stuck clutch

wet weather and lack of driving has stuck the clutch in my 1941 1 1/2 ton truck, apart from removing the driveline, trans, pressure plate does anyone have any ideas on solving this problem. I though about pouring evap o rust in the clutch area, after sealing up the drain hole in the bottom pan and then turning the engine over to spread it aound. OK what are your ideas?
 
I for one would not pour any thing over the clutch plate as it may well impregnate the linings.
You could try towing in with a decent size tow vehicle in neutral and snatching into gear as you move.
I have had success in the past by starting the car in gear but these were probably not as stuck as yours.
 
does your truck have the removeable bottom on the flywheel part of the pan? ---if it does and trying to start --or drive with the clutch pushed down doesn't loosen it ther piece can be removed and a putty knife could be used to break it loose with the clutch pedal pushed down by going in from the edge.
 
I've found that blocking the clutch pedal in the released position for about a week will allow the clutch to "relax" and make it easier to break loose by starting or driving with the pedal depressed.
 
Jack the rear axle up high enough for plenty of clearance under the tires. Block both front tires. Start the truck in gear and let it rev up to speed. Push in the clutch and "bounce" the brakes.
 
so far have tried jacking up and running and pumping the brakes--stalls engine out
no pan to remove, recessed flywheel so you can not get a putty knife to it, currently blocked out , will leave for a few days, evap-o rust will not effect lining just the rust--to quote one source ( last resort before pulling trans) going to try making a suggested puller and try to pull on clutch plate spring holding plate, am also going to put against a tree and start in gear with clutch depressed--tried blocking front wheels--well let's just say it went over the 6" blocks, also going to run the truck around the yard with the clutch pedal depressed--FIRST will let you guys know the final outcome-thanks for the suggestions
 
You are better to Get out in a big paddock. Start her in gear, and drive her around. Keep in mind she wont stop unless you stop the engine.So give yourself plenty of room.
If you drive around, doing the brake thing, all the time with the clutch in, it's your best shot. They can sometimes take a lot to free. You might be surprised how much. Good luck!
 
I just had a stuck clutch in my 35 couldn't get it to free with rocking etc so I warmed her up in neutral towed to the highway then started in top gear and headed up the high way with clutch depressed and the gas pedal to the floor after about 1/2 a mile there was a big bang then the engine reved full noise yep it had came unstuck why not give this a try
 
You want to be at wide open throttle at the max torque band of the engine. So about 2000 rpm. in top gear, driving along, clutch depressed, on and off the throttle until it lets go. It will be an 11" clutch so it might just be stuck well enough to transmit full torque no matter what you try. Actually, might not be 11" if recessed.. Not sure about that.

Got to be worth driving and applying full load repetitively.

tub1/ mart-thats what I am going to do, have also been told to park on hill with clutch released and start engine and let her rip!!
 
been around the block a dozen times, stomping on the brakes and sliding the wheels, backed against a tree, spun the tires, currently hanging on a hill with a chain stopper, with my tractor tied to the front bumper for added drag--quess I will pull the driveline-trans and remove the clutch because it obviously has grown to like the flywheel and has stuck like GLUE, will be week after next before I can play with it, will give an update if anything changes, thxs for the ideas everyone
 
Block the clutch pedal down for the week you are waiting to get to work on it. Then try the above process again before tearing it down.
 
40cpe--that was my thought exactly, parked it on a higher hill, in first gear and have a 51 F5 tied to front bumper with a chain attached to a tree and I am going to leave it like that for now.
 
I tried everything possible, nothing worked so, everything was pulled apart, engine pan removed, pressure plate removed and then the clutch disc was pried off the flywheel--it was STUCK. After removal/ clean up, I miked the disc and a nos and a nosr and the original was still thicker. So it was re-installed and the pan back on, waiting till next week for some help to put trans back in.
 
I got lucky I had a 34 with a stuck disc. I started it in gear with the clutch pedal depressed and it broke free.
 
Alan, why do you think it stuck? Was it time and humidity, or did it get wet (fording a creek, washing it, something you did) Just wondered what you think.
 
bluebell, rain and humidity added to not being used for at least a couple of weeks. everything in my yard and garages was sweating from the high humidity. Got going and did not stop tonight until the trans was back in. going to do some work on the parking brake and change out a couple of u-joints before going back on the road.
