good day all i have a problem with a case 830 case o matic. i got this gave to me and the motor was stuck. the tractor had a small amount of water in the oil when i drained it. i am trying to figure out how to unstick the motor. there is no way to pull the tractor since it has a hydrolic cluch. i cant find any where to put a wrench on the front of the motor. any ideas? thanks

I have not done this on a Castomatic but have used the technique on several stuck tractors. Put the transmission in neutral and engage the power take off. Next put an old coupling on the power take off shaft. Then I use a pipe wrench to twist in both directions. Take it easy on the force.

I am reluctant to use the hydraulic method for fear of doing damage. If more that one piston is stuck and the one you are working on breaks loose, the remaining stuck piston then gets all the load. I know of folks who have damaged rods this way. Also, it is relly hard to gauge the amount of force you are appling using this method.

The secret to freeing stuck engines is to be very patient and relly watch how much force you apply. The old soak, apply force, soak again etc will eventually work.

I would appreciate any comments on my suggestion from others.

If its a gasser, take an old spark plug and use the method on one of the posts by Tom Railsback or Don livingston, can't remember who used this. Diesel I am not sure of but would take an old worn out injector. Basically gut the plug and drill through it, Weld a pipe nipple to it and connect a hydraulic fitting. Fill the cylinders with penetrating oil and let sit a week or so. One by one in a full cyliner screw in the modified plug an hook up another tractor's hydraulics and ease on hydraulic pressure until it moves. If no movement, let pentrating oil sit longer and try again. Also search archives for unsticking engines and you should find the complete instructions. It sounded like a good plan to me and perhaps someone will chime in and post this procedure. I think it will work.

Hi Jim ,,,I think that method is John Saelis ,, And it does Work ,others give testimony ,, Last fall , I freed up a VAC after many monthes of soaking with kerosene ,ATF and diesel Fuel ,,, backed 430 to VAC Attached a 540 splined Power shaft , With 430idling , VAC PTO engaged and Clutch Pedal Blocked down , Dumped clutch momentarily Back cranking / then starter cranked FORWARD ,Stopped after 5 minutes . always got a little movement .then topped off Spark plug holes .After a week of trying once a day , VAC broke free ... The 800 should be straight thru to PTO , and this may work , If it were Mine I would engage clutch pack on PTO and keep it engaged , And Bounce the PTO clutch from the RunningTractor . Hand clutch DC or SC is perfect for the job . I would NOT RECOMMEND PUTTTING A LOT OF POWER on IT ... let us know how you come out ...

take the starter out you can see the flywheel starter ring gear teeth use a pry bar to turn the fly wheel Jerry

Today's Featured Article - Uncle Cecil's Super A Lives Again - by Mike Purcell. A week or so out of most of my childhood summers was often spent with my Uncle Cecil and Aunt Sissie in the small East Texas town of Maydelle on their 80 acre farm. Some of my fondest memories of these visits are those of learning to drive a tractor at the helm of Uncle Cecilís 1948 Farmall Super A. Uncle Cecil was the second owner of this wonderful little tractor, but it was almost as though he had adopted an infant. The original owner was a man from Minnesota who bought her from a local dea ... [Read Article]
