NOTE: Shown above is the pump - drive component schematic. There are some items from the tractor
that will be reused and some items that are only available as an assembly. The tractor from the
manufacturer has a thin spacer bolter to the crankshaft pulley, remove this spacer and reinstall the spacer
from Alamo Industrial using the same four bolts that mounted the tractor factory spacer.
