How to Install Harley M6 Auto Tensioner on Harley M8

[@henryjones4709]

When you first installed the shoe was backwards. The second and third time you face the shoe correctly. There’s a grove cut to fit over the front bolt hole when compressed. I did the same thing when I installed mine. Great video

Thanks, someone else mentioned that too. I didn’t realize it was directional, when I installed it, glad I got it right 👍

Hard to tell exactly where you are measuring from, but I believe the measurement is from top of shim to bottom of tensioner. That measurement/clearance allows tensioner to move up and down freely without bottoming out. Also a good rule of thumb is to fill primary to bottom of clutch diaphragm spring/pressure plate, with bike upright. Most All bikes that is 32oz/1Qt or 36-40oz. Regardless bottom of pressure plate.

It would have been nice to see you start it up

I have it on a KZbin short, minimal noise 👍

how's the chain tension before you remove the stock?

[@InfamousCreep]

It’s automatic tensioner but, per Harley manual it should be 5/8. Hayden manual wants it at 3/8, so I kept it at 1/2”

ooo! ooo! Do mine next!

13:06 if you aren't sure how much is in there, why not to a dry fill right off the bat?

You're measuring wrong for the 3/8" spacing, by adding the shims you're decreasing the space not increasing. The shims are for primary chains that have stretched out over time. Hayden support doesn't exist and they need to correct this issue.

🤔🤔, there’s no mention of that in the instructions. I also went ahead and added a bit more slack in the chain. I’m glad I did if what you mentioned is true 👍

[@InfamousCreep]

I know having a tight chain could damage the comp or clutch basket, so I kept it at 1/2” instead of 3/8”

[@BikesBeardsAndBrews]

a C hair away from 3/8ths?

This looks like more trouble than it's worth 😳
