Stuck clutch – Mk2 Super 7

[Adam HarrisParticipant @adamharris13683]

Michael, I have aluminium soft jaws on my vice – would that work or would that damage the thread whereas copper soft jaws would not?

All sorted now. I removed the countershaft with clutch plate attached, gripped the thread in the aluminium jaws of my vice, twisted the pulley assembly to slacken of the push rod, then put the countershaft back in the housing locked in place with the circlip, with end blocked off by clutch lever in situ, released the push rod and spring completely, removed the countershaft, knocked the clutch plate out and cleaned it up (edges a bit gummy), reassembled back in the countershaft housing without the clutch lever in situ, partly drilled a square hollow bar to seat the end of a 5" rod pushing the push rod in, attached 2 G-clamps to the square bar either side of the push rod, and gently pushed in the push rod to the correct thread position turning the pulley by hand to wind on the thread, then some more in order to be able to be left with enough room at the clutch lever end to slide the clutch lever back in, then reassembled and slackened off the thread to correct position. Very simple really. The key really was the use of aluminium (or copper) soft jaws, and the understanding that the uncoiled spring still stays comfortably within the countershaft to enable easy recompression

This thread has been a great help , I have managed to purchase a super 7 at a silly price and the nut and the locking bolts are missing ( along with the tail stock saddle and motor ) great project
