2 forum posts	Hi I have a ML 7 trileva with qc gear box; the top selector never worked well, this is the one which selects form a /b not the lower gear selector. It has a grub screw on top to the right of the gear box. I looked inside and the plunger is missing ; myford do not supply this . Can anyone supply a picture so I can make something to work ? thanks in advance

The lack of the detent pin will not stop the selector working. I you cannot locate the diagram, or find one on an internet search, pm me. My selector was sloppy, and was fiddly to use, turned out to be a loose screw. Remove the cover from the gearbox and check the sliding gear works. Peter

The sqare part fits into the movalble gear shaft below it and the round pin on the top of the Square is a fit in the 193 A2272 Quadrant Plate that is moved by 197 A2511 Upper Lever. All part numbers are the same on QC Gearbox for ML7 and Super 7 Lathes When made the part is a snug fit with between the Quadrant and Shaft location.
