Well, most Freepers never do tell how these “help me thread” problems are resolved. No matter how many times they say they will.
I figure their wives must fix it for them and they don’t want to tell...
(Someone bumped that other thread.)
I fell you, if I'd resolved my problem, I surely would have posted that resolution to the thread.
In a nutshell, I tried about half a dozen of the best suggestions on the thread, and still was not able to free the bolts frozen in my machine. I even reached out to the manufacturer for help. Their chief machine tech told me that I'd already done everything he would recommend.
The consensus opinion at this point, is to pull the entire rear exit assembly and replace it with a new one. That's a repair that I absolutely CAN do.
Thanks for following up with me.
