Locate main pump wall and attach with 4x M4 screws with spacing washers beneath head.

Roller Assembly Parts.

Insert M4 screws through the acrylic plate with spacer washers on top. Note that this acrylic plates has larger holes that the M4 screws should fit through easily without screwing.

Insert roller over motor D-shaft.
