401a problem
I've been working on a 401a for the last couple of weeks, off and on. It appears that the machine was barely used, but kept in storage, face down, for quite a while. (lots of goo on the face, dirt on the back of the machine and the legs have lost their finish at the bottom) All of the gears were dry and everything turned really slowly, if at all, so I didn't try sewing with it. The only thing that appeared to still have lubrication was the cam stack, which had lots of black goo on it.
I've cleaned it well and lubed it and it's turning nicely and has loosened up significantly. The only problem I have left is the knobs that control the cam stack. At first, neither index pin would move. Finally, T3 moves. W3 won't budge. Is this a hairdryer situation? I put some more oil on it and am leaving it overnight.
Any ideas?
