860 strange crank bolt

I think my 860 motor may have seized up on me so I am going to try cranking it manually. Only problem is the bolt is hard to get to and there seems to be an adapter specifically for this purpose based off the teeth on the bolt. Any ideas where I can find this adapter or whatever makes this task easier?

The bolt holding the pulley to the crankshaft should be a standard hex head bolt. Post a picture of what you're calling "teeth on the bolt". I'm guessing that it might have the hub for driving a front mounted hydraulic pump for a loader on the pulley and the hub might have a stub of a splined shaft sticking out. If that is the case, you can remove the hub from the pulley if you don't need it, and then you can get to the real crankshaft pulley bolt.

Pull all 4 spark plugs, trans in neutral grab fan belt, should be able to roll engine. If not, put pto in gear, put pipe wrench on pto... Easier to get to.

Before you do that..

Back story.. Why do you think it is seized? What happened?

Hand crank adapter?

Back Story:

I was bush hogging today in 1st gear and the tractor shut off randomly almost like I had stalled it out with the bush hog. It was immediately apparent that I had not stalled it though being that the pto shaft was still spinning freely when it shut down. When I went to start it back up the starter engaged but would not turn the engine over at all or even come close. I even ended up taking the tractor up a hill with my truck, let it get momentum on its own, and popped the clutch in 5th gear which just locked up the back tires several times.

Before this happened:

oil pressure was great
temp gauge was reading fine (although it was 100 today)



Game plan as of now: let it cool down tonight (will get around 70) then go try and start it in the morning. If it doesn't start then I will spray kroil in the spark plug holes and let that sit for a few days and try again. More than likely I will pull the oil pan just to see what is going on if it doesn't start after that. Then, find someone to fix it and just redo the motor as my schedule does not allow for something that intrusive right now.

PLEASE let me know of any other suggestions.

Before you do anything else,loosen the starter bolts,the starter drive may have bound up on the ring gear.that happened a lot on the Farmalls and Fords I grew up on in the 50s and 60s.

Yep! Hand crank adapter is what you're looking at on the front of the engine.

I also would second what Cushman said about the possibility of a locked starter. With your tractor in 5th gear, rock it back and forth as violently and quickly as possible. If that doesn't knock it loose, do as he suggested before tearing into your engine.

Pull the starter first....

Well I found the problem. Dropped the oil pan and the crankshaft has snapped at the 1st bearing journal.

Anyone have a new motor or rotating assembly?
