Wow, $500 for a block sounds like a steal. Is your engine a 3304?
Yes it is! I am hoping to get the block picked up tomorrow and start the process of cleaning soon. I may do what you did and turn it yellow as I go.

That is the truth!!! I need to find a lest costly hobby!!
It's not a hobby. It's an incureable disease that many of us have. You can only get another fix to fix.
I claim metal (not mental) instability, does get in the blood and won't leave. Me, I am addicted to old Allis units, love the simplicity, ease to work on as opposed to most Cats, remind me of years gone when I worked them as new tractors. Cannot seem to stop working on the damn things regardless how bad it hurts the pocket.
Hey Guys,
I was following your progress,
I thought I would chime in, I am in the process of finishing a steering clutch on my 75 931. My first machine and I think I have Developed the FEVER also,
I have rebuilt almost all cylinders on the backhoe attachment and the loader, as for the motor mine has only 300hrs on a cat rebulid by the previous owner,
Its Interesting to me reading about your motor work, I don,t know much about motor rebuilding ,I just have general motor knowledge,
Thanks for documenting the work,
Hope it goes well,
Mike M.
P.S. This Forum is Great!
That must have been a replacement block then. It was originally produced on the 2nd of November 2000.
What's the Part Number at the far end of the photo..? All I can see is "2P9---"
That block is a Field Replacement for whatever was originally in the machine. So you have a hunk of iron in that photo that despite the fact that it's an "old generation" engine is nowhere near as old as you might think. For any Parts Service you need quote 1N-3574 Cylinder Block Group. This was fitted from engine S/N 78P57460-Up.
It's a direct replacement for the original. What happens is as things are improved then newer Part Number come into being. The Parts Manual will say something like "7N-6552 Cylinder Block Group. For Field Replacement order 1N-3574". So in other words the Field Replacement is effectively the newer improved version of what you had originally but is now beyond repair.
Your replacement block will be compatible with the former block, there may be a few detail differences in things like gaskets, seals, etc. You just need to be careful that's all. Also if you need any parts for the block then when ordering refer to 1N-3574 Block Gp. now you've "upgraded" you can't necessarily use the Part Number of the block that's listed in your Parts Manual.
