Update, I emailed Tiara and they only have the replacement parts for ACME Screw ( which I was calling the "auger" above in the thread), they do not have a replace for the ACME nut which is the part that needs replacing for me. I have looked at Grainger and some other local machine shops and no luck finding a replacement. So I am not looking into re-tapping the threads in the nut. Finding a TAP and the ACME thread size has been the challenge. I just ordered a ACME screw pitch gauge....but at first glance the taps I will need to rethread look very $$ for a one time job.

Any ideas or experience with this repair on the tiara 4000E? I am starting to think replacing the ACME screw config with a hydraulic cylinder might be a better way yo go.
