Primary auto tensioner at 70k miles
#11
These forums always publish the bad things that happen. I thought I would share a bit of good news this time around.
Doing my 70 K mile service and decided to pull the outer primary to take a look at the auto tensioner. I have included pictures, the tensioner looks outstanding. it is not notched up very far in it's adjustment range. The shoe looks great without any excessive wear.

Though i like to browse these forums they are in no way an accurate real world data base when it comes to product reliability. The MOCO abuses every aspect of bike development to ensure reliability. Your experience imo is probably the norm when it comes to compensator wear. Looks like you have many many miles left on it.

Long story short, didn't make a lick of difference in pursuit of the noise. 4 dealerships later with no resolution, I said screw it, I'll keep riding till it gets worse or grenades. It's under warranty. About 3-4k later, it went away on its own and never came back, never presented any issues, never any metal in any of the fluid.
As for grooves in the shoes, if you look closely at the photos, the chain across the shoes are pretty much level all the way across. If there were heavy grooves, the chain would be set down into the grooves. As for the presence of "any" groove such as one at 0.005" deep, then yeah I wouldn't see it with the chain still in place. However, failures that I see from previous generations have the chain half way down into the shoe. 0.500" (half an inch deep, down to the chain side plate rivets)
So at 70k miles, I think it looks dandy!

On a roller type chain, once the links groove in, the rollers roll. It will never wear after that. Same for the cam chains once Harley went to the roller chain in there.
Mabe at 100K, if you were in there, should replace it since Delrin gets brittle in time from the constant hot oil bath.
