I figured it out. I used logic. The shim kit is used between the gearbox and pump for the purpose of the spider gear.
The internet is suppose to save time by connecting across the world to find what a guy is looking for fast. Sofar finding internal pump and motor parts has taken over a month . I miss the yellow pages physical book, it didn't send me on wild goose chases.
The men that made this machine have my respect. It is simple and powerful and because of that I have been able to repair it myself. I'm a poor grumpy old farmer wanting to get things done.
I appreciate this site. I hope this helps others. I have service shop books not for sale but I can send pictures of what you need. All in the name of good will to men.
