Hofmann universal dividing head

[john campbell 5Participant @johncampbell5]

Hi, Can anyone help I have operating instructions for my Hofmann UTH Dividing Head. Can anyone tell me were I can get an 'exploded diagram' (internal parts) of the parts, because the spindle clamp is not working even after I put in hydraulic oil.

As an experiment, I put a small ball bearing in on top of the piston and it then clamps the spindle, obviously this is not the correct solution, so in order to identify the 'correct part that I am missing,' I require the exploded diagram.

Thank you john

Possibly the bolt has been replaced for the wrong length. You may only get part numbers.

If you do a site-specific search of this site on Google, there are a number of threads that pop up. Perhaps a personal message to a fellow owner would get you the measurement you require.

The magic Google text (without the quote marks) is:
