743 question

[tjc]

Tore my 743 down found 3 cylinders out of 4 with water in them cylinder 2 was 3/4 full, and the oil pan was overflowing when I pulled the dipstick. Cracked head or cracked block

What is your question?

Cracked heads are more common with these engines - especially if they are overheated. Take it to a machine shop and have it checked.

I take it the head gasket looked fine?

Thanks. I took it that he was telling us he had either a cracked head or block.

Yep head gasket look great

What is your question?

Cracked or cracked block or could it be something less obvious?

 

[Wayne440]

My guess is a cracked head, seems to be a common issue with some Kubota engines.

Easy to see cracked heads, look for a crack between the valves and the prechamber.
And cracked blocks are very very rare and they won't put water in the pistons.
Was it water or antifreeze?
If its straight water, did it freeze? Or does it have an air cleaner leak or exhaust pipe pointed straight up?

rst thing you check is the exhaust. Make sue no rain can enter through the stack.

It was antifreeze and the oil pan was full of antifreeze and oil as well, the head had a crack about an inch long in the valve port, I spent 86 bucks for them to tell me I had a cracked head that was obvious

 

[North Idaho Wolfman]

Yes that's a common issue with these engines.
You can get a new aftermarket head and new head gasket and you should be back in business.

Ordered a head yesterday, are the 1702 heads the same or is there a difference that would make them not fit correctly?

 

[North Idaho Wolfman]

There is 2 V1702 heads, IDI and DI, you have an IDI in your bobcat.

 

[tjc]

So unless it says di on it it's an idi when you order it

 

[North Idaho Wolfman]

No not really, some sellers don't know there is 2 differnt heads. Give me the listing and I should be able to tell you which it is.

 

[tjc]

Kubota V1702, V1702T, V1702E Engine head

 

[tjc]

Manufacture part number ‎15422-03044, 15422-03040

 

[North Idaho Wolfman]

That looks to be the right head for you.
