Revision 2.0
Figure 4: Removing the back portion of the declination worm block cover.
IMPORTANT:
Rotate the declination axis balance knob fully clockwise to separate the
worm from the gear. This also move the declination motor so you can access the four
socket head cap screws that are located near the lower portion of the cover. When
removing the socket head cap screws, while rotating the T-handle hex slowly be sure and
apply downward pressure at the same time so the wrench does not slip.
When the cover has been completely removed, rotate the declination axis in either
direction until a hard stop is encountered. By doing so, the mount’s internal homing
sensor index (that is part of the gear) is completely out of the way of the homing sensor.
The next step is to remove the two 7/64 inch socket head cap screws that mount the speed
reducer to the worm block assembly as shown in Figure 5.
Step 2: Remove the
four socket head cap
screws using a 3/32
inch T-handle hex
wrench.
Step 3: Remove the 3
x 3/32 inch socket
head cap screws using
a T-handle hex
wrench.
Step 1: Rotate the declination axis balance knob fully clockwise to
separate the worm from the gear.
