Subject:	DSX Mount

I am trying to remount an older 'ETX-90 RA on a DSX mount, a DS 2000 I
believe.  The problem is the altitude drive doesn't work under the
weight of the 90 RA.  No matter what tension I put on it, it doesn't
want to move in the up direction.  I'm thinking I might be missing a
washer or something.

I have looked on your sight but I can't find any info about the
construction of this mount.  Perhaps you or one of your readers can
direct me to a site that has the plans or pictures of the internals of
this mount.

Thanks again for the great site and sorry to hear of the theft.
Mike here: There are 8 ETX on DS mount articles on the Helpful Information: Telescope Tech Tips page but they don't go into the DS mount construction. You might find them useful however.

And:

Thanks for the reply.  I think there is a problem with the clutch
mechanism.  I've looked at most of the articles on the DS mounts on your
site, none so far are any help.  Thanks again for the reply.

And:

I figured it out.  I took the mount apart since it wasn't doing me any
good.  The clutch assembly is a simple friction fit.  The problem with
mine was there was some grease on the large washer that make up the
clutch.  I cleaned it off, matter of fact I cleaned off the entire
inside of the arm and now it is working.
