- Here Chris Waddell and Seth Haines demonstrate the vast difference between the TP roller rocker arms and the stock Harley rockers. Also, while Seth was attempting to demonstrate how to pump up a lifter for installation, we inadvertently revealed how little care Harley takes in prepping their lifters for installation. See the difference from the stock lifters to the Feuling HP+ Hydraulic lifters.

I just bought a 7201/525cam kit--this lifter/push rod discussion was perfect -thank you.
Put a piece of shrink wrap around the end or nozzle of the oil gun to create an seal to the lifter oil hole so it pumps up much faster
Graphic difference between the Fueling lifter and the factory lifter. Very interesting
Great information, shaky video. I own a 2019 street glide special 114 and videos like this have helped me determine what to do when I upgrade the performance of my bike. Thanks
I just removed the lifter's and put them back in after the change of inner bearing and cam shoes.. all good so far 😅
Here in Brazil we use to say… just take your lifters, light a candle beside it, put your knees to the ground, make a prayer and everything is goinnna be alright! 😅 It’s working for us so far.
All you have to do is put the lifter in a can of oil, put the push rod into the lifter socket and push it up and down and the lifter pumps up; done it with car engine lifters over the years, always works.
didn't work for mine not sure what's up with it
Whats the difference between fueling and s&s lifters?
Old video I know but I would pump the lifter over a small, clean container to catch the new oil so it can be put back into the can. Why waste good oil?
Hi so the lifters that you just took out of this 124 motor,, are those the same stock lifters they use in the Twin Cam 88 Motors, & so on? I guess my question is are all stock Harley-Davidson lifters the same ones they use in all Motors, I'm going to be replacing my hydro tensioner shoes with the Screamin Eagle upgrade kit, and I was told I also need to replace the tappets,, and they just recommended the stock Harley tappets so I'm wondering if all Harley tappets are the same,, thank you so much for explaining directionality of the lifters.. great vid. Scott y
Scotty Liegel yes they are all the same. If you don't believe me try to go ask your parts guy the part number and be amazed
Can you please explain why the tappets need to be "pumped up" with oil, but during the adjustment of the push rods, you have to let the tappets bleed down. Isn't that just letting the oil seep out that you just pumped in? I am trying to make some sense of that in my mind. Thx.
A tip from an old drag racer...
On a street engine we don't use "short travel" lifters... Of coarse we use short travel lifters in a Race Bike... Because we are reving 7,000 rpm.
And if you miss a gear rpm. Engine rpm. Will go way past the rpm. Limit... In that case, the lifters could pump up and bring your valves to hit each other... It's a Hemi, remember...
That's why they make a short travel lifter... On the street engine this is unnessasary...
And it will give you the ability to snug up on them, if you're chasing a noise...

