Cleaned and re-greased RA worm block

I used the same procedure again to remove, clean, and re-grease the Right Ascension worm block.  Some photos:

I then ran the mount through several iterations of exercise, and all seems well.  Even motion, no stalls, no weird noises.

Finally I did the manual mechanical check for hysteresis on both worm blocks, and no motion detected in either case.  I think I’m ready to start polar alignment – just need the couple of days of forecast thunderstorms to pass.


Cleaned and Re-Greased DEC worm block

Following the instructions in Bisque’s video, I removed the Declination worm block, cleaned all the grease out of the drive gear and the worm gear, and re-greased.  Because of our winters, I used MolyKote 33, which is rated for much lower temperatures than the standard Lubriplate 103 that Bisque normally uses.

Some photos of the cleaning process, but I forgot to take photos of the re-greasing:

I then reassembled the Dec worm block into the mount and reset the cam stop and spring plungers to factor spec, and ran the Dec motor through 10 end-to-end exercise runs.  I ended up backing the spring plungers off 1/8-turn more than the lower end to eliminate a slight binding noise I could hear in the exercise.  (The manual specifies 2.5 to 3.5 turns back from bottom.  I ended up using 2-5/8 back from bottom.)

Next I’ll do the same procedure with the RA block.
