Thought I would see what ailed the excavator. Not what I wanted to find, but not unexpected due to the age. This is the #2 cylinder sleeve, and if you look closely, you will see it is cracked.

Is that sleeve easily replaceable, or at all?
Hope so.
Will an engine pull/breakdown, be necessary?

It is rebuildable. But before I tackle it, I may see what it would cost for someone else to do it. I can get everything needed to do a proper rebuild. Just need someone to turn the crank so we can put in properly sized bearings.

What about a rebuilt short block or engine?

They are available, but significantly more. That would be something the board would have to decide.

Mike,
Would you prefer to bore that one cylinder only and sleeve it or would you prefer to bore and sleeve that one cylinder and bore the others to match? Seems like any rebuild worth doing should encompass the full job. Just my thoughts from years of doing engine work.

We are going to do everything. You have to take it apart to do one or all. So it will have all new cylinder sleeves (they are replacable) as well as pistons and rings, new wrist pins, new bearings, all new gaskets, and a new oil pump since we will be that far into it. And depending on what the crank looks like, that may get turned as well. Everything accept the pump comes in a kit, so it saves a bunch of money versus buying everything separately. As for the head, it looked good when I took it off, but we might send it out for at least some valve work. When it is done, it should have all the power it used to when new, and will serve the museum well for quite a while.

Good luck, Mike.
Something else to do in the shop? this winter.
Will then be able to tear into TOM-north ROW work in the spring?

If you send the head out make sure it is magnafluxed to check for hairline cracks.

Is it flat? enough? or should it be planed?

Have had success welding when no head was available.

Just curious...when newest track is open past TOM siding, will trains go to EOT, back up to the siding, then via loco runaround  be pulled  back to Sheepscot?
Would be an interesting ride.

We will not run passenger trains down the Mountain until track is done all the way to the bottom with the run-around at the bottom.  The Mountain grade is on the order of 3% or more, which makes it hard to stop and get started again.  Better to be safe than sorry.

The only exception may be the railcar.  Due to it's light axle loading it could run north of TOM and turn if there's a fairly level spot with adequate side clearance.  The decision for a longer run will be made by the operating folks when there's enough track past TOM to be of interest.
