- How to install a Hayden primary chain tensioner. This is on my 2009 Harley Davidson Road King to replace the factory ratcheting primary chain tensioner, which had over 60,000 miles on it. I experienced kind of a whining sound coming from the new tensioner as the chain links settled into a groove in the new tensioner shoe for around 1,000 miles or so. Barely noticeable now.

Next on the agenda will be replacing the weak engine compensator. In later years Harley Davidson discontinued use of this type and instead installed the Screamin' Eagle version on the new-at-the-time 96 cubic inch motors.

Love your videos, detailed and informative. Keep it up!
Mikey Z I really liked hearing that, thank you!
Ran a Hayden on my evo for 60,000 miles. No problems and never needed any adjustments. I put down disposable diapers to catch spills.
i put one in a 72 sport had in 96 or 97 they been around a while,it worked great
Thanks for sharing that info! I'm still using mine, just with 3/16 gap instead of the recommended 3/8 gap, and only the larger spring as I left the skinny one out because with it in at the lesser gap it felt too tight.
Does anyone know if this fits the 2007 bigdog bulldog with a 117 cu in baker 6 speed?
Thanks in advance
Most people dont know that the stock auto tensioner has two springs. One gives some slack, the other moves the ratchet. So the ratchet is like those shims. Just check it occasionally to make sure nothing strange happened and it ramped up too tight.
I believe if you have less than 3/8ths its probably due to new chain or new bike. Shims are for stretched chains. I also think they should put in the update "no more than 3/8ths. My chain still clunks but its probably easier on the shafts than the stock ratchet style.
On a side note; I'm getting chain slap...
Many decades ago I had an HD with a belt primary. That was the hot setup, But now that seems to be gone. The belt was great why did it go away???
Good question, Joseph.
Personally I believe that belts at the time we're probably no longer considered reliable. Maybe the rubber they used was too soft or crumbled over time? Also there's the worry of getting rocks in it.....yeesh
to answer your ? did you install it or was it a factory belt. HD. used a belt in the sturgis dyna model. they stoped because you need to vent the primary well to rid it of heat, detrimental to belts. also the main crankshaft seal in the primary needs lubrication to last and keep oil in the engine. belts are run dry.
Thanks for the input....I also have one
Glad to hear it, and I don't anticipate any issues with it.

