    Default Gyrodec motor repairs

    I think my Gryrodec motor has dried out, the spindle is very difficult to get going after it hasnt been used for a while. Once I have freed it up using my fingers it works ok until it hasnt been used for a while.

    Sent an enquiry to Michell but no reply. Anyone had a reliable repair done elsewhere?

    Oh my god! There's nothing wrong with the bidet is there?

    “Nothing discloses real character like the use of power. It is easy for the weak to be gentle. Most people can bear adversity. But if you wish to know what a man really is, give him power. This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".

    “You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”

    The motors stiff, not the platter

    If it's the Papst motor with the external flywheel they can be stripped down, cleaned up and work like new again.

    Best of luck

    Heard back from Michell, £54 inc vat and return postage.

    Motor removal is pretty simple, disconnect mains power. Undo allen bolt on top of motor cover, lift up motor and cover place on its side next to platter. prise the rubber/felt washer off the top of the power input socket and slide up the cable that goes to the motor. MAKE A NOTE OF WHICH CABLE GOES WHERE. cut or unsolder the 3 power cables lift off and remove outer case.

    Removal looks as if it will be more diffcult because access to the power socket cables for resoldering is restricted. The arm board assemby and platter will probable need to come off

    An unusual problem because turntable motors rarely dry up/seize in the manner described. Is your turntable motor near a radiator or often in direct sunlight?

    Actually I think michell could be held liable, the qc psu if left on dries the motor out. I found out the hard way but the damage was done
