Replace Carrier Bushings
The carrier 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
carrier bushings to last.
If not replaced, the wear on the bushings can result in erratic carrier
motion and/or carrier axis failures. It can even cause the cartridge
head height to become uneven.
To replace the carrier bushings, follow the procedures for Carrier
Bushing Replacement found in Chapter 5.
