Question problem with Grace g-940

Hi everyone

I am trying to set up my Grace G-940 arm; the unipivot. I bought it second hand some time ago and for so many reasons I haven't put it on my other TT (probably because I have been happy with my PS-X60 with PUA-7 tonearm).

Anyway, the pivot seems to lean to the right all the time. Does this mean it has jumped off the pivot? Run out of silicone oil? Or something far more mysterious?

Any assistance is greatly appreciated

yes, as far as I know. It appears the lateral balance weight is not heavy enough to straighten the tilt

Then something is hanging up. What does the pivot point and the cup look like?

Thanks Dave. I will have a look inside. I was trying to see if there was a simpler solution but it seems not. C'est la vie

Have you checked that the wire between the pillar and the arm tube has enough freedom?

I would also look around on Vinyl Engine | The Home of the Turntable, there is likely to be someone who may have a specific recommendation as to what the problem may be.

Is the Cartridge you are using in the recommended weight range? (not tracking force)

The fact that you have no cartridge installed may be the root of your problem. The uni-pivots I have owned all required a cartridge to be installed before adjustment of the lateral compensation weight resulted in proper playback geometry. Find an old cartridge or possibly purchase the one you intend to use and then try to set the arm up - I think you will find it works a lot better.

I concur with Kevin. Without the mass of the catridge, it won't balance ...
