I have found that the only way to resolve it with any degree of success is to clean up the spindle and the plastic cup then glue it back on to the spindle with Araldite. By far the worst offender for this problem is the Hymek. All four of mine have suffered drive loss from either one or both bogies requiring the above solution to be administered. Purchasing a new part from Gaugemaster is also a solution but then you run the risk of the same thing happening with the spare part eventually. Araldite has proved itself (on my models at least) to be a far more permanent solution to what is in fact a very irritating problem.
So I’ve removed the bogies and cups and there does indeed seem to be two very minor cracks on the bogie end of the cups. So you are saying to glue these to the spindles, by which i’m guessing these are the shiny metal parts that stick out from the bogie housing, right? Then just reassemble everything?
