Wow! I have to give you a lot of credit. You drilled an inspection hole in your tractor! LOL. I don't know if I could have done that. But, you do what you have to do to get er done. I had to split an older model Ford tractor not too long ago because in all their ingenuity, Ford placed a freeze plug in the rear of the block and you could not get to it without the split. So now I've got a JD 790 with a stuck clutch plate. I have worries that I bought a tractor that had been partially submerged in salt water after a hurricane down here in Florida. Hence, a stuck clutch.
Just want to thank you for your ideas. I have a Shenniu SN254 which had a stuck clutch after sitting for over 6 months. I used your idea of pouring in 1 gallon of PB blaster. After letting it soak for a day, still no go. I hooked up the tractor to a tree and try to break the clutch in low range, first gear, still no go. When I finally decided to give up and drive the tractor to a spot where I take off the front end loader, it finally broke free. I drained the PB Blaster and looks like it's working fine. Thanks again, I dreaded having to break apart the tractor...
