be careful if you use the twisting the pushrod to determine zero clearance. My Crane Hydraulic rollers have very weak springs in them and it is extremely difficult to determine the zero clearance point.

I found it worked better to try and move the pushrod up and down, while holding it between your thumb and index finger. Found I could determine the zero lash point much more accurately.

The "rotate to determine" method works great if the spring in the lifter body is relatively stiff but in my case, it was very easy to make an error
