Big Motor Trouble

If it has a water pump.. water will be pulled from the rad untill there is no more.. that menas water should be pumping out the head till the rad sump runs dry..

What was the purchase price ?

I still am floored that this kind of equipment isn't protected against low coolant and low oil/ oil pressure related damage. This kind of protection probably would run less than $120 to retrofit and the OE would pay much less than that with their purchasing power.

When considering engine damage due to loss of coolant, one has to imagine where the water will be lost first. Generally the cylinder head is the first to loose coolant, since gravity takes it down and away (assuming in line engine with vertical cylinders). Loose coolant to the head and you overheat the valve stem seals pretty quick. If not replaced you may burn oil later even if the bottom end is good.

Head bolts will typically stretch from the expansion of the head and often the head will warp. Usually, the heard bolts should be re-torqued as soon as the engine has cooled and before running it again, but that is too late now. It often will prevent a blown head gasket, but not always.

Sorry about the tough luck. Think about adding some systems to shut down the engine if something like this happens again (before damage is done).

I would want a crate motor put back in mine. I would not go for the rebuild at such low hours. You are in a bad situation in my opinion, you don't want to seem like a jerk, but you don't want to get the short end of the stick.

My stance would be a completly new engine being installed no exceptions. Who knows what all went to heck when it got hot. They do a rebuild then 200 hrs from now something else shows up wrong that is a heat related failure. I would be scared of what they missed during the rebuild or did not do thinking it was ok.

my 2 cents

If it's a REAL full rebuild.. it should be no issue.. all depends on the engine.. whether it has liners or not.. etc. new liners, pistons, rings, bearings.. inspect and magnaflux the crank, polish if needed.. check the head and valvetrain and block deck.. if all that checks out. should be good to go.

I think I would opt for a new crank vs a regrind and os bearings.. that would be my one sticking point.. that it got a new crank if the old one was needng cut, and I was going to have non standard bearings on a 'new' machine.

I had my water pump fail on my Ford 7.3 on a trip. Noticed the white smoke trail. Pulled over, towed to shop, repaired for an appropriate price (?$900). Luckily it's been running fine since.

I was expecting needing an engine swap.

I think they should at least wire it so the horn goes on if catastrophic failure occurs.

Thanks for all the input. Well first of all there was a malfunction of the emergency shut down so Kubota is on the hook.
For a repair the complete head was replaced. Everything else was checked, ok'd and documented by the dealer for future reference.
Thanks again

the head was probably warped.. real common in overheat situations

I agree with mattman. At 30 hours with a siezed engine I would want a new engine under the warrranty.
