Find
the yellow G4 gear, it has a hex shaped protrusion on one side that will
fit onto the gear hub on the hex axle.
Slip
the yellow gear onto the hex shaft as shown. Be sure to align the set
screw with the slot in the G4 gear. You should be able to clearly see the
set screw. If not, rotate the gear until set screw can be seen.
Select
another blue G3 gear.
Place
the blue G3 gear onto the round steel axle as shown in the picture. The
teeth of the smaller gear on the G4 should mesh with the teeth on the larger
gear on the yellow G4 gear.
Find
the small aluminum spacer - refer to the picture.
Slide
the spacer onto the round steel axle as shown in the picture. The space
slides up against the blue gear.
Find
the yellow G2 gear. This gear has teeth on the face instead of the edge.
Place
the yellow G2 gear onto the hex shaft as shown in the picture. The small
gear on the G2 should mesh with the larger gear on the G3
Now
we can slide the 2 housing parts together. Make sure the 2 axle holes in
the middle housing section have the brass eyelets in place so the axles
will fit into the brass eyelets and not into the plastic.
Once
the 2 axles slide into place, the 2 housing parts should fit together
easily. Do not try to force the parts if they don't easily slide into each
other. check the axles and make sure the gears are aligned as shown
in the pictures above. If you still can't get it fit together, pull
the sections apart and reassemble the gears as shown the guide so far.
Find
3 of the 18mm coarse threaded screws like the one shown in the picture.
Place
the 3 screws into the holes on the outside housing as shown in the
picture. There are actually 4 holes but only 3 will accept the screws. The
fourth hole is under my thumb in the picture.
