When I bought my very old lathe (rebuild in 1967) the pulley was worn out. Thought it would be an easy fix to solve that but cause it's such an old motor the driveshaft is 23mm instead of the usual sizes. So it took a very long time until I found someone who could make a bushing with a 'keyway?' for the worn out pulley. They made it for me at a technical school so very greatfull to them! Had some work to make it fit and secured but it's working fine now. Now I only have to replace the belt but that's a lot more difficult then I imagined

. Cant't find a manual or technical data anywhere on the web but as I found out, I have to take the upper part of the lathe appart to replace the belt

. Read a bit about 'nut-t-link' v-belts but they're only for using in 1 direction and not suitable for alu pulleys. So think I'll go for the long run and dismantel the needed parts, check the bearings and go for a normal v-belt as intended. Strange that it needs so muchs work to replace a wear part.
