    Default Brown & Sharpe 599-579-4 caliper repair

    Does anyone know how to remove the housing of this caliper to get to the movement. I have had my 599-579-3 apart a few times and it has three screws holding the housing. I can't find any relevant info at LI Indicators for the -4 model. On the later models it is pried off, and I would guess that is the same here, but I don't want to wreck anything. Stu

    Thanks for the offer, but I have had Digimatics in the past and much prefer dial calipers. Nothing wrong with them just a personal preference. Stu

    Not being able to see the other end of the caliper, I would guess that there is a screwed on end plate which can be removed. The rack will also have screws holding it on. Then you should be able to slide the moving jaw right off.
    Wait for further comments before proceeding, in case my advice is wrong.

    One is missing the battery cover (in the chips) but works well, the other is much newer.


    I also have the plastic boxes that they came in, I know this is an important feature for many.
    Far to many plastic boxes in fact.


    First shipping address gets them

    probably safe to assume if there were obvious screws on the other side it'd be apart by now....you may have to slide to slide it off the beam in search of a screw behind the beam. Is the stop held on with screws or something more permanent (iirc Mit fixes them with little plastic rivets , B&S I think are better with screws but cant 100% remember ).

    I found a video showing that the housing does indeed pry off.

    Those "how to" you tube videos are really useful.
    Bented, I seem to have seen Mitutoyo battery covers in their spare parts lists.

    I bought that one the early 90's, lost the cover in the early 10's and was told they were no longer available for that model. Did not notice that the cover had fallen into the chips until AFTER I had cleaned out the pan of course.
    In the chip drum it went.

    Don't use them any more because now I do mostly CNC lathe work where coolant is dripping everywhere inside the enclosure, if one drop gets on the scale they stop working until they dry out.
    Oil does not seem to bother them but 80% water soluble coolant causes them to lose position. the IP 67 ones appear to solve this problem so I may buy one soon, they are a bit more expensive however.
