What is the procedure for setting preload on hydraulic roller rockers? Some instructions say tighten the polylock to 20ft. lbs. after the pushrod has some resistance. I cannot reach 20ft. lbs. However if I just tighten 1/2 turn the plunger preloads the lifter about .040". Is this acceptable and the 20ft. lbs. refers to locking the polylock and set screw to each other? Pushrod length is perfectly centered on the valve.
