Revision 2.0
Figure 5: Removing the two screws that mount the speed reducer and declination axis motor to the
worm block assembly.
Note the lower socket head cap screw has a washer, the upper screw does not. Please
make sure to replace the screws in the correct holes during reassembly.
The lower screw fits into a slotted hole that allows the gear reducer to be rotated around a
pivot point created by the upper screw. Rotating the assembly counterclockwise (as
viewed in Figure 5) allows belt on the reducer’s pulley to be easily removed. During
reassembly, be sure to rotate the speed reducer fully clockwise (as viewed in Figure 5)
about this pivot point to restore the original tension in the larger belt.
The declination axis motor and speed reducer can be placed on the top of the mount.
Securing the assembly with masking tape is a good idea.
Remove these two 7/64-
inch socket head cap
screws hex wrench.
