Ford 4500 seized engine/clutch

[avjz79]

Acquired a 1966 Ford 4500 that had been sitting for 15 years and found the engine locked up. Went to pull the engine to free it up and found this. 25 years in the automotive industry working in the rust belt, I have never seen something this frozen before .This engine was the hardest I've ever had to separate. The clutch was badly seized to the shaft.

I'm curious how you got it apart. I once had to use two bottle jacks to get one separated.

Wrapped a chain around the hard nose and attached the other end to my Chevy 2500. Kept yanking and after every pull had to Re-adjust my lift points and jacks because it was ripping the whole tractor forward. Finally the clutch broke and it separated after a tough 2 hours.

It looks like it has set in water.

I tell my customers all the time." Sometimes you have to break things to fix things."

I see it has the grease line going into the bearing. A lot of good that did. Is that the early 4x4 manual reversing trans?

I did a 3400 for a customer a few years ago but it wasn't quite that bad. Mice had made a nest in the clutch housing and the only opening for them was the timing cover plate being missing.

Assuming you got the tractor for nothing.

The grease line is just for the throwout bearing. It certainly does nothing to keep the splines from rusting.

Yup, it is the 4x4.

Yes. It has the 740 front loader and the 755 backhoe. Hydraulic hoses are not in great shape and the controls are all seized up for the backhoe that I don't know much about so depending how much the engine needs I may just ship this to the scrap yard down the street.

Before you do that, consider advertising on a few forums. Explain what you have and what parts and pieces are still usable. You might get more for it in pieces than scrapping it out. People are always looking for parts.

I had to do the same thing with my F150 to get the clutch disk off a Jubilee!

Got the pistons out tonight and everything is checking out good, so it looks like I can just throw some pistons,hone the cylinders, and get a new clutch kit to get it up and running again so the saga still continues

Great minds think alike!!!!

My 4500 was in bad shape, but if you can do all the labor it's not expensive to rebuild (like I did mine).

I've seen this on YouTube when doing research! I appreciate you posting it! I have an automotive shop so the labor is cheap . Just ordered all the parts so should have it running on my engine stand by next week. Was it difficult going through the rear backhoe controls at all? Mine are frozen and never have dabbled in hydraulics before. Hopefully can just clean it out and get lucky and free it up with some rust penetrant.
