Take a look on pages 32 and 33 here http://harnerfarm.net/Jinma/Files/JINMA20-30A.pdf
Also here are a couple of scans from my parts manual

I think I would disconnect the drive shaft, that will separate the trans from the front end , no sense opening the wrong thing, also people have had issues with the drive shaft ends( they are not u-joints) , yes their balls fell out. some people redesigned the joint using what I do not remember to provide better engagement so it would not be a ongoing problem. I believe the joint is the weak point vs. they gearing ,but anything can break. let us know what you find.

Thanks for all the input. I did get the drive shaft apart over the weekend. The ball bearings did fall out on the spring side of the shaft. I put it all back together and it worked for about an hour. I am not sure, but I feel that the spring, that that holds the star washer and ultimately the balls in place, doesn’t have enough pressure to hold the star washer in place. Do I have the right assumption other than bad design?

I know I would not have made it like that,, but I have two Chinese tractors each with about 1000 hrs. on them and I have not had those issues with the drive. All I can say is to look at it and make a judgement on what can be done to make it better , so let me ask this was that your binding issue, I assume it was. And try to remember not to run in 4 wheel drive on pavement, I think it makes it a design problem worse . later on
