Frank, Harley adjustable pushrod installation needs to follow the explicit instructions on how to adjust properly. If you know what your pushrods are, we suggest going on the internet and reading the manufacturers instructions. Usually when you adjust pushrods with hydraulic lifters you start by removing your spark plugs. Put the m/c in 5th or 6th gear. Turn your motor, by hand, and position the lifter you are adjusting to its lowest point of travel on the cam. Next, extend your adjustable pushrod until you have zero lash (adjust by hand until you pushrod is seated, but without collapsing the lifter). Next, (depending on the manufacturers instructions) you may be instructed to extend the pushrod another 2 1/2 to, maybe, 3 full turns. Now, you will have to wait for the lifter to bleed down. This will usually take at least 10 minutes per lifter when you are using lifters that have been in service. Do not try to turn motor until you can physically spin your adjusted pushrod with your fingers. If you do not wait for the lifter to bleed down, you risk bending a valve. We demonstrate how to adjust pushrods on our Andrews Cam Install Video. Check it out if you can. A visual may be helpful.
