To Peter and Phil, thank you for your suggestions. I will be home on the weekend and will try a thorough solvent cleaning to see if that can solve the apparent stickiness of the planetary drive.
Joe, thank you also for your suggestion and pointing out that the drive is on the Plate tuning rather than Load. Not sure how I let that mistake get out.

Update. I have tried cleaning the reduction drive but it did not help. I have a suspicion now that part of the problem may be that there is simply too much tension on the shafts. I have tried cleaning it with Deoxit (DN5) and used some WD-40 but I cannot get either the Load or the Plate to turn smoothly. I have another L7 to compare against so I know that the ones I am talking about are tight. Can anyone suggest the best way of lubricating these shafts?
I have now ordered a replacement from Midnight Science, thanks for the suggestion.

WD-40 is one of the worst you can use as a lubricant. It's a water displacer and contains paraffin.

Get some Tri-Flow. It's high quality synthetic oil with microfine particles of PTFE. Shake before each use.

We are Coulomb of Borg. Resistance is futile. Voltage, on the other hand, has potential.
