Spindle removal

3 forum posts | Hi I have just bought a ml2 for a restoration project and I want to strip down the headstock, I have removed the grub screws from the pulley and bull gear and removed the threaded collar on the left hand side and undone the top clamp screws, with a soft mallet I tapped the left hand end to drive out the spindle , it moved about 5 mm that’s all, any ideas please |

3 forum posts | Roy i have checked and there are no more grub screws in the holes, the large gear wheel spins freely but the pulley and small gear does not spin |

Is there by any chance another grub screw in either of the holes that you have removed one from ? Spot on from Roy . On any old machine always check for a second grubscrew. Clean anything that may conceal a taper pin and touch it over with a marker pen, wipe the ink off and look for a tell tale mark is another regular check(not your problem here though I guess). |

![]() 1891 forum posts 37 photos | I had problems removing the spindle from my ML2. The issue turned out to be somone had tightened the pointed grub screw in the bullgear away from the intended recess and raised burrs on the spindle. not much you can do about it other than brute force or miving the spindle / gear positions back to where they were and using some kind of long end cutting tool down the grubscrew hole to remove the burrs.

Robert G8RPI. Exactly this. I had the same on my ML4. George B. |
