TrainMan1225 posted:Borden Tunnel posted:2102 photos were posted 4/20, looks like a lot of heavy rebuilding which confirms my thoughts that this engine was really beat.
I figured that too. I believe the last time the 2102 had any major work was during the time she spent on the Reading. Check out this video from 1991. I wouldn't be able to tell any boiler problems just by watching, but the rods seem to exhibit a lot of clanking, so I think those will need to be re-machined if they haven't been already.
"Clanking rods" are not necessarily a sign of wear, especially if you hear them when the locomotive is just drifting. The last thing you want is no noise, because that would mean they are too tight and the bearings would overheat. Roller bearings, yes, they should be quiet, but not plain bearings.
A certain individual had new bearings made with tighter specs than the factory for a certain locomotive. It did not work out at all, what a surprise.
Also, a little "slop" is good for going around tight curviture.
Rich, Jack, and others can give you much more information.
