Assembly and integration instructions for the gearbox sub-assembly. Component numbering per Tables 2–3.

Step	Instruction
1	Press the one-way bearing (18) into the leadscrew-gearbox connector (2) using a vice or press. Ensure the bearing is orientated so the leadscrew can rotate freely in the direction indicated in step 4 of Fig. 5, but lock in the opposite direction.
2	Insert the shaft of the gearbox (19) into the connector so that the connector sits up against the flange of the gearbox. Insert grub screws (35) into the threaded holes, and tighten onto the shaft using a 1.5  mm hex key.
3	Press the gearbox and connector into the gearbox housing (3) so that back plate of the gearbox sits on the bottom face of the rectangular cut-out.
4	Integrate the leadscrew and gearbox sub-assemblies by pushing the one-way bearing onto the leadscrew shaft, and screwing the housing components together.