That’s not why the engine chatters. It chatters because of the bolt that goes through rocker, it has play
On my ss quicky kit it states 2.5 rotations preload.(.unf thread )
What oil are you using to prime the tappets? My 2013 FLHX is at 50k miles and I plan to replace cams, tappets, bearings and tensioners this winter. Looking at S&S .550EZ start. Any tips or tricks you care to share?
Shovel sat for many years I bled the oil pump and did the same as these guys than your ready to go
Help I have S&S tappets with 6000 miles on the build I broke a wrench while adjusting the pushrods so some of the wrench pieces fell into the opening of the tappet ports so I was forced to take the tappets out I forgot to mark the tappets does it even matter can I just put the pushrods back in any order
Awesome! Many thanks for sharing.
Can i use stock push rods with the fueling racing lifters ?
Why do people do things there own way? The service Manuel says to put the lifter in the bore with the oil feed hole inboard. It dose matter or the Manuel wouldn't say specific.
5:45 the fill hole is actually facing inside, cuz more oil pumping
Just curious how does a roller rocker do such a phenomenal job? All the roller does is perhaps create less friction. That's it.but truly another thing to break.
Roller Rockers are only necessary when you have a high lift cam, otherwise its just a waste of Money
U answered your own question
@@RobertW15 ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,so many a-holes in this little world........................................................sickening
Cool, thanks...very informative.
you said 3 and half turns the Instructions say 4 turns??? for the pushrods
How difficult should it be to push down the center of a lifter that has oil in it ?
I jave brand new lifters for my 1998 evo. I oumped them up with oil as you guys have in the video. While holding a lifter in one hand, with my other hand, i can push the center of the lifter down with the push rod. It doesnt take much pressure. Definitely way less pressure than a valve spring.. this doesnt seem right to me. Should I be able to do this ? Shouldnt it basically feel like im pressing against something solid ?
if your engine is running at 45 pounds of oil pressure you would not be able to do that. but with no pressure on the lifter, yea easy peasy to push it down.
Do i need adjustable push rods if i'm changing over to roller rockers?
Do I need adjustable pushrods for these performance rockerarms?
Depending on the cam but most generally yes. We always use them
Factory suggest using adjustable
they don't tell you about measuring the lifter bore to the lifter. please read your manual for this procedure. also the pin that holds the lifter in place. there more to it. than what they are telling you.
Very informative, thank you. Just a little note, chocolate is not good for dogs.
Harleys are so awesome you buy the machine, install a different motor, take new motor for new and improved dangley bits.
engine* motor is electric
I've got new s&s Quickie push rods, and Fueling 4000 lifters to install very soon.
How many turns from zero lash would I need to go? 3 and half OR 4 ??
From zero lash 3.5 turns
So could you not just charge the lifter from the top?
Its very useful video
Would using assembly grease or red valvoline from a grease gun be alright to pump up lifters?
Use solid pushrods on high hp/tq builds is my path.
And solid lifters as well.
Can I used those roller rockers on a 95 ultra classic
When on your website and I could not find your rolling rockers that you’re showing in the video
You can give us a call at 765-768-6000 ext 1 if you need anything. We recently redesigned our website and allot of things are not on it yet.
Iv'e got 42k on my road king. Not had a single issue and I run it like it is indestructible.Guess I won't change.
,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,when ya get near 60k,,,,,shit happens,,,,,keep ya oil clean,,,,,and run full synthetic........
Fueling or s&s lifters for a stock 103 w/woods 222 cams
I just installed this exact set up in my street glide. S&S lifters , woods-222
Hay guys, I just installed Fueling cam plate chain drive pump lifters ,TP rockers. Crain htc 300-2 cams, S&S quick push rods, adjusted 3.3 turns re adjusted 3.5, 3.75, 4, and back to 3 turns. nothing makes much difference it is vary noisy. the only thing I did not as you do is bleed my lifters the way you do I soaked them for a few days in oil. and thought that would work we have done it that way always for our cars with no problems. I'm wondering if this could possibly be what is causing the top end rattle. I would think they would bleed out themselves by now. (this 300-2 is only 505 lift is it possible its just a bad combo?)
did you ever figure it out? having some of the same issues
To sharp of cam profile is what I have decided is the problem. I have roller rockers and the guys tell me that they are always going to rattle some. I did buy and install a set of woods lifters it did help but it was a lot of money and not a cure, I would not do it again. If you do try them mine worked best at 4 turns.
I'm running a .625 lift s&s cam so I'm guessing it's my problem as well.. so 4 turns works best then? I'm running crane cams roller rockers and I will give that 4 turns a try because 2nd 1/4 don't seem good and 3and 1/4 seemed a lot better so 4 it is lol thanks for the reply
you can try it and it may help but I tried 4 turns with stock and fueling hp lifters and it did not help. the only reason I did 4 turns on the woods lifters was because woods instructions say to.
OK thanks for the information and reply any help is surly appreciated for sure!
This video is not for those of us who work on our motorcycles this videos for those who don't and they make them think that this roller rockers gonna solve all noise and they could make some money for doing it for those who don't know how to walk work on their bikes simple as that talk about money
Just bought some new harley lifters from a dealer. My original lifters that came out of my bike , the oil hole is opposite the flats on the lifter. The new ones the oil hole is on the same side of the flats , just like the ones they are showing in this video. That changes the hole 180 degrees. So , instead of the oil hole facing either toward the moter , or away from the motor, it is going to face either forward to the front of the bike, or to the back. Does anyone know the correct direction? This is also going to have the oil galley come into play. The oil hole will be setting on the oil galley if turned in its direction. Will this impede the lifter from being pumped up?
Look at the lifter hes holding, it is going to have to face forward , or bacwards. Any advice out there.
PS. the lifters at the end of the vidoe are like my original lifters, oil hole opposite the flat.
It really does not matter
He stated the direction of the flat is all that matters!

Your commenting on a two year old post.
Just look at a small block Chevy with standard lifters can be installed in any position, the camshaft rotation causes the lifters to rotate when the engine runs, the movement of the lifter in the lifter bore along with oil pressure from the oil gallery in the engine block, supplied by oil pump, that is the basic operation of the hydraulic lifter.
You've got the rocker boxes open not use factory push rods? Better than adjustable.
Where are your rockers ,I don’t see them on website!

Since Harley uses China for a lot of products, who says the screaming eagle parts aren’t China made too??
I can't believe a 120R motor from the factory has not got roller rockers or HP lifters .that is disgraceful Harley Davidson ,shame on you .
Which is ironic because if they stopped coming up with whatever poo they throw at their fancy computers and payed attention to us. The ones doing rad shit. They’d make SO much more Money. Granted they do the “baddest bike on the showroom. But there is so much that could be done and they’d kill. Rather than flounder as they currently die.
My 120 r broke valve spring an bent two valve's just cruising down 17 Arizona , replaced all springs,lifters,valve's , an reported heads all upgrade from original crap , Harley cheapy commy parts !
Rocker lockers fix that
I'm confussed...ear ring left ear gay?
Good rule of thumb - left is right, right is wrong.
@jimkoch1040 I always said I'm left handed because I'm in my right mind 😅
No chocolate for the dog.
That valve tip is trash !
I saw that too.
lifter port on the out side is below port on the inside, `inside piston has a port just aboive port on the out side the piston on the inside with the valving is pused down and oil under pressure gos into the center piston and thru the one way valve at the bottom of inside piston . so when you pushin g oil thru the outside inlet port you just pushing oil thru the tight clearance because that port on the out side will be practilyshut closed untill you push the inside piston down just a little thats why when doing priming lifters you sumerge them then pump them from the top. .put oil in a 1 inch pvc pipe cap it bottom and pump the piston and you dont have oil all over the place youll see the bubbles come out the top. yea and auto lifters are not the same specs as harley lifters .auto lifters run high pressure HD run on lower psi
