Replace Carriage Cover/Carriage Bushings
The carriage cover bushings (2 total) are rated for approximately
2000 hours of operational usage while the carriage assembly
bushings (4 total) are rated for approximately 4000 hours of opera-
tional usage. Many factors including, but not limited to, hours/day
used, cleanliness of the slide shaft and general ambient environment
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 Car-
riage Cover Bushing and Carriage Bushing Replacement found in
Chapter 5.
