Trial and error is your best calculation.

Did you note the spring plate angle before you took everything apart? Start one or two clicks higher and keep track. By some miricle I got mine right on the first attempt.

You can use blocks of wood under the bananas to approximate wheel height so you don't have to fight that. Calculators are nice, but dont account for stiction and component wear.

Slap 'em in and go. May take once, twice, maybe even three times.
