Ford 3000 won't crank to start

[rwridle]

Could it be hydraulically locked? Will pulling the injectors help?

Sorry- guys but if the crankshaft can't be moved with a pry bar there are bigger concerns but the starting system will have to be dealt with eventually.

That sure sounds like a SUPER LOW hour 3000

I updated my quote here.

Yes, as Texasmark said

Pulling the injectors would remove the possibility of hydro-lock of the engine cylinders If it is a stuck piston the acetone /marvel mystery oil/ ATF sounds good to me

have to admit I am a bit stumped ... a good running low hour Ford 3000 diesel just slows down and locks up with No odd noises or white/blue smoke...

Just to be clear- a fair amount of force was applied to the ring gear with the pry bar and it did not move at all not even a little?


Wish there was a way of eliminating the pto from the equation short of splitting the tractor. Didn't you say the PTO can not be rotated when it is disengaged???

Other low cost things that can be checked
For a little labor and gasket replacement cost You
could pull the valve cover and inspect the top end for bent/broken parts and possibly pull the oil pan and check that the rods will move a bit side to side on the journals and maybe check a main or rod bearing by pulling a cap or 2 you can also see up into the cylinder bores
pulling the stamped pan on a 3000 is not to involved.

Sorry nothing really jumps out on this one , From the video that Is a Really clean Very nice condition 3000 - worth fixing for sure.

Thanks again guys for the feedback! I did not try to rotate the PTO by hand and will check that. I will pull the injectors and use the acetone/atf treatment.

I have been unable to budge the flywheel with a crowbar or turn the engine with the crankshaft pulley or fan belt.

Another symptom is it started blowing black smoke from the exhaust and from under the front of the motor. There was never a clunk or grinding noise, so I hope there is no major mechanical damage.

I hate to say this, but I think your oil pump has failed, and that's why the engine seized. think about it, a fine running engine slows down, then eventually seizes, without any noise.. if the crank or a piston rod broke, you'd hear that!..

I agree. I will provide updates as the situation unfolds. Thanks again!

Could be,
that was my thinking on the very low hours on this tractor - it is still likely a really tight engine and those 3000 cranks are huge for the displacement of a 175 cu engine- they weigh 77 lbs
Journals are larger than many big block American V8s
Loss of oil pressure with large surface area journals could lock the engine. Or just installing a cam bearing without lining up the oil hole
More digging is needed for sure

The black smoke right before the engine stopping could have been from the injection pump injecting more fuel because of the governor was trying to maintain RPM's against whatever caused the increased friction.

Still hoping for something simple and not expensive.

I think I found the problem: blown head gasket with water in the engine. See attached pictures of injector port #1 and the corresponding injector. Should the injector body be rusty and pitted?

The actual seal for the injector to chamber is the flat washer (at the bottom ) - so the injector body can get a bit rusty from water getting down the injector bore.
But if there is water/antifreeze in the cylinder / piston relief itself then that is a problem.

Is the crankshaft able to be turned now?

 

[rwridle]

Couldn't turn it after I removed the injectors, so am treating with acetone/ATF I will check it this Saturday.
