New Parts needed for this step:
Why is the belt guard optional? Honestly, it shouldn't be. However, it is not uncommon to see units operating without all safety features. To provide you with the ability to display this unit in a way that feels most authentic to you, the belt guard is optional.
The shroud is directly under the pumping unit and the side is at the bottom. They are in the proper orientation.
Install the shroud as shown. It has no groves and is held in place by the pulleys once they are reinstalled.
Reinstall the motor pulley
It is much easier to install the pulleys if they are still connected with the rubber band. If the rubber band did not hold them in place previously, replace the bands in the appropriate pulley groves and stretch slightly to force it into the groves.
Install the motor pulley being careful to route the rubber bands around the standoffs.
If necessary to reposition fingers, the pulley will typically rest in the proper orientation behind the farthest standoff.
Once the rear standoff is attached, rotate the cover down and attach to the front standoffs.
