- How to dismantle clean, service, rebuild and preload a Mitutoyo Dial Caliper. First how to take it apart ready to clean, then clean and service, and finally rebuild it including preloading the gears to prevent needle jumping from gear backlash.

It took me a while to understand how this preloading mechanism actually works. Once I figured that out and how to put the gearbox back into place without losing the load, it was easy.
Thank you very much, without these instructions I wouldn't have even suspected that it was necessary to apply some preload and would've wondered why the dial wouldn't work anymore.
Well done and thanks for the feedback. You can do it 👍
Love your videos!! You are really what is keeping me sane during this time!
Great help in fixing my own even if mine had a different gear mechanism. Much Appreciated :-)
Great news you fixed it. You can do it 👍
Great video that I stumbled upon rather accidentally,,, as I am actually trying to disassemble and clean a set of Fowler calipers for a good friend of mine...
I couldn’t help but notice, the o.w. marks on the case and the back of your mitutoyo set, and you said that you ordered them from the Internet.
Amazing how they got from central Arkansas too you !!! I am o.w. by the way ,,,
Thanks for the feedback. I bought those from a guy in Austria who must of got them from you 😉 You can do it 👍

Wow,,,
It’s truly amazing how things travel around the world in the days of modern technology !!!
Although,,, history has proven many times that artifacts have traveled thousands of miles away and been traded back and forth for centuries...
I wonder how many craftsman’s hands those calipers might have been through between mine and yours ???
Thanks. Very helpful
Thks for the feedback and glad it helped . You can do it 👍
Thanks very informative
Hope it helps. You can do it 👍
Beautiful; very useful,just did mine,it was a bit magnetized and had metal chips inside on the gears;
Just onemore little thing,the sound could be a tad higher,we can barely ear you;
Thanks.
Hi glad it helped. Yes sorry sound is crap was one of my early videos and I was in a rush to fix these so I could finish my KTM 300 engine rebuild for an event. You can do it 👍
Nice unit. I have the imperial version of these. They also have a metric scale on the rule, but the dial and fine increments are SAE.
Hope you get yours fixed. You can do it
Thanks for the video! I have a set of No. 505-627-50 calipers. I am having extreme heartburn trying to remove the needle! I mean, I am REALLY prying up under the center section. I am using a pair of tweezers to straddle the stem. I placed a razor blade on top of the dial face to absorb the force. Your thoughts?
They can be on there tight 😳 You can do it 👍
There is a special took for safely removing the needle that I see from time to time on a couple of watch b repair channels. I do not know what thebtool is called nor dobI know the costs. But I 'd bet dollars tobdonuts that there are people in this c I m ments section who do know. There are quite a few people here that obviously know more than I do.
Hi can anyone help me out i have lost the long shim during servicing the same caliper i just want to know the thickness of the shim i will machine it myself anyone's swift reply would be highly appreciated
Hi sorry I cant help there. hopefully someone will chip in. You can do its :)
Mine are 505-633 callipers and in desperate need of a service. They became so bad that I stopped using them. Looking like today is the day to see what is inside.
Keep us posted. You can do It :)
@@youcandoit1828 My calliper is 0.05 accuracy as opposed to yours at 0.01 accuracy. The complexity was much simpler to deal with. Only a single pinion wheel running on the rack and the needle attached directly.
All clean and functional.
@@Phil_Cleaver Good work, You can do it 👍
You started strong. Then your volume dropped. Imagine if you will. A half deaf machinist trying to watch this.
Hi Apologies I made this video really quickly as was building up an engine and need the calipers fixed. Thanks for the feedback.
I have to agree with this comment as I am half deaf and did experience difficulty understanding in some parts. That said, thank you very much for making this video. It was quite helpful!
Would you like to sell this Mitutoyo to me? I need a good metric one in my lab. Let me know :-))
jesus man get more concise. no one needs all this exhibition
Exhibition ? You can do it 👍
