A680-1431 Belt Drive Roller Ass’y 1 X/O 1
The individual part numbers for the belt drive roller and the 20Z timing pulley are listed in
the parts catalog, but the roller shaft is actually press-fit into the pulley on the production
line.
The 20Z pulley cannot be installed on the roller shaft in the field. A part number for the belt
drive roller assembly has been assigned instead of separate numbers for the belt drive
roller and the timing pulley.
