Thanks for the insight. The goodness of putting it on first is that it gets the geometry of the raised part of the piston, which has to face one way, to be correct. The FSM makes a big deal about that.
I tried boot installation both ways relative to having the heat shield on. Ultimately I did leave it on for orientation.
The boot was best installed hanging off the front like this:
The challenge is that when seated nicely on one side:
The other side is way off and falls in the bore.
So you need to get the boot hanging off with minimal slack in the overhang part, so just enough is there, then hold the seal in place in some amount of the circumference, and move the piston (it’s not pressed in yet) to generate the stack.
