Stuck engine: what next?

Postby clintmo » Sun Mar 06, 2016 4:20 pm

I got some time to mess around with #4 today. I freed up several stuck valves, hoping that would get me somewhere. It didn't. Still locked up tight. Does the head need to come off now? I'm pretty clueless here, so speak slowly and clearly. :wink:

Thanks,
Clint

Clint, remove the starter and see if you can get the motor to turn backward by prying on the ring gear. Also check to make sure the fan is not froze.
It is common sense to take a method and try it. If it fails, admit it frankly and try another. But above all, try something.

Check for a stuck fan and loosen the starter. Also check to see that all valves are free.

I'm not a fan of prying on the flywheel ring gear.

Suggest removing the spark plugs. Putting 2 or so tablespoons full of solvent on top of each piston.

Tractor in 3rd gear, periodically, once or twice a day, using a rear tire rock the tractor forward and backward. Check the engine fan for movement.

Patience. Every 2nd or 3rd day add another tablespoon of solvent to each piston. Continue to rock the tractor. Give this a try for a full month. If the engine doesn't free up then we will need to remove the head and take more drastic actions.

If the tractor was running when parked (really running) then the normal problem is piston rings stuck to the cylinder walls. But there could be other problems causing the stuck engine. Could be carbon jammed between a piston and the head. Solvent will loosen the jammed carbon.

If the tractor wasn't running when parked there could be a problem with the hydraulic pump gear or at the distributor or idler gear driving the distributor.

While waiting, prime the oil pump, several times.
I have an excuse. CRS.

I did what Eugene said and I got mine to free up. Keep at it but be patient.

What do you guys prefer for the solvent? Kroil? ATF/Acetone mixture? Other?

Some free up easily, some don't! I had several free up, with Kroil in the cylinders, for a few weeks. Several needed a hydraulic press, pressing on a wooden peg on the piston. (Crankshaft removed,each piston pressed individually. Clean and hone the bore, above the piston, and it usually comes out easily. Ream the ridge, if there is one)
Also, made a short "crank", a piece of rod, with a cross pin, to fit the front pulley. Weld a big nut onto the end, and use a long breaker bar, or a pneumatic wrench, to turn it.

I was not very disciplined and tried a number of them on the stuck engine including the home brew. Not sure which worked. I do like the acetone/ATF home brew. I have used it on items I had little hope for and it worked.

I've had no success with the acetone/ATF mix. I wish it would work, for me, because I'm cheap, and it kills me to pay for Kroil, but the Kroil works, for me!

I had a WC Allis Chalmers engine that I never did get unstuck. Engine had been full of water for many years. Did the soaking in solvent. Removed the head and put a 2X4 fit to the cylinder and hydraulic jack pressing down on the piston. 6 month later I gave the block and innards to a guy who put the engine in a barrel of waste oil.

Then purchased a complete unstuck WC parts tractor.

There may be hope, depending on how stuck the engine is.

Haven't had one, yet, that wouldn't unstick. 12 ton press, was the most force I've used.

Alright. I can be patient with this one. All the valves are now freed up. It's a really funky mess in there, more so than you would guess looking at the tractor. The fan turns. I'm not sure how long it has been sitting, but I get the impression it wasn't stuck when parked. I only discovered the stuck engine after I got it home (rookie move.) The PO seemed genuinely unaware of it.

I'll report back with any updates.

Thanks,
Clint

A Barnyard Bash project perhaps.

I have two others, each with a laundry list of their own, both in line ahead of this one. I have no shortage of projects!

Ed, He keeps coming to the Bash. I think he is catching on
