    The old AC motors have two sintered bearings. If they have dried out then they can be oiled but they won’t be the same as before they dried out, you might get a year or two before they will need doing again. You really need to strip the motor down to lubricate it because if you oil it from the top, it could make the motor noisy, as you will be lubricating the series of washers on the top of the motor and they can then begin to vibrate. You can try using something thin like ZX1 or WD40.
    The best thing would be to send it Michell , so they can then replace the washers and circlip etc. and give it a good clean out and lubrication.
    If you are using a QC power supply with it, make sure you turn the QC off when not in use. The QC has a current path to keep the motor warm, over a long period of time this will speed up the bearings drying out. received from MIchell engineering in 2019

    the Final cut...This is my Gyrodec, with the new version of Pete's pads...The cup has been shortened, so the need for an internal spacer is not required..These are really exceptional for total isolation of the deck from the feet..The inner workings of the pad, see that there is no connection between the aluminium cup and the spider. As an added bonus, these look stunning too, which was an important factor in the later design stage...The set I had previous to these, were just a bare version with a carbon fibre jacket. the half inch thread which takes the foot, was a stub machined from mild steel..This version worked very well, but the newer aluminium cup version, has the half inch threaded stub machined directly in the design of the new cup, making these units something quite special....an impressive piece of work TPA...The noise floor has been lowered even further with this unit and is another modification for the Gyrodec, that lets you here more of the music..a marvelous little piece of design and engineering..

    hi alan thank you for the above, i have sent some out for test and review by other people, as with the pylons i wont tell you what i think , i would only be blowing my own trumpet , i may have some more as test parts , how ever i dont know yet if that is possible the cost is quite high , for the parts due to the maching involved, By TPA , short batches cost alot more , due to the same set up ,

    the reson why they are called Pads was becuse i wanted to use a the tender foot of the gyro and orbe,it is also a nod to the design features on the gyro ,and past decks , i did not want to add a big spacer this would push the cost up , i think the difference in height to the std foot is 7mm, there are plans just to put a piece of acrylic 7mm thick to lift the motor to keep every thing on the same height , they will also be anodised , they seperate the small post inside the suspension from the tenderfoot ,
    that is all you need to know,

    hi all i hope you are all safe and well, i need to know the thickness of the spider / plinth , if you order the pads, this is becuse over the years Michell has changed the thickness of the Acrylic and reducing the amount of thread you screw the pads onto
    so insted of having 9 mm off thread you will only have 6 mm off thead that hangs down under the acrylic , i just have to adjust the height to compensate for this, it is an easy thing to do
