While waiting for AF parts including the vulcanized rubber wheels (at $22 a pair) I decided to try something.
I took off the most offending traction wheel on the front truck.
I peeled all the rubber off the wheel and face of the wheel which really was not that hard to do.
I sanded the wheel with light sandpaper and then emery cloth to finish.
Next, I choose the best fit rubber traction tire I could find and used epoxy to glue it on the wheel.
The four small marks on the wheel at 12 -3 -6 and 9 are little indentations with rubber in them (not sure why this was done). I left these indentations with the rubber in them and put a little epoxy over top of them.
Next step was to clean everything up, re-install the plastic bushing and place the wheel back on the axle.
I allowed for horizontal leeway with the wheels but closed the gap a little on all the wheel sets.
Works like a charm.......even the wobble is now gone......straight and true.
Very nice to see.
This was not near as difficult as I feared it might be. Quite easy actually.
So again I must wonder why was it necessary to vulcanize rubber to the wheel face?
