Qualcuno sa cos'è il bushing saw slot??
Ecco il contesto
REMOVAL AND INSTALLATION OF TAPER LOCK BUSHINGS
Loosen and remove all mounting bolts.
Insert tap screws into all threaded jack screw holes.
Loosen the bushing by first tightening the screw furthest from the ***bushing saw slot***, then, alternately tighten remaining screws.
Keep tightening the screws in small but equal increments until the tapered sprocket/sheave and bushing disengage.

GRAZIE!!!
