Mitutoyo test indicator repair

I have a model 513-212 which needed a good clean. I don't know how to disassemble the bezel which is not strictly necessary. However I do need to
know which direction I should tension the indicator hand staff upon re-assembly. Anyone know? Thanks, John.

I know nothing specifically about your question but I am prety sure that hairsprings are usually tensioned in the windup direction which tends to wind the coil smaller. It also seems that a rotating pointer should be tensioned in a manner that pulls it back toward the zero point. Hopefully someone else has better information.

Don this indicator is bi-directional so without dismantling the bezel I have a dilemma. John. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

DONE, its fixed, I was able to figure out the direction from the wear on the crown and pinion gears with a high powerful magnifier, clockwise when viewed from the dial side. John. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
