You might be able to use a Dremmel type tool to split the bushing to remove them, however the 3 service shafts I restored had the shaft area worn down significantly. So you will probably need to remove the levers and build up the shaft ends (weld them) and dress them down. I have done all three shafts by welding up the bushing area and it isn't too bad of a job.
