* Belt dimensions given are nominal dimensions. There is a
set-up must be inspected when a new belt is installed and, If necessary, clutch set-up must be adjusted.
The drive belt is an important component of the converter system. In order to achieve maximum efficiency from
the converter, drive belt tension (deflection), clutch offset, and alignment must be adjusted properly.
