My manual feed J&S 540 is in need of a major strip and overhaul. I am having difficulty seeing just how you get the head lifting linkage off/apart. It is shaft driven like all others but it is very hard to see how you get the thing off/apart. If it makes any difference (and I don't think it does but anyway.... ) it has the plain bearing wheel head.

I also need to get at the motor to replace the mounting bobbins and short of getting inside (and I am too big for that) I can't see any easy/simple way of getting at it from front or back?

Has anyone any practical experience working on these things (particularly the head linkage/lead screw and rear mast assembly?

Well, not much response yet but anyway... It looks like the two bolts hidden under the thrust bearing support hold the whole thing together. I will drop the mast onto a support block inside and then release the feed screw nut and try removing the two bolts. There is another attachment on the top of the tube near the hand wheel that I could see from the off but it looks like it might come out reasonably easily. I think the key might be using a long prop to get the mast out of the way for tipping the screw towards the front of the machine so I don't need it over the pit to get it out.
