I have just over 500 miles on the "new" HD compensator with the oil splasher piece that glues in the primary cover. I also installed a Baker chain adjuster while I was in there. The bike had 28K on it (the factory Comp and chain adjuster were wore down).
I pulled the cover off the primary to make sure I had adjusted the tensioner correctly and that's when I noticed all the metal in the oil. I didn't see anything obvious at first so I pulled out the new compensator and found it was wearing the metal off the outside of the alternator rotor cover.

Has anyone else seen this?

 

So Im looking at the installation instruction sheet from my SE Compensator kit part #422000064A,42200095A Rev 2014-02-05 and comparing it to the Rev 2013-07-05 sheet and there is one major difference. The earlier version shows 2 SHIMS that fit between the spring pack assembly and the alternator rotor cover/assembly. The newest version which is the one I have does not show the shims. this is exactly where the wear is coming from. The spring pack is pressed directly against the alternator rotor and grinding away the softer metal and contaminating the oil.
I called the Harley helpline today to see if they could explain the change in design and their response was....... take it to the dealer. WFT????

Here is the link to the older version that shows the shims (#14 on page 4)

I'm thinking I need to add the shims to keep the wear to a minimum. ANY thoughts O wise ones?

 

I installed a SE compensator a month or so ago. There weren't any shims in my kit. (just the 5 spring washers) Chain was aligned and I don't have any noise or issues.

 

You didn' mention what year motor you have, Or if it is an 07-10 you need the new rotor to go with that compensator.

 

It appears he has an 11 RG, so stock was 30041-08 rotor (the pic also shows that there is no integrated spring pack.)

The current revision for that bike is 42200064A. From what I have read, they did away with the shims when they went from 42200064 to 42200064A.

The newer instructions ( -J05885.pdf ) removed the reference to those shims in step 10, but left it at step 17 ( which points to a different part then the shims anyway. Oops! )

I believe Baker has been trying to figure out what the hell HD is doing with those shims, tolerances, and alignment for a while now.

I don't understand how that should be wearing like that though. Where is the movement between the mating parts coming from?

 

With the springs riding right on the rotor I don't see haw this can be avoided. As for chain alignment i think they through the specs out the window.

 

You need the updated rotor 30041-08a with the new comp. The area where the spring washer seats is larger than the shaft extenion. Also more spring preasure.

 

It's a 2011 96" and the rotor is correct. It is the stock part which was upgraded after 2010. I went to the dealer and they also told me the rotor was correct. The tech told me he has no idea what could be causing the wear and has not seen that before. I didn't bring the parts with me but I had pics on my phone.


Apparently they eliminated the shims and made up for the space by adding material to the backside of the sliding cam. There should be a grove around the base on the newest revision but I can't check that until I get back home.
My first thought was maybe I didn't tighten the T70 bolt quite hard enough but I installed it to spec with a torque wrench and it was damn tough to get it off. It definitely was not loose.

 

I thought the shims may have been there as a barrier between the softer metal of the rotor cover and the hardened spring pack, but that was not the case. I would make no sense to eliminate them if they were.

 

The 08a rotor starts in 2014, 08 rotor 2011-14.
