Place the bevel cog differential "A4" and the constructed drive axle into the housing base component labelled "A3".
Smear a suitable grease (model construction gearing grease) onto the teeth of both cogs in the differential.
Check whether the two inner bearings are seated properly as per
the figure on the right.
Place the housing upper component "A2" onto the bearings such
that the guides sit in the housing components.
Finally mount the housing upper component "A1", then you can
screw the three housing components "A1", "A2" and "A3" together.
Four long self-tapping screws "S2" (thread length 15mm) are fitted
around the edges and one short self-tapping screw "S1" (thread
length 10mm - see figure right) is placed in the upper middle of the
upper part of the housing.
This completes construction of the rear differential.
