....On another note.........if you have extended warranty, it will not cover "worn out" cam chain tensioner shoes.....it will only cover the job if they're "broken".  I guess the moral of this story is to make sure that it's broke. [smiley=nixweiss.gif]

Even better then making sure they are broke versus worn out is to go with gear drive cams and eliminate this potential problem.

Thought I might add a couple more things to this thread.......

While in Sturgis (and in Cheyenne, Wy. on the way to Sturgis) I noticed that my bike was making more noise.

       The MoCo just completed a major redesign of the twin-cam platform with the 07 models. I am not saying any of you are wrong, but I cannot help but wonder why they did not go to gear drive. They have shown a propensity over the years for following the after market when it had a better mousetrap. Case in point , the primary chain tensioner released by the MoCo last year as an after sales item and now standard on 07 models. They also drop ideas that don't work out as the enclosed belt drive in the Sturgis models. Belt drives work when allowed to be open to the air and disipate heat, but not in a enclosed environment. Soooo I am wondering what in the gear driven cam setup they see they don't like. Logic would dictates that it would be way cheaper to produce, simpler to install and repair. So what are the drawbacks. Seems to me I recall that Hubbard retained his stock tensioners on advice from Tilly's ( or am I wrong here)

[highlight]From what I understand and have been told it's a simple noise issue[/highlight]. Because of all the other engine noise the motor makes w/o gear drive cams to go to gear drive would put it over the limit and it wouldn't pass the EPA noise limitation/restrictions.

I know there is a little bit more (different sound) that can be heard from them over my Rineharts. I would imagine w/a stock bike that this noise would even be greater and thus would create the problems passing the EPA tests.

Exactly what I was told by an HD Rep.  Additionally, it works out well for the MoCo as the savings to them is considerable going with the plastic tensioners in lieu of the costly gear drive.  Makes you wonder if it really is an EPA matter.

Exactly.  If my chitty tensioners can hold on for another three weeks [smiley=nervous.gif], I'll be in the clear.  Then the tensioners and the oil pump that all the plastic chit went through will be history. [smiley=huepfenjump3.gif]

I'm thinkin' if all they did was replace the shoes on JC's bike, they did a half-a$$ed job.  What about the shoes would cause the bike to lose oil pressure? [smiley=nixweiss.gif]

Here's a question on cam chain tensioners.

[grc]

Does S&S have a patent on the gear drive system?

 [smiley=nixweiss.gif]

Chip,

Yes, S&S has a patent on the gear drive.  The following is from their catalog:

MEETING THE NEEDS OF HIGH PERFORMANCE ENGINES The [highlight]patented S&S Gear Drive Cams [/highlight]are a must in order to achieve  the  full  potential  from  high  performance  Twin Cam  88  or  twin  cam  style  S&S  engines.    Since  the  chain drive  system  used  in  stock  Twin  Cam  88  engines,  is  not adequate to accurately control valve action at high rpm when  using  high  lift  cams  and  high  performance  valve springs,  a  different  system  was  needed.    The  S&S Gear Drive System was developed to improve performance and to eliminate potential engine damage caused by failure of the chain and tensioner system.

As much hassle as the MOCO gives S&S I would think it would be very awkward for the MOCO to use the gear drive system!

That would be interesting for S&S to sue Harley for copying their ideas.

I guess turnabout is fair play - I understand H-D sued S&S about using the Twin Cam name, among other things.

[hd-dude]

Exactly.

[110tHunDer]

Jim, that's exactly the point I was trying to make.  NOTHING about the shoes themselves will cause the oil pressure to drop, the pump has to be damaged (in this case from the shoe material).  So, if the dealer only replaced the shoes on JC's bike his oil pump probably looks like the one in your photographs. [smiley=nervous.gif]

[hd-dude]

I believe that they did replace the pump as well....JC, Can you confirm?
