Was in the middle of taking apart the touch control unit (TCU) for a rebuild on a SuperA when the grandsons wanted to stop by. Cleaned up the shop for them and that came back to bite me.
Turns out the there are 2 different thickness’s of the TCU head gasket. Depends on the tractor serial number. But I remember replacing the whole TCU about 25 years ago so no real way to know which gasket to use except to measure the old one . And, yeah that part got thrown out when I cleaned up! So I guess I now have a 50/50 chance of guessing which one is right - wish me luck!
