lifter preload setting>>

I know that Crane recommends .060" of preload. And as said in post #4 you really should find out what the thread pitch is in the rocker arm.
So lets say it has a 16 thread per inch thread. Then one full turn would give you .062" of travel.
Then sometimes you just have to do it the way TrailBeast says, while it's running. Messy but effective.
