HD Clutch Recall 2018...Over 200,000 Affected!

Here is a look inside the AIM slave cylinder

I see multiple seals on the piston I like this

I'm gonna have to swim against the tide on this one as I prefer the HD slave. The AIM claimed 40% reduction in lever pressure is probly due, at least in part, to the reduced surface drag of the o-rings as opposed to a square cut seal and maybe a lighter spring.

Maybe me being 'old school' but I like the tried 'n true design much better and just don't trust round cut o-rings in this application.

What was the story that went along with this picture? I see a chip on the parting surface.

I was curious what gave the AIM actuator 40% reduced pull, i.e. different spring
rate
& or a bigger piston (more surface area). There is a big difference in price with the HD part at $60 & the AIM at $280:xzqxz:

Interesting point. From an engineering standpoint, the elastomer square cut seals are generally used more in static sealing applications than dynamic ones. If the materials, compression and gland fill on the o-ring is right, it can provide the needed seal reliability. Quad rings would be an interesting test (assuming there is an opportunity to improve on the improvement :laugh:)

IMO an O ring type seal will stand up better than a conventional square cut seal

We are dealing with heat and constant pressure here to seal the fluid , A hostile work place if you will;)
 
I got the call this morning and went to the Harley dealer, took 1 1/2 hour and out the door.

Good to hear. I'm getting my 1st. shakedown ride tomorrow to test it out.

Did you notice any difference in the operation?
 
Just a quick update after the cluth recall was completed.

I got a 75 mile ride in today & could actually feel my fingers ( 60 & sunny).

The cluth operation is definately improved & if I had to put a number on it, I would say the pull is reduced 10-15%.

Also, easier to hold in at an extended stop. I'm happy.:cool:

Just got my trike back today from having the clutch recall done. Can't say I really noticed any difference. I didn't have any problems with the clutch before I brought it in. At least it's done.

If it was not for the recall I would not take mine in

I have bleed mine 2 times and am having no problems

I felt the same way, but after getting it done I thought that unit/seal could fail at any time. With age, the failure rate could increase dramatically.

In my opinion , I'm giving the MoCo props on this one in the way they handled this, speed wise.

I have waited 6 months for some auto safety recalls. Some wait years.

HD handles a lot wrong, but I think this problem was handled well. Thats as long as the fix holds up!:cool:
 
This past Saturday my dealer dropped off my neighbor's TriGlide that was in for the recall and my Sportster that was in for 5,000 mile service. He then loaded up my wife's FreeWheeler for the recall service.
 
Well, what do you think? Did you get enough of a ride in to form an opinion ?

The pull seems lighter, other than that no big change cept my trike is clean:p

My dealer always washes bikes in for service

When I got there there was 2 other trikes waiting for the same service

All 3 trikes went in @ the same time, All 3 came out @ the same time

Pretty good service IMO

Good to hear Jack. Yes, the washing after service is a nice touch the good dealers do. Doc's HD in St. Louis does that, I have not had service at my other local dealerships.
