Yes - when a German Equatorial Mount crosses the Meridian, you need to shift the CW on the Dec shaft accordingly, to ensure that the E side of the mount is slightly heavy. This should ensure that the RA gear(s) are always meshed, as the slight imbalance should encourage the gears to always be pressed against each other, rather than have any small gaps (backlash) before the mesh is taken up.

My non-engineers interpretation!
