Hi Ron,

Your reply gave me impetus to pull another Philco off the shelf to go through the cleaning and lube of the dial drive mechanism. Couldn't recall much from 7 years ago.

Were you having trouble getting to the mechanism shown in the link below to remove it from the chassis?

If so maybe you didn't realize the setscrew had to be loosen on the sector ring piece. This is not so obvious. Then you pull out the axle and hub the dial scale rides on.

The dial drive reminds me of a planetary gear system except it uses ball bearings instead.

Once you have the dial drive mechanism out. Now you can take it apart to clean and lubricate the inner workings. The grease typically has become petrified. Pull the retaining clip off. Next you will need to push in on the center shaft (fine tuning) to unload the ball bearings, then the innards will pull out of the housing. The cutaway drawing in the link show 2 ball bearings (3 total) against a tapered shaft, actually it is somewhat concave which keeps fining tuning shaft in position. Prefer white lithium grease.

Hopes this was of some help.
