I got everything set up and she is running, but I noticed two problems.
1. The right hand clutch release doesn't more far enough to stop the spindle. I'll move it until it stops, but then it will move again to the right and the spindle starts back up. If I use the left hand lever, it engages the brake and stays in place.
2. The carriage feed lever doesn't stay in place. When I raise it up to engage, the feed starts, but the lever slowly moves back down and starts to make a clicking noise as it comes out of gear
I will do more trouble shooting, but I was hoping that someone might know of what adjustment I can make to fix the problems.
It is possible that your clutch linkage is out of adjustment or time. The clutch linkage on the back of the headstock attaches by means of a taper in the shifting forks. You loosen the nuts and give them a tap and they will move. They are infinitely adjustable. If you take the control rod bracket cover off, there is a fork and a ball. This all must be in correct timing with the main clutch handle and the apron clutch handle. You must fool around enough that you see how it works, and then it will make sense. When it is operating correctly, the brake works well with little force and the clutch engages smoothly as the counterweight helps with the engagement.
In response to your second question, the longitudinal and cross feed clutches are adjusted the same way. At the handle connection points there should be a screw and a nut. You loosen the nut and turn the screw. It is an eccentric. With the clutch handle up, adjust the eccentric until it makes good contact then lock the nut. This is spring loaded and when there is an overload, the serrations of the clutch skip over each other and that makes a clicking sound. It sounds like yours may not be fully engaged. The clicking you hear is probably those serrated teeth.
If you are going to use the machine much, I would consider pulling the apron and the saddle and inspecting and servicing the oil system. It is a little bit of work but worth the effort not only in terms of machine operation, but it can also increase your understanding of what is going on. I’ve documented this in my Pratt & Whitney rebuild post in the Heavy Iron section.
All this assumes that you are talking about a model C.
