    After I've heard from a Harley Builder ,that was a retired engineer from Chevy.
    And another build talk about when he build motors.
    He always puts the Hayden tensioner in.
    Why haven't you ever used them.

    Watch the video or look at the instructions.

    Tell me what you find about it.

    It has a Plate, 2 springs, a outter and inner and a Shoe and it held on with the 2 bolts.

    How else can you set it up.

    In theory. I suppose you will start with the smallest shim till you vet the proper slack in the chain .taking a reading at the diffrent spots as you rotate the motor. Find the best fit .if its still to tight you would have to remove some material from the bottom of the shoe if its to tight with the smallest shim.

    But is putting the shims in not gonna make it tighter ?

    With no shims in I had less than 3/8 of an inch in the measurement.

    How much slack does the HD one give you?

    Didn't measure it. It had some slack at the top oh.
    They had it completely loose. And the mechanic said as I ride it , it would adjust as it needs it.
    He just showed me that at 31,000 miles it has very little scaring on the stock shoe.
    He is also the mechanic that put a 120R motor in a Rocker and had to beef up everything.
    Don't know if stated that or not.

    Shims are the only way I guess, they have redesigned it, frankly I don't hear of many folks changing the HD tensioner out since they went to the self adjusting, that was the point of the Hayden and other auto tensioner units that were all the rage in the early 00's You used to have to adjust the primary chain now you don't even have an inspection port with the new tensioner it's just not that big a deal.

    The power you're putting out shouldn't be a problem for the stock one...

    if the measurment was less than spec. then the tensioner would most likely put to much pressure on the shoe. (not trying to stick up for Hayden) the side links would wear into the shoe first causing the pattern in pic, BUT the material looks p/o from to much friction. to tight of a chain between to shafts puts a lot of stress on everything. good to hear all is well with your build. ride it like you

    And if the measurement was greater than 3/8 of an inch you would have to use shims to bring the tolerances down.

    cb, looking at step 4 on there web site instructions looks to me like the older or more stretched the chain more shims might be required or a new chain. if the measurment is less than there recomended 3/8 in. might that not put to much tension on chain?

    It didn't state that.
    If you watch the video. It shows the chain Bouncing up and down.
    Thought that might give it the slack it needed.
    All I know is a couple builder always sticks em in when they do a build.



    I got another friend that used to build Harley motors.
    He said they couldn't pay him to put it in.
    So I know they have ran them in older bikes.
    But I ain't putting it back in mine.

    And like I said you would have to remove material from the bottom of the shoe to decrease the tension. is the only way I can see. I think they hope the chain wears in the groove. And the slack gets created.

    The bottom of the shoe has a circle cut out for the spring to go into.
    It has a large spring and a smaller spring that fits into the larger spring.

    If you click on this link and look to the left it will show you the parts, and the bottom side of the shoe.

    Correct so to remove some in the circle area the spring sits in and in the sadle area of the shoe to decrease the amount of tension. It dont matter now any how .lol the one you got is better.!

    post #296 -300- 308 -315 .I have made choices in my efforts to improve my ride. I will try to always read instructions and follow. The manufactures of all products usually have tried to give us a good product if there is a (gray area/ ? ) call them and get an answer before things go poorly. hate me love me just an opinon on real life, dealing with public.

    Not what Tony Hayden with Hayden tensioners said.
    Talked to him on the phone myself.
