I am not sure what you are asking. Do you want to disassemble the speedometer itself? If so, you carefully mark the wires and remove them, unscrew the nuts holding the bracket in place and pull the speedo out the front. If I remember correctily you need to bend up the edge of the trim ring to remove the bezel, then remove screws from the back to release the guts of the speedometer. Clean everything up and lube appropriately. Assembly is the reverse.
