PicoBox Duo and Chassis Assembly Instructions
Step 26
: Press a 6x12x4 Flanged Bearing (am-
3377) into the center 12mm hole of the Outside
Plate (am-3392_Outside). The flange on the
bearing should be on the same side of the plate
that has the flange. Make sure that the bearing
flange is flush against the sheet metal.
Step 28
: Slide the Center Axle into the center
bearing previously installed into the Outside
Plate, and make sure the flange of the Outside
Plate points toward the chassis.
Step 27
: Flip the plate over and press two more
bearings into the end-most 12mm holes of the
Outside Plate. The flange on the bearing should
be on the side opposite the flange on the sheet
metal. Make sure that the bearing flanges are
flush against the sheet metal.
Step 29
: Secure the Outside Plate to the
chassis by threading four 1/4-20 Self-Tapping
Screws (am-1310) into the four 63mm Churro
Extrusions on the Drive Module. Be careful not
to pinch the belts while installing the Outside
Plate.
Step 30
: Attach the 4x4 Plates (am-3393) to the
Outer Plate using two 6-32 x 0.5 in Hex Head
Screws (am-1436) and two 6-32 Nylock Nuts
(am-1419) on each 4x4 Plate.
Step 31
: Place a 15mm long Aluminum Spacer
(am-3425) into the center cavity of the pulley in
an Outer Wheel Assembly, and place the
assembly in between one of the Inside and
Outside plates ensuring the outermost belt
wraps around the pulley. The belt should sit
parallel to the plates.
