830 engine questions

Got the engine for the 830 out of the tractor. I already knew the engine was stuck.

Two of the rod journals are at a place where it's nearly impossible to get to the bolts. Obviously I can't rotate the crankshaft to get them to a better position.

I have the cylinder soaking in penetrating oil, in the hopes of loosening the pistons up.

Any suggestions on how to get those last two connecting rod bolts out? They are on cylinders 1 and 4. The connecting rod bolts for cylinders #2 and 3 are already out. So far, other than the stuck pistons, the engine looks ok!

Thanks in advance.

The engine in Dad's 800 combine was stuck after sitting for 18 years, it must have been in the right position, I didn't have any problem getting the rods loose so I could drive everything out the top of the block. I would think you should be able to get on the rod bolts somehow even if you don't have the right tools & have to borrow some. Been too long since I seen the bottom end I don't remember.

I would think you have the heads off. Pour about 1/2" of gasoline in each cyl. Tie a 2' wire on a small rag and soak it in diesel fuel. Light the rag and use that to ignite the gas in the cyl. Make sure it is outside so you don't smoke up the shop. Only the fumes will burn off the liquid and it will burn for quite a while and warm things up quite well. When the gas is all burned out take a wood block the size of the piston and take turns hitting the two pistons with the wood block and a 3# hammer. The heat will loosen the piston in most cases. This works best if the piston is 1/2 way down. LOL
