Step 39 Auto Hub Spacer
#HW6054
M10x14x3.5 Spacer
Before the main gear assembly can be installed this spacer must be positioned
in the recess of the lower bearing block assembly, it will simply self align in the
block. Slide the main shaft through the upper bearing block, the constant drive main gear assembly, the spacer and finally
through the lower bearing block assembly. Look carefully through the two open M4 threaded holes in the top hub and align
with the hole in the main shaft. Insert and press the M3x15 steel pin through the hub and roughly center it in the main shaft.
Using a permanent marker, mark both holes that will lock the pin in place. Insert the M4x4 set screws in each side and tighten
them equally, using L242 Blue threadlock. These do not need to be torqued down.
