LEFT INSERT

This is what babbitt should look like when it sticks to the shell that has been tinned, and pryed out. The tinning was stuck to the shell, and the babbitt was stuck to the tinning. So the shell was Gray, and also the back of the babbitt of the pryed out shell.

RIGHT INSERT

This is what it looks like when the shell was tinned, but the babbitt did not stick to the tinning. This is the biggest cause of bearing failure. The back of this shell is the tinning turned cold, so there are colors left on the shell, and the babbitt.

It does no good the tin, if the babbitt does not stick to the tinning.

Notice when the shells are turned over, even the color is different to the out side.

If bearings come out white, you can just about say, the Temp's are all wrong.

So when you pried the cold shell out of the tinned shell that was cold then did the discolored shell maintain the discolor that we see on the first shell or did the right shell come out looking like the inside of the shell that you pried out of the left one that's tinned that turned gray?

Both shells were cold when I chiseled them out.

The Gray color is the back side of the tinning that was next to the rod metal.

Each rod is a color match to its babbitt shell.

The good rod and back of its shell are metal colored.

The bad pour is some Gray where it stuck, and some colored where it didn't.

Where ever you have color behind your bearing, it will fail.

I should have taken pictures of the Avery rods also, but I didn't think of it at the time.

Once the rod is cold, what ever the condition is when you pry it out, is what it stays.
