Stuck 460 diesel engine

tntleake · Aug 1, 2010

I purchased a 460 diesel that has a stuck engine.
I pulled the glow plugs and put PB blaster in there for about a week. I raised one tire and rock it back and forth with no luck. hooked on to it and pulled it on pavement and it just slides tires in 4th gear. I then tried brake fluid and the same results. I have removed the oil pan, which was slightly dented in the sump to find everything looks good below.
Any suggestions on where to go from here.
Oh and when I drained the oil, I found no water!
Thanks for any help

you need to pull the head and look in side

Stuck diesel turpentine is the way to go BTDT. As for pulling one that is the best way to brake things. Use the starter with the glow plugs out and if it is going to free up it will in a week or less of soaking

next step, pull head and you will see why engine wont turn over.

Dont do something stupid like using the starter if it is stuck bad. Pull the head and soak the piston, then try to turn the engine backwards, this way you are not trying to push the piston rings past all that rust. Then hone the cylinder and your good to go, that is unless it is really bad and you need a new sleeve.

As you're standing in front of the tractor facing it, the engine turns clockwise.

Don't get impatient!

You only soaked it a week so far. Sometimes it can take 3-4 weeks, maybe months, of continuous soaking to free a stuck engine.

Penetrants take time to work. People will squirt a rusty bolt with PB or Kroil, then slap a wrench on it right away, and wonder why it won't move or twists off.

That said, there might be more wrong than just a stuck engine. Diesels don't generally seize up from rust because the fuel is actually a light oil that makes a great rust preventative coating.

Any idea why it was parked? If because the engine siezed up, game over. Time to tear it down.
How was it stored? Outside with no cap on the exhaust? Again, game over. There is so much rust in one or more of the cylinders that it ain't coming loose in 100 years.

I vote for pulling the head. I'd pull the injection pump off too. Some diesel pumps get really expensive when stuck parts get twisted off. I drug a C Allis Chalmers home once that was stuck. Pulled the head and found a mouse nest in #2.

The tractor was parked out side, but in the Arizona desert between Phoenix and Tucson. It has a rain cap on it. and three was no water n the oil. It has been parked for at least 7 years and the starter failed as the original reason the tractor was parked. The starter was not in place but came with the tractor. It spins on a battery, but won.t budge the engine.