Hey thanks Mark,, keep the shiny side up and rubber side down.. Scott
Scott Liegel You're welcome, Scott, and same to you on the happy trails!
Bought one of these for my Twin Cam but, bike went before installing after a write off. Now. Will it fit the 114” M8 engine primary that I just bought?
That's a good question to which I do not have the answer. The automatic chain tensioners in the newer M8's seem to be further refined though.
My 2012 RoadKing has the same setup
After a year of running, do you still like the Hayden??
Big Rig Rich Jumper yes, it seems to be a quality product for the price. It will whine for the first 500 to 1000 miles, but it gradually goes away to the point where it's about the same sound as the stock unit. I do wonder if it interferes with starting the bike sometimes due to its spring bouncing up and down as the clutch pulls the chain to turn the motor over. I haven't seen anyone else mention that though, could be just me.
I have the stock adjustable chain tensioner and out on my 03,, can I just order a Hayden automatic tensioner and have it both right in?
Someone may correct me if I'm wrong here, but I do NOT believe the Hayden primary chain tensioner will bolt right into your 2003. The Hayden unit was mostly developed to replace the factory automatic rachet-style primary chain tensioner on newer motorcycles. Just make sure your chain play is set to factory specs and the condition of the plastic shoe from time to time, Scott, and you should be good to go!
I do believe hayden does make one for that year i know they do for a 2000 flhr
Thank you for your correction, Eric!
Hey Mark thanks for cutting in and I know this is an old thread.
I stayed away from automatic chain tensioners,, if you go over one heavy bump,, especially on a Softail,, you go over one have a bump and it will ratchet it right up,, nothing worse than a tight primary chain..
Even Baker,, the most expensive
But it's all up to preference,,
Stay loose 🤙
Thanks for letting me know, Scott! Safe and happy riding!
HEY DID YOU CHANGE THE COMPENSATOR AND DID THE NOICE CHANGE.
Yes, I upgraded to the Screamin Eagle compensator, which became standard OEM in 2011 or 2012. Had to change the stator rotor with the compensator to have the proper setup and chain alignment. Was it worth it? Yes.
Your pre install, chain tension looked to be with in spec.
I used that kit before sir an i hated it if you ride a little aggressive the chain will rattle
I wonder why Harley-Davidson is still using this in the new Milwaukee 8 motor. A gear drive primary is more modern and they could keep the traditional primary cover.
Probably tradition, Frank. I dunno. Lol
Just an observation, but it looks like the right mounting bolt blocks off flow back to the drainplug magnet. Is there clearance there? Thanks
Yes, there is a gap underneath the primary chain tensioner to allow fluid to move back and forth, or to be drained for the most part.
@@contact4mwy7 Thanks!
Well Mark after 2k miles I'm noticing a small ticking noise at idle sounds like the chain is slapping the outer cover I'm gonna take it apart again it already has 2 spacers
What was the gap measurement with the two spacers? I tried to make the chain touch the top of the inner primary with 3/8 gap and there wasn't enough slack in the chain to do that before the chain tensioner bottomed out. I uploaded a video called Another Source Of Primary Noise, which shows how the clutch basket can make a knocking sound, could that be it? Mine makes this clatter between shifts or at times between slowing down and maintaining speed.
@@contact4mwy7 3/8 of an inch is what I had with 2 shims bike has 50k mile so I'm sure the chain is stretched, I'll keep u posted on what I see and a new measument
@@nswiss19751 ok, thanks. I can't imagine it is able to slap on the top of the inner primary with that measurement as I tried to make that happen and the shoe bottomed out with at least a quarter inch gap between the top of the inner primary. Check the clutch basket jiggle while you're in there, and please keep me posted! Thanks!
Sounds like a stretched out chain
How does that Hayden chain tensioner know how to preset the tension,, on a cold engine there should be 5/8 to 7 / 8 engine,, hot 3-5" of play ?
The tension is pre-set by both the double springs underneath the shoe, and the gap between the shoe and the baseplate. Shims are provided if needed to shorten the gap to the recommended 3/8". I will be uploaded another video which explains it better and offers a bit of a modification for smoother starting and less pogo-stick decelerations.
I swapped my non adjustable 03' for 06' adjustable an Now I'm getting that awful clunking noice! Ready to put original back on but I see your video here! What's this brand an why buy an replace?
They want you to zip tie unit together so it does expand on removal!
Yes they do. Its under a bit of pressure to expand fully. Be careful.
By the way, the earlier chain tensioners had coarse teeth on the ramp compared to the newer units. You might be better off putting the non adjustable one back in and just keep an eye on it from time to time for correct tension.
@@contact4mwy7 Thanks, that is my plan now to put non adjustable back in ! I'm researching "Hayden" accessory
My adjustable tensioner was really tight while upper chain was tight too! I knew then I had to go back to original or better up grade! I about cr$ped my pants first time I heard the primary clunking sound! I don't want that happening again!
Harley-Davidson does not need to still be using a chain primary drive system at all. A gear drive primary is smoother and less maintenance and HD know it to and they will go to a gear drive sooner rather than later trust me. It’s a legacy item that outdated with the chain drive.
Frank Wood that would be quite a change in the setup alright. I wonder if it will happen?
like this one for chevy small blocks. www.summitracing.com/parts/pro-66917c?seid=srese1&cm_mmc=pla-google-_-shopping-_-srese1-_-proform-parts&gclid=Cj0KCQjw6rXeBRD3ARIsAD9ni9CFjVxq1tgzPijkJ65bvSFWTafks3zdHCG62kpenem1CDXgKos9G-saAlcKEALw_wcB
fix torque compensator immediately, do not ride for a year with it bangin back and forth
Planning on replacing it myself this Spring, Mark. Those compensators are junk! Video to follow... LOL
I understand why harley is called America's bike, because we, the people, gotta fix what harley engineers can't.! Where are they getting these clowns? And why don't they document their flaws? Must be day labor temp to hire idiots huh? Anyway good vid
jb sometimes I think we the customers are the "R&D Department! Haha

I have an aat in drafting and machine design and i would have,and I'll bet many will agree, made most parts interchangeable. I bought a 2010 flstc engine and a 2005 fxd tranny. Hahaha. I gotta make my own primary and custom lenght chain. Of course, my dumbass didnt know what i was getting into. I assumed. I'll let ya know how that works out. I bought a carb too but ill need a efi unit. Damn
jb whooaa, man, that would be a great video to see! You're right, there are many different parts depending on the model and year. I added an extra spring washer as a sort of "shim" against the original four rings for now and it has been working fine so far, but will be swapping that compensator out for a Screamin Eagle unit at some point.
didnt show how to remove the harley tensioner... fail
If you can't figure that out yourself, maybe you shouldn't be wrenching on your own...
@@lafincow12 I figured it out on my own.. but If I were posting a how to video, I would include the details... they are nice to see
