I have the pedestal mount fms roller rockers and i am bolting them to a gt 40 head that has been milled but only one will not get tight the pushrod is a little loose. Do i need shims for all of them or just that one and what is the part #. Thanks
How loose is loose. Can you turn it very freely or is it just a little free? I know that when my friend and i adjusted the roller rockers some of the rods were a easly to turn.
some need shims some dont you have to decide im shure some one will come along and tell you some pns but you might need to shim 3 and none of the others and then again none might have t be
Think about what you're saying - shimming it raises the rocker - that will make the gap between pushrod and rocker even greater! You don't need to shim it if the pushrod is already too short to close the gap. You need to LOWER the rocker down onto the pushrod or get a longer pushrod. You might try removing material from the bottom of the pushrod fulcrum until you get the rocker low enough to close the gap AND preload the lifter. Be careful....
