Dare I mention preventive maintenance?

We could all take a tip from the vintage radio crowd. RECAPPING

As part of the 'refurb process' on these machines, we can simply replace the capacitors as standard procedure - regardless of if they work or not. If they do work, they are old and likely to fail anyway - so while you have the machine apart replacing the drive roller wheel, take it a step further and avoid a failure in the near future by replacing them now.
