Gents,
The following applies to most all "idler wheel driven turntables (TT's)"
Motor must be held in an exact location by the grommets. Motor must be oiled (top and bottom)--some have an oil tube for the bottom, others, not. Those without a tube, must be removed to access the oil "hole". Shaft must be free of oil. Idler wheel, must be oiled, and free of oil on the rubber part. The TT itself, must be free of oil in the area the ideler wheel touches it, and the shaft needs oil--- I ( as well as most motor makers), recommend 20 wt. ND oil be used in all oil points. IMHO, in NO case, should you "adjust the length" of the spring !!!
In RockOla's (RO) case, I find it necessary to use only the RO specified, (off) "white" type grommets. These are available from any one of the above listed suppliers ( See above--"Parts--where to find--").
One Caution about RO's: They had a couple of ways of mounting the motors. If you model has "e rings (aka: "sirclips"), and flatwashers, holding the motor, dis-regard the following. If mounted any other way, you should have small brass inserts inside the grommet. These tend to "fall out-get lost" when working in this area--do not let this happen !
Should you still have problems--new wheels are available, or you can have you old wheel re-surfaced.
On company doing this, I know of, is: Vintage Electronics.
