Does anyone know how to adjust mechanical pressure gauges? I tried to fix one this morning and couldn't get the pointer to rest right at the peg. I repeatedly moved the Bourdon tube carefully until the sector ran off the pinion in the low-pressure direction, moved the pointer about
90 degrees backward, then let the sector re-engage. The zero would land slightly on either side of the peg. This 30PSI gauge had been over-pressured to possibly 50, so maybe I should have readjusted it by squeezing the bent link that connects the tube and sector gear but I want to ask before doing this. I don't have a puller for the hand.TIA Jim Wilkins
