Re: control valves and cyllinder bore for digger
ok. Now take a flat tip screwdriver & push the valve plunger rod down so you can push the eccentric roller all the way on. The bearing'd roller is atop the valve rod. The valve rod is spring loaded from the bottom only.
When it comes time to start your hyd system for the 1st time, then you will reset center with each valve & then use the thumbscrew to hold it in place, you can't guess it before hand.
Use a large enough flat tip screwdriver within the machined cross of the eccentric roller, doesn't matter which way you turn, turn far enough to get the cyl to go the other way & then back up some. That'll be center on the valve & when you set the thumbscrew to hold the valve till your servo is installed.
