hours of operational usage. Many factors including, but not limited to, hours/ day used, cleanliness of the slide shaft and general ambient environ- ment make it impossible to calculate the average time that the carriage bushings to last.
If not replaced, the wear on the bushings can result in erratic carriage motion and/or carriage axis failures. It can even cause the cartridge head height to become uneven.
To replace the carriage bushings, follow the procedures for Carriage Bushing Replacement found in Chapter 5.
