My Schaublin 135 needs new belts, they've stretched and worn and an oil leak on the countershaft hasn't helped. My machine is fitted with a lever type collet closer which doesn't feature in the manual. Followed the instructions right up to the point of exposing the main spindle pulley, but the body of the collet closer is in the way (See photo attached). I can't see any obvious way to remove this part. It has a split collet clamp affair around it, but it has no split's in itself. There are 4 slots machined around it under the split ring, but with a drift it hasn't moved either way. I have a proper C spanner of the correct size but it's at work in my tool box. On the diagram of the ordinary machine I think I can see what it's located on, but unfortunately it gives no indication of whether it's threaded or not.
Anyone previously stripped a Schaublin 135 to change the belts?
