Redoing the top end on my 1995 RK. I have adjustable pushrods but cannot find what make they are or how much to adjust them ?
They have VERY fine adjustment threads & the only markings I find on them are GGG on the locknut.
Please help me out if you can ??!!
You need to preload the lifter .100". Figure out the number of thread per inch. Divide that number by 10 and that is the rotations of the pushrod. EX I have 40 threads per inch and should adjust to 4 full turns to move .100".
Set the rod with no movement and not compressing the lifter(with the lifters at the bottom of the cam lobe) Turn it out the required number and tighten. After adjustment you must wait till the rod can spin freely, that tells you the lifter has bled off and you have no chance to hit the piton while turning the motor over.
That said I usually turn mine another 1/2 turn or so and it seems to be a little quieter.
Probably more than you were asking for but....
If they're all black and the "G"'s are all around the diameter, they're screamin' eagle rods, they should collaple enough to remove them without taking of the rockers. I bent one of mine bolting a rocker box back on before I figured that one out...
I think they say 2.5 turns from finger tight, but you can double check by downloading the instuctions from HD's online store.
