    Default Replace Board Sensor Wire

    Hello.

    I got the "Clear Board Sensor" message. I removed the board sensor and took <80 psi air to it. When I reinstalled it I had two problems.

    1 - the black plastic rings for the screws broke
    2 - Apparently I don't know how to push wires back in without cutting one

    Now I have a new set of problems
    3 - I have a broken board sensor mounting bracket. I saw pictures that people built a replacement with a thin metal plate. I plan to do that.

    4 - I ordered a new wire set. I have NO idea how to get the old wire set off and the machine prepped for the new wires.

    5 - The screws are stuck and stripped

    The broken wire was likely pinched along side the wire track and no way to get it without snapping it... See the pictures I posted the other day. I am in a rush at the moment.

    You need to DRILL out the screw heads. So order 4 replacement bearings and screws. I would order double the screws, 8 as you can easily snap them installing the bearings and getting the bearing rotated into position. You can remove the drilled out screws but I would have bearings on hand.

    Do you have a thin Bearing wrench? Ask LHR

    I would order a new board sensor too. Keep the other one for a spare.

    I would order 2 FFC Cables now to save on shipping later.

    I would order 2 or 4 Cut Motor (Bearings) EDIT: I meant BRUSHES... sorry) now to save on shipping later.

    You must remove the Y Truck.

    Good Luck,

    Wow! Thanks a bunch.

    I called and ordered everything you mentioned. When talking to the rep, I was able to get a plan of attack.

    We'll see how it works out.

    Thank you very much. Here is my current situation. Wired replaced and screws are VERY stuck. I used hair dryer, soldering iron set at 600 and a blow torch.

    Any ideas?
    Are the black bolts to able from the bearing?

    I have played that snapped off flush game before... I have some bearings in my junk box with snapped screws. The good news is that the bearings do have a center that can be pressed out....

    That is why I always recommend buying 8 screws and 4 bearings.... And I HAVE had the bearing screws come loose when I did NOT put locktite on them... So that is asking for trouble if you don't.... That is the advantage of drilling the screw head as it leaves a stub you can remove easier than snapped flush.

    I think this is the bearing. Not 100% sure. http://www.vxb.com/LFR50-8NPP-8mm-ID...-p/kit8369.htm

    I use a small butane torch to break the Loctite down. Pencil type work very well and HF sells them a cheap price.

    Al.

    When CW sends the new bearing, will it have that nut pressed into it? I'm guessing yes.

    Thanks
