DRUM BACK/BAND NUMBER CROSS REFERENCE
In the process of manufacture, Centrifuse brake drums
are assigned three different part numbers - for the drum
band, drum back and the drum itself (see illustration).
To avoid confusion and possible misapplication when
ordering replacement drums, refer to the CENTRIFUSE
DRUM part number.
This is for your convenience in matching drum back
numbers to CENTRIFUSE DRUM part numbers.
