1 B-7 Taper BushingInstallationIMPORTANT NOTE: Please follow the instructions on this sheet in order for the Martin Bushing to perform satisfactorily .INSTALLATION1 . Clean all oil, dirt, and paint from shaft, Bushing bore, outside of Bushing and component (sprocket, sheave ..etc .) bore .2 . Insert Bushing into component . Match the hole pattern, not the threaded holes (each hole will be threaded on one side only .)3 . Thread set or cap screws into those half threaded holes indicated by on above diagram . Mount assembly on shaft .4 . Alternately torque set or cap screws* to recommended torque setting in chart below . 5 . On 3535 and larger bushings use a block, sleeve or drift and hammer large end of Bushing (do not hammer Bushing directly) .6 . Repeat steps 4 and 5 until torque wrench reading, after hammering, is the same as before hammering .7 . Fill all unoccupied holes with grease .REMOVAL1.

2 Remove all set or cap screws .2 . Insert set or cap screws in holes indicated by l on drawing . Loosen Bushing by alternately tightening set or cap screws .3 . To reinstall, complete all seven (7) Installation instructions .
