My tumbler packed it in last week through shot bearings. Maybe living near the ocean has an impact but that bearing closest to the counter weight which creates the vibration certainly takes a pounding. Although the unit was well within warranty (purchased direct from the US) shipping cost made that option unviable.
Anyhow managed to disassemble the unit & replace the bearings for around $10 & machine works fine. The bearings can be procured much cheaper on ebay but I preferred to deal with a supplier of accepted product quality.
I thought I would tab the bearing replacement in case anyone has a similar problem.
1. Remove the lid:
2. This exposes the locknut which holds the media barrel to the motor body. Remove the nut & barrel:
3. This now leaves the main motor housing & vibration platform:
4. Turn the body over & remove the three rubber grommets (by hand) and the two cable securing screws & release the bottom cover:
5. Remove the 4 locknuts which secure the motor to the motor housing;
6. Detach the motor cabling from the retaining clip:
7. Remove the four long screws which connect the motor to the motor housing:

8. This enables separation of the outer bearing housing. Using two screwdrivers resting on a side cushion remove the outer bearing:
9. Remove the fan from the motor shaft-I found it could be removed by hand pressure:
10. Remove the counterweight from the motor shaft which is secured to the shaft by a grub screw. I found this to be the toughest task. It required heat around the counterweight to free the grub screw;
11. Remove the front bearing. I used a small gear puller but there would be other means if a puller is not accessible. This enables the motor shaft to be released:
12. I purchased replacement bearings from a reputable local bearing supplier cost $10.30 the pair. The specs are 19mm OD, 6mm ID, 6mm wide. After cleaning components slip the bearings on to the motor shaft:
13. The assembly is a reversal of the disassembly process. Do not forget to reattach the ground wire to the relevant motor securing screw.
