When comparing the instructions booklet parts and build chain this part is not included.
See Note in the Inventory:
Redesigned during production.
There are at least 2 different versions of instructions for this set. The differences
for the second version are indicated in this inventory in the Alternate Items
section with Match ID 99.
Quick overview of redesign: A special worm screw is replaced by a standard worm
screw and a 5-long stop axle. The worm screw is used in the alternate model
which combines this set with 42027-1.
