Deere 2305 Cylinder Head Cracked - Where can I find another one?

papatractor · Jul 3, 2013

My 2305 cylinder head is cracked and I need a new head. Yanmar 3TNV76 engine. I have searched the web for new heads, but it seems like Deere is the only one selling them. I would like to buy new or used. Any suggestions?

Thanks,

Welcome to the forum

Did you check with this place?

Cat - Cummins - Mack - Detroit Cylinder Heads

I have not dealt with them, just found them in a search.

They are on my list to call after the holiday. A search of their website did not turn up anything. I would like to figure out the Yanmar part number and try and find one that way. Struggling a bit to figure that out.

You price one from JD yet?

Oh yes! $2,000

What is a whole engine then?

Why did the head crack?

My son was mowing and let it get too hot. They are known for getting grass over the screens. I wasn't there, but I can only speculate he ignored the little red light and ran it into the ground.

The engine is $4000. There are some used ones for $2300. There are only 200 hours on the tractor.

My preference is to replace the head.

Is the rest of the motor okay?

Seems to be. I did not see any cracks in the block. It would start and run. Just hard to start and then would blow out white smoke. Not visable leaks. The crack is between the valves in the middle cylinder.

I'd suggest taking it to an automotive machine shop first, if you haven't yet.
There is a reasonable possibility that you will need a new head, but the machine shop may be able to weld up that cracked head
after checking to ensure it is actually cracked (and if it is cracked, the full extent of the crack). You might just have a warped head.
Even if you can't salvage the head, you can strip the parts and buy the machined casting, which should cost considerably less then the built up head from Deere.
As far as finding another source....Yanmar engines are used extensively for industrial and marine applications. Don't limit your search to just tractor related sites.
