SP&S 700 Test Run

Rebuild the power reverse.
Remove rods for bearing inspection and conduct precise tram measurements.
Rebuild the feedwater pump.
Replace the tender's wheels with new ones and the bearings with new Timken sealed AP bearings.
Remove and inspect pistons and rings.
Replace all the brick in the firebox with brand new firebrick.

track out to Hillsboro and back. We are very pleased with the results and are now turning to the final
preparations prior to leaving for Montana in little over a week.
