S-O-S Overhaul

A close friend of mine has damaged his once excellent S-O-S transmission (671) by running it out of oil, and he wants to have it completely overhauled. I do not have the time to tackle this project within his time frame.

Anyone know of a competent S-O-S mechanic in the Midwest (SE IN). He may be willing to travel a bit or ship.

(quoted from post at 19:47:27 07/23/16) Just curious , what would an overhaul on a SOS cost?

Basically depends on what needs overhauling. Total overhaul, likely in excess of $2500.00

I guess as I contemplate this, I'm wondering how he damaged it or thinks he damaged it? Maybe he could have been hard on the pump if he ran it long enough, but everything else would have quit when the pump ran out of oil.

I'm 120 miles west of St. Joe, MO if that helps any.
 
I was not there and have gotten all information third hand.

The tractor once belonged to my close friend but now belongs to his brother.

My friend tells me that he started it and it would not move. Apparently they knew that it was leaking oil because they immediately checked the oil level and it held 2 1/2 gallons. It still does not move (not traction disconnect) and "makes a noise." The PTO does not work either.

I suppose it could be a torque limiting clutch failure coincidental to the lack of oil issue. I have not seen it and the owner has not yet called me.

I replaced the interlock pin on this tractor a few years ago after my friend bought it from a neighbor for $1,200. The local CNH dealer would not work on it and told the PO to get rid of it. The seller/neighbor was quite upset with the dealer after finding out that I had repaired it for nominal cost without disassembly.

The tractor has a "nearly new" input shaft in it replaced 15 or so years ago when one could still buy them. It has been used little since.

When the owner calls me, I will advise him to split it to check the torque limiting clutch. He may get lucky. If not, he will want it rebuilt.

Aside from this new issue, it's a very good 671.
