Stuck Touch Control Lever on Super A

Postby AllanD » Tue Mar 10, 2015 8:23 pm

Sorry for the new post so soon but I thought it would be better to start a new thread for my other problem. The left Touch Control works fine but the right wouldn't budge. I disconnected the rod and the rock shaft works fine when I move the control rod so it is in the lever assembly. I took the assembly off and got the right lever loose from the shaft with some difficulty. I had to drill out the roll pin holding it on. I then removed the C shaped spring retainer. The shaft still wouldn't move. I applied a lot of penetrating oil and my super penetrating oil of Dexron and acetone but still could only twist it a few degrees. It looked like it should slide out to the right but I couldn't move it even with a slide hammer. Then since it would twist a little I put more force with a wrench on the end of it and broke off the L shaped piece on the end that hooks to the control rod. I'll have to weld that back on this weekend. So either it is real stuck or I am totally mixed up on how it is supposed to come out and screwed it up. In my parts book the shaft appears to be #23 in the drawing which is: part 354 751 R11
Anybody know how to get this piece out and loosened up?

Mike, good point. The black areas are where I applied a butane torch to it. Maybe I need more heat, do you think I need oxy-acetylene? I wasn't sure what the piece was made of, I have heard that you need to be careful with high heat on cast iron but this may be cast steel. Would you heat it all the way to the point of it glowing red or is that risky?

Shouldn't need too much heat. I just use a propane torch on everything. Doesn't take much heat to cause expansion, which is what you are aiming for. Like I said, soak the thing in PB Blaster\WD40 or any other penetrating oil and then torch all the areas but the rod. You want to expand the metal around it, torching the rod itself won't be as effective.

To catch up on this issue, I can say problem solved. I ended up using my slide hammer but made an adapter to fit on the end of the shaft. I'll try to post in the how to but I think patience for the oil to work was a significant asset. After I got it all cleaned and lubed I welded the arm back on yesterday. Thanks for all the help.
