How to service Mitutoyo dial calipers and how to fix Mitutoyo Dial needle from fluctuation giving false readings. Details how to try different preload settings
Very good series. I have a caliper to fix myself. I'll use the videos (also mitutuyo, but not this brand exactly) so - thank you so much for the help and videos posting!
I found all three videos extremely helpful thanks. My 505 has a regular clunk as I go up and down the rack so I want to disassemble it to find the problem. I figure it’s probably a piece of grit stuck in a cog. I had no idea about the preload. Thanks heaps, Stuart 🇦🇺
Great series of videos,,, even though I’m actually disassembling a set of Fowler calipers, they are actually built about the same, except a couple of the plastic parts on the mitutoyo model are either aluminum or stainless on the Fowler brand. And the Fowler brand has three set screws on the back shim instead of two ? Thanks for the information !!! o.w.
Are both the gear wheels spring loaded with same spring tension? Or only one them? In my caliper, spring loop from one wheel is coming out. Please help
@@youcandoit1828 thanks for the help! One of the gear was worn out. So i changed it from another damaged calipers. And yes one of the gear is in 'full-on' spring tension, the other one has very little spring tension. I just placed the gear train on the rack. No preload or anything. Still trying to figure out how to preload. So that needle does not jump one or two graduations on dial when bought back to zero.
i did the exact same thing. tried to press in that little slot ont he bottom to reset the needle to true north, and square the dial to the ruler but it seems like press their did nothing so i just backed away and ill leave it cock eyed :P
Hi yes some dials seem to have a reset function and other don't. You can do it. If all you want to do is reset the needle you can do that easily by. taking the dial cover off remove needle and reset. You can do it
