S Case stuck engine, ideas to free up?

Jeremy Lee · May 26, 2012

Just recently bought a S Case, unfortunetaly the engine is stuck. What are some ideas for freeing it up?

Pull the head to see the cycl walls then go from there if you cant pull the sparkplugs out and see in there. Theres a reason its stuck and nothing will renew the cycl walls without tearing down you can spend money on snake bite medicine and gain nothing so look into the cycls thru the sparkplug holes and go from there.

ive had decent luck soaking the cylinders with a 50/50 mix of ATF and acetone, just be patient, that being said if you pull a plug and it is all rust then there was/is water in there, might be a good time to pull the head, also just depends on what you are going to do with the tractor, keep it or just get it running to resell

A complete gasket set. You are dealing with a complete unknown. Do you really want to apply ever increasing pressure until something "moves? The broken parts will cost more than gaskets.

and D is right, but I did have some luck breaking them free. :wink:

Pull the head, it is only about a half hour job, real easy to do on them. You don't want to break any parts if you can help if because those Case engine parts are getting hard to find, I had to do a lot of digging to get valves and guides for my SC about 7 years ago.

I free up stuck engines all the time but I have also learned to read the signs that are there also. Thing like does it have water or other such things in the cylinders. What do the plugs look like etc. When I free up an engine I fill the cylinders with ATF and also pour it down the exhaust pipe till it leaks someplace and walk away from it for a few days. I then set a 12 volt battery on it and pull the plugs back out, always put them in to keep stuff out. I then use short fast taps on the starter to free it up. Out of over 20 engines like that I have freed up 19 or so

The most important tool.... patience. Then do what others have said below. I have everything working that was my g-grandfathers and had sat outside since 1959 when he retired. Patience, penetrating oil and heat.

Like the others said, pull the head. You probably have tight or stuck valves, so you tap the valves down and they won't come back up. Then you pry on them to get them back up and bend a few. Now you have to pull the head AND replace bent valves. If you pull the head right away you can loosen up the valves with much less chance of doing damage, and you can get to the pistons to soak/loosen them up if they aren't too far gone. I had to learn the hard way. Jim
