Thank you Peter and George, I was able to fix the play by following the instructions!

Shitij,

 

If you still have issues after gear meshing, contact me directly and I can walk you through the procedure.   See the gear meshing link for you specific Mach1 on the Tech page for legacy products:

I just got a used Mach1GTO and am seeing significant play in both RA and DEC axis, is this normal? (please see this video: https://photos.app.goo.gl/8Uc2nCfHHfjcVX3x7)

I read through this post: https://ap-gto.groups.io/g/main/topic/mach1_play_in_ra_axis_did/77208585?p= but my Mach1 is the older version (S/N M10366) and does not have a lever on the side of the gearbox so any instructions for the older mach1 for this similar issue would be great!

Thanks in advance,
Shitij

It sounds like your mount needs gears remeshing. There are many Mach1 manuals available based on year built or serial numbers. Here is a link to manuals for discontinued products. Scroll down a bit until you see "Mach1 German Equatorial" at:
