touch control overhaul in process - extra small spring ?

I'm going back together will the 100 touch control unit, and have an extra spring. Is it possible it came from behind the # 20 safety valve piston?

I have (4) small springs & nylon guides for the 4 check valves, so it's not one of them, though it is about the same size

I wasn'table to remove #26 pressure regulator valve seat, and behind it, the ball check valve is still spring loaded.

It is smaller than #18 safety valve spring.

i think it came out of the safety valve hole, it is small enough to fit inside # 20 safety valve piston.

ALSO does the closed end of #20 Safety Valve Piston face the rear of the tractor ? This would mean the open end pushes against the ball, and this small spring can fit inside the open end of the safety valve piston and push against the ball instead of the open end of the piston.

Any ideas ?

Couv, I don't see another spring in my manuals, but I DO see what is either a nub or the tip of a tiny spring on the rear of that piston in the manual picture. I just could not remember if I had a tiny spring inside the safety piston, so I took the picture I had of the innards of my touch-control and 'blew' it up to look at that #20 safety piston...



...but I STILL can't see if that's a spring peeking out, or a solid nub on the rearward end of the piston (rearward being 'down' in the pic and rearward on the tractor). You also said "it is small enough to fit inside # 20 safety valve piston". So I would say that if your safety piston does NOT have a nub, and your mystery spring fits in there, then you have a match.
I did NOT have a spring that came out from that bore AFTER the piston came out, nor do I see one in the manuals.

BTW, when I placed my pieces on the table, I kept them properly oriented as to how they came out, so orient your piston as it is in the picture when you put it back in.

You're throwing a curve ball when you say 'the #20 safety piston pushes against a ball". The only ball I remember is in the next bore under.

BTW, if you want to remove the #26 Pressure Regulator Valve Seat, get one of these sockets like in the picture. I forget it's particular name, but I got it at NAPA.



Hope all this was clear! If not, or you need any other pictures, ask again.

I remember. It"s called a "drag link" socket.
