How much is a new stitch length cam? I've never had a main shaft out...is that straightforward to do?

$75.00 w/shpg.the shaft can be hard to get out you need to sand it lightly as it gets rust & dirt on it.Then oil it so it slides out easier.

I would get a wire brush and scrap all round the unit particularly around the feed eccentric seam and then add a few drops of good old fashion diesel around the feed eccentric seam.

A few hours sitting with a few drops of diesel made a difference! I'm gonna throw away my penetrating oil 😜

I've got 2.5 turns each way now. How many turns should I expect when it's fully loosened up?

I'm glad the you got it freed up. As far as I'm concerned there's nothing better then good old fashion Diesel. It works better then any of the "penetrating oils" just smells a bit. I would now flush/soak the area with synthetic transmission fluid. That will soak in and flush out the old garbage while lubing.

Sorry, can't help with the amount of movement you should have.
