Oliver 1250A head problems

Flat · Jul 15, 2020

the head gasket has leaked in the same spot 3 times now. parts are hard to find for this model. The mechanic I had didn't think that the head was compromised.

I now feel that I should remove the head and have it inspected and shaved. there are 2 different head gaskets for this model, I am told. knowing which one I think could be troublesome for me. also, getting the right head bolts new may be a trick.

I live in sw washington, not the best country to find oliver advice or help.

Any comments, pointers or advice of any kind would be appreciated.

If its a 1250-A it'll have the 3 cylinder diesel, parts shouldn't be any problem to find or a used head.

(quoted from post at 13:11:53 07/15/20) If its a 1250-A it'll have the 3 cylinder diesel, parts shouldn't be any problem to find or a used head.

I forgot to mention it was diesel and 1968 2wd

so, where do I get the head gasket set with the new head bolts. maybe even head, if I find it is cracked?

The last time we tried this was years ago and we had a very hard time chasing anyone that knew anything about it. My mechanic was not very motivated, he is more of a parts changer. he just not very through and is out of that work now (health).

I have an old manual that is complete top to bottom on this tractor, he also got one out of it.

If you have had 3 identical failures just changing the gasket will not solve the problem!. Send me an e-mail and include your phone number. J.

I think we were thing it was bad head bolts. he checked it with a straight edge. I believe that I need to have it checked better. It ran strong even though it would blow some pretty black smoke at load. as soon as it leaked again, I shut it down.

Did you check the top of the block?

You said the mechanic didn't think the head was compromised. Didn't think might be the problem. Take it to a machine shop and have them check it. If it checks out ok then, I suggest you do some checking of the block. I had that happen with an Oliver 70. Block and head went to a machine shop. Milled the head but, he said the block was good. I don't think he checked the block. Put it together and started adding water and had seepage before the radiator was even full. Pulled the head and put a straight edge across the block. Found an .008" gap. Complete tear down of the engine and had the block milled. It's been good since.
