OUCH!Search the thread "unintentional con rod inspection port"
I started a new discussion on the same tractor.
..... the final result is that the #5 rod big end h as d apparently been knocking for quite some time and finally made itself known to the outside world through the left hand side of the block.
I am discussing what I may or may not do with it on the other thread.
I was hoping the crank would be serviceable without machine work... but it's pretty beat up. I'm now considering just making it a 5 cylinder.

Why?I'm not sure turning it into a 5 cylinder is a realistic option.
This is false. We have 2 4430's that we swapped 7700 engines into. The block casting numbers are the same.Combine and tractor blocks are different. Tractor block is much heavier because its a stressed part of the frame.
