new/used/rebuilt engine needed for JD 4100

[coloradotrout]

Hi all. I have then frame split and the oil pan off. The center (damaged) rod and piston out. The piston is destroyed. The rod to me looks ok and the rod to crank bearings look ok to me. But I really don't know what to look for.

Does anyone know if the cylinder can be overbored and a liner installed? What else should I do?

If I put in a liner and the same size piston, would that cause an imbalance?

A bent rod would give you vibration.

Depending on what caused the damage to the piston, you could also have damage to the valve train somewhere, also causing you vibration.

I would take the block to a machine shop and let them measure the bore to determine if it can be bored out. If the damage is greater than the maximum allowable bore size then a sleeve can be installed. All three cylinders will have to be made the same size so if one needs bored out they all will need to be made larger.

Would that be an option? Maybe just bore and line my bad center cylinder?

On the phone one shop mention that if one cylinder is bored the others might change shape and would also need to be bored.

Going to have a couple mechanic/shops look at it

One opinion says space between cylinders is two narrow to machine for a liner. New block is preferred. JD block is $2700; JD short block is $4700. Thoughts on where to find a block or short block?

Search results for: '3tne74' (assuming they are in De Sota, that's about 200mi for me)

any others?

I guess at this point I'm shooting for $2500 to get the engine back in working order. Gut feel, $750 block, $750 pistons, rings, etc. $1000 labor.
