I've got my primary cover off and noted that I've got about 0.080" wear (grooves) in the delrin wear bar block.

How much wear is too much wear?

Approx 22,800 miles on this S2.

TIA...Steve

If its the original shoe, then replace it. It's been superseded by a new one that's far less susceptible to breaking apart. Consider yourself lucky.

I just went down to Hal's and ordered it.

From the google BadWeb search I did, most posts say that if grooves are worn into the shoe, then the primary chain was probably too tight.

Two_seasons notes: From the google BadWeb search I did, most posts say that if grooves are worn into the shoe, then the primary chain was probably too tight.

I don't buy that. The primary chain is steel and the shoe is a soft plastic bearing material (Delrin.) The bearing material has to have grooves worn in if it's doing its job, ie maintaining the proper tension on the primary chain.

I used to think that the primary chain stretched during use but now I'm convinced that the adjustment need on a new bike (new shoe) is only the shoe wearing in. I replaced the shoe on my 99 Sportster at about 85K miles. It was grooved but still working fine, ie the primary chain tension was maintained. I only replaced it to get the heavier based shoe.

That's my story and I'm sticking to it!

still working on mine trying to find that sweet spot where it doesn't whirr or rattle. When I'm throttle on the tension is on the top and the chain is coasting by the delrin. When I let off the throttle with the clutch still engaged the the bike's inertia is turning the engine and putting tension on the lower half of the chain and wearing the delrin, right?? Just thoughts

I always thought that shoe was made of nylon.
(not that it really matters of course!)

I agree, it's not rocket science. If in doubt ping Buellistic for the "101". : )

Be sure to find the tight spot. If the bike has ever been allowed to sit in humid conditions, the upper part of the chain (not immersed in oil) may have rusted while the rest of the chain did not.

I agree with Barry. The adjuster is GOING to have grooves in it. It makes no sense that it would not.

I got the new one. Apparently HD doesn't supply the nut with the shoe...

My grooves ARE NOT equal in depth. I should have been clear on that detail.

Man, it is storming out here. HD Big Bash, the 110 anniversary, is seeing hail, heavy rain, thunder. Perfect for a "bad weather biker" to be out in! But for now

Heck, the ones from Drag Specialties are made in Taiwan and have the nylock nut under the shoe screwed down solid so you have to bang off the shoe to loosen it up enough so you can install the part.
I think I'd insist on the genuine article.
Idiots!

It is not a nylock nut , it is a nylon washer bonded to the nut to seal it against the gearcase ; ) so it goes on the oposite way to a nylock nut would.

Underneath the SHOE (which goes inside of the cover) is a nylock nut. I spent enough time cursing at the stupid thing.

That looks like the one I got from Hal's.

Maybe the uneven grooves were caused by the nylok nut outside of the primary having some debris under the mating surface with the primary cover.

You should never have to remove that nut Steve, it is integral to the part.

At the time I wasn't very amused but I'm sure that the person who assembled the part is convinced that they're doing a splendid job by making sure that nut is just as tight as tight can be!
And then it passes the Quality Control Department...
