Kubota L3130 Engine Problems

[BakerMike]

So finally got a chance to tear into it more, a few bent rods and a lot of carbon build up in the cylinders. There is some scarring on the cylinder walls, it looks to me like whoever owned this before never took care of it (possibly one reason for the broken crank). I went ahead and got a new motor shipped, should be here in a few weeks.

I would be checking the intake system for a cracked hose or something allowing air to bypass the filter. Also if it is possible rain got into the cylinder(s) causing a hydraulic lock when cranking.

Mike, Where did you get the new engine?? Is it a reman or NEW.??
Do you have to send the old one back??
I could use the inj. pump off of it, if your gonna scrap the motor..
How about price, was it reasonable?
Is the neighbor gonna "kick in" on the cost??

The only thing I can think of is, the engine has had a coolant leak into that cylinder . Possibly because the head bolts were not re torqued after the apparent rebuild by the previous owner . That piston may have had water/coolant on top of it when it was started, which bends rods and can also break cranks .
It may have even ran like that for a while, without the front pulley and fan turning if the operator hasn't got an ear for things .

I got a reman engine from a place in OH. From the sound of it though I won't get much for the core if I do send it back so I will probably just keep the old motor. I believe the reman has everything but the starter, flywheel, etc. If that's the case I'd be happy to send you the inj pump. I'll update in a week or so when the new one gets here. As to the cost, with the core charge and shipping it was just under $4800. Neighbor has agreed on paying half so not too bad.

That's GREAT NEWS on the neighbor helping out..
Yeah, I'd love to have that pump for a core & parts.. they're getting harder & harder to come by..
I was doing 1 last week & needed 2> .50 parts.. because the customer took it apart & lost them..
They had to come from Japan w/ a 2 WEEK shipping time & I HAD TO buy 10 each.!!!!
FOR 2> .50 CENT PARTS.!!!!
