Reinsert the main roller bearings into the DEC worm
gear. You can use a small smear of lithium grease to help them seat into the
worm. |
You may need to use a wooden or rubber mallet to gently
tap the roller bearings into place. This is the bottom roller bearing being
inserted using a wooden handle and is being hand tapped into place. |
Iinstall the DEC
main housing roller bearing onto the top of the DEC axis. This may need to be
tapped into place using a wood or rubber mallet. Lightly lubricate the top of the bearing.

Replace the worm gear teflon washer making sure this is
the same one you removed earlier. Use a small dab of grease to secure it to the
worm gear and make sure it stays centered during the rest of this
procedure. Note: If you
wish to carry out supertuning with replacement shim washers read the supertune
guide HERE |
Replace the declination worm gear onto the DEC main
housing and lubricate the teeth at the base of the DEC gear. Also apply a small
smear of grease to the face of the top roller bearing. Keep the main barrel element free of grease as this will
impair the ability of the DEC scale to be locked when in use. |
Replace the worm carrier onto the mount. Make sure that
the worms motor gear is aligned properly with the slot for the motors running
gear. |
|
|
|
|
|
|
After cleaning out any grease or debris from the
declination collar/spindle assembly replace the teflon washer. |
Replace the DEC scale making sure it is correctly
orientated to the mount (ie make sure it is the right way up for the mount when
assembled) |
Replace the Declination lock 'brass
button'. Note: On the EQ6
being stripped down for this guide this button could ONLY be installed from the
inside. Check with your own mount whether it needs to be installed from the
inside. |
|

Here is the declination lock button installed into the
DEC collar assembly. |
Gently insert the declination collar and spindle
assembly into the mount main housing. Take care that the teflon washer between
the DEC gear and the DEC housing is not damaged during this step and that the
brass lock button does not fall out. |
Replace the cap headed screws on the DEC worm
carrier. |
|

Do not tighten the DEC worm carrier down. Just apply
enough pressure to stop it moving about but not too hard. It will need
adjusting later. |
Wind the upper set screw for the worm carrier back into
the mount but do not tighten it. It just needs to be put back so that it is not
proud of the mount. |
Wind the lower set screw for the worm carrier back into
the mount but do not tighten it. It just needs to be put back so that it is not
proud of the mount. |

Pack the taper bearing with lithium grease and wipe off
any excess. The easiet way to pack the bearing is apply a blob of lithium
grease on the palm of your hand and then force the bearing into the grease.
This will force grease inside the bearing. |
Now reinstall the taper bearing into the bottom of the
DEC axis housing. Do not worry if it will not go all the way. So long as a few
threads from the DEC spindle are showing that is enough. |
Replace the weight bar collar and screw it down. Tighten
it as far as it will go by hand and then back off until the weight bar collar
locking lever is in line with the DEC clutch lever. |
|
|
|
|
|
|
Tighten down the weight bar collar allen headed grub
screws. |
Apply some lithium grease to the declination clutch
locking bolt and then replace the bolt. Screw this in until it is tight and the
declination axis is locked. |
Replace the DEC clutch lever and test that you can both
lock and free the DEC axis before replacing the screw and tightening it
down. |
|
|
|
|
|
|
Replace the weight bar by sliding it back into the DEC
spindle through the top of DEC axis. |
Replace the weight bar safety nut. |
Replace the dovetail carrier. The locking bolts for the
dovetail carrier should be opposite the DEC clutch lever. |
|
|
|
|
|
|
Replace the dovetail carrier grub screws and tighten
down. |
When tuning is completed for the worm gear (see
HERE) the remaining worm
carrier cover can be replaced. |
