When you adjust the pushrods on any H-D Evolution or later engine, you must compress the tappet by 0.100". According to the list that I have, you must turn the pushrod three complete turns (18 flats) to lengthen it this much. I'd double check your pushrods to make sure this is correct. Find a point where you can measure the pushrod and take a measurement using a dial caliper. Turn the pushrod to extend it by three full turns and remeasure the pushrod. It should be 0.100" longer.

To install your pushrods, bring one piston to top dead center on the compression stroke. Make sure that both tappets on that cylinder are as low as they go in their bores. Install the pushrod with the pushrod tube into the head. Make sure you've got the O-rings in the head and the tappet block. Extend the pushrod by turning it with your fingers until it gets tight. Then, turn it three more turns using wrenches and lock the locknut. Do the same with the other pushrod. Let the engine sit and do not turn the engine until the tappets bleed down and you can again turn the pushrods with your fingers. This may take as long as ten minutes. Once you can turn the pushrods by hand. Bring the other cylinder to top dead center on the compression stroke. Make sure that both tappets are at the low point in their bore. Install the other two pushrods the same as you did the first two and allow the engine to set until the tappets bleed down. Once you can spin the pushrods in your fingers. Finish installing the pushrod tubes.

Now, this is accurate provided your pushrods have a 32 threads per inch adjuster. If not, you must figure out how many "flats" that you have to turn the pushrod to lengthen it by 0.100". Substitute this number of flats in for the number of turns to lengthen the pushrod after you get it finger tight.

The tappet plunger has approx. 0.200" of travel in it. You want to adjust the pushrod so that the plunger in the tappet is about mid way in it's travel or 0.100" or there abouts.

Good Luck
Steve

SOURCE: how do i adjust screaming eagle pushrods

I think the SE pushrods have a 32 TPI pitch on the threads. If so, with the tappet all the way down in it's bore, adjust the pushrod longer until it make contact with the tappet plunger. Now, continue to lengthen the pushrod by 18 flats or three turns. Allow the tappet to bleed down before you turn the engine over. When you can turn the pushrod with your fingers, you can safely turn the engine.

The object is to adjust the plunger in the hydraulic tappet to approximately the middle of it's travel. The tappest have about 0.200" of travel. So, you want to adjust the pushrod out until it has zero clearance then go another 0.100" inch. You can measure how much three turns lenghtens the pushrod before you install them just to make sure.

Good Luck

Harley torque specs


Factory Evo lifters have a range of adjustment/compensation of a little over .200 of an inch. Your aim is to set the pushrods to run in the middle of that range. Screamin Eagle pushrods use a 24-pitch thread, which lengthens them by .041 n change per turn. Set the pushrod in place with the lifterer all the way down, adjust to zero play, then extend it by 15 flats of the hex, to a total of 2-1/2 turns, extending the pushrod .100 of an inch. This puts it in the middle of travel of the lifter, and you're on to the next! Remember to allow plenty of time for the lifters to bleed off oil between each rod adjustment before turning the engine, to avoid bottoming out a valve. Adjust one at a time, 10 minutes wait time between each pushrod is a good rule of thumb. Ride safe!

2006 street glide flhx. noisey valve train .geting worse.only 20.000 miles .just started in the last 2000 miles. are push rod ajustable? how can you tell if cam teniture is bad?


The stock pushrods are not adjustable. Screamin' Eagle pushrods from Harley are adjustable. To check the cam tensioners, you have to remove the cam cover on the right side of the motor to see the tensioners. You will need a flashlight to see the tensioner on the back side of the cam plate. If the plastic on the tensioners show excesssive wear, replace them. They typically need replacement after about 30,000 miles, but I've replaced them at 20,000 to 60,000+. I just put new ones in my Fatboy at 32,000. Have you recently changed from conventional oil to synthetic? This can give you a bit more valvetrain noise, due to the thinnner synthetic oil.

Need first steps to adjusting push rods didnt mark the pushrods as we removed them the bike is 80 cubic inch electra glide 1994


Uhh, if the pushrods in your 1994 model bike were stock, they are not adjustable. They should be color coded at to where they go. If this is what you have, they go in the following positions:
Purple - Rear Exhaust
Blue - Rear Intake
Yellow - Front Intake
Green - Front exhaust

Now, if they have been changed to adjustable push rods by you or some previous owner, the first thing you have to do is figure out how many turns of the adjuster it takes to make the pushrod 0.100" longer. Turn the adjuster all the way inward making the pushrod as short as possible. Now, using a caliper, turn the adjuster outwards until you get a measurement of threaded rod that is exactly one hundred thousandts long. Then turn the adjust all the way back inward while counting the number of "flats" on the hex adjuster that you turn until it bottoms out. You must do it this way because different manufacturers of the pushrods use different thread pitches on their adjusters.

Once you know how many "flats" it takes to make the pushrods 0.100" longer install the pushrod into a position with the tappet all the way down. Adjust the pushrod out using your fingers until you get all the slack out of the pushrod. Then turn the pushrod adjuster outwards the number of turns that it takes to make the pushrod exactly 0.100" longer.

Once this is done, you will not be able to turn the pushrod. You must wait for the hydraulic tappet to bleed down before you can turn the engine. If you do turn the engine before the tappet bleeds down, you may bend the valve. Do not turn the engine until you can turn the pushrod with your fingers. Proceed until you get all pushrods installed and adjusted in this manner.

Ride Safe,
Steve

I have a ninty five cubic inch engine with screamin' eagle race heads,high compression pistons,411 cams with jims power glide 2 lifters,screamin' eagle cam plate,with high volume oil pump,adjustable...


Additional "sounds" or "noise" from modified motors are fairly "normal" when the engines are at full operating temperatures. Changing you brand or weight of engine oil might have a slight effect in sound reduction, but if everything else seems okay then I'd just ride and enjoy it and keep an "ear" on things.

Looking for instructions to adjust valves on 1987 H.D.


If the engine is stock, there is no adjustment to the valves. The engine is equipped with hydraulic tappets that take up for any wear or heat expansion of the cylinders. The pushrods are non-adjustable but are of different lengths. They are color-coded as to what position they go in.

Now, if your engine has been modified and adjustable pushrods installed, they should work the same way unless they are way out of adjustment. Then, it depends on "whose" pushrods they are as not all pushrods have the same threaded ends on them. But, all is not lost.

Take one of the pushrods out of the engine and adjust the pushrod as short as it will go. Now, turn the end out until it makes the pushrod exactly 0.100" longer while counting the "flats" on the adjuster. When you install the pushrod, make sure the tappet is at it's lowest point in the bore. Put the pushrod in, don't forget the tube and the new O-rings, and adjust the pushrod out until you have zero backlash. Then adjust it out the additional number of "flats" that it took to make it exactly 0.100" longer. Lock the adjuster down. What you're doing here is the plunger of the tappet has a travel of 0.200" total and you're adjusting the pushrod so that the plunger is halfway in the middle of its travel so that it's got equal travel in both the up and down direction.

Good Luck

Not unless you have/buy a Screaming Eagle or aftermarket ignition module. What makes you think the timing needs adjusted? It's all computer controlled.
