Hmmm, well that might be part of the redesign then. The screwdriver does not go in and out on the one I have. This one has what's left of a pink dot. What does that mean? Erm, nothing as far as I'm concerned. The spring was still inside the body. Anyone out there have an updated one they want to tear apart? Is the interior of the CCT body threaded? That would be the only way the internals would move in and out.

 

Well, I can tell you all this much. The part number changed in '03. I've attached a pic of the microfiche and part numbers. The pic in the fiche is the same as what I have. Dunno if they look any different externally.

 

Hi Jamie and Greg;
This is a very interesting discussion. Both of you have some insight, but having one to take apart and study makes Greg's comments carry some weight. I,m likely going to order some APE's, but I'll watch this for a bit. Our riding season is done so I have till April to sort this out. I tend to mile bikes pretty quickly... at least for the Canadian climate. I will not take a chance of fragging this sweet engine. I know these things get blown out of shape, but it obviously has been happening. Has there ever been any surverys of this..Like
Problem yes/no

Colour...........Kidding
Really appreciate you two applying your obvious skills to this issue

Take Care

Hmm... My new CCT's are obviously installed and I don't wan't to tear that apart to check... but looking at the old one's (I'm a packrat... I NEVER throw ANYTHING away...) these too stay stationary... and on the outside all looks the same...

From what I remember when having both parts in my hand and comparing, the black part was longer overall but the the end part the same length, sligthly different shaped, making the tapered part longer... the different shape could be wear on the old part... but I don't think so... the new part kinda had "knotches" ?! to fit against the base of the CCT guide (correct word?) where the old was smoother (and I imagine the wear would instead leave grooves, not smoothen it...)

What difference a longer tapared area has... beats me... migth make it less likely to move sideways?

 

Also Gregg is right... the only way anything can move when failing is inwards... which would be really catastrophic... Which makes changing bolts redundant... pity, it was a nice idea to have a failsafe...

 

I've been thinking about this more. If Honda would incorporate a ratcheting mechanism into the CCT this would prevent catastrophic engine failure in the event of CCT spring failure. It wouldn't be that difficult to do. Just machine the plunger with some teeth and incorporate a small spring and hinged lever to the locating plate. Guess that's too complicated for the "Cam Chain Tensioner Engineer" to figure out.

 

Which is a bit surprising... as they on almost all other occasions go to great lengths to ensure longeivety and reliability on their bikes...
