What should I do with my CCT's ?
 

What would you do if you were me ?
VTR Model 2001, 28 000 kms (17 000 miles), no strange sound, stock honda CCT's pink dot.

Be careful of strange noises, check them, change them by new honda ones (orange dot ?), APE CCT's , OE CCT's ?

:roll:

Re: What should I do with my CCT's ?
 

Replace them with new stock ones if they are the updated models. I'm not sure if thats pink or white, etc.

If you already have the updated models, which I doubt, then if it were me, I'd replace them with the manual kind, not the APE but the other type that someone found that looks better built.

They're very easy to re and re. Personally I have more confidence in the manual CCT's

If it ain't broke...

don't fix it.

Re: What should I do with my CCT's ?
 

..or wait for it to break, which they are prone to do, and possibly be stuck on the side of the road with a hooped engine.

Re: What should I do with my CCT's ?
 

just my 2 cents about pink dot CCts etc.

As seems that I am guilty of mentioning orange dots here.
I know for sure that latest CCTs partnumber ends with -013. This is what I have now, purchased them in February this year.
My CCTs seem to have orange dots, but I might be as well color blind or Honda Germany (they stock parts for Belgium dealers) might've run out of pink paint. I am serious - may be they just look orange to me.
I would recommend to refer to part number rather than to color of dots.

Manual CCTs of better quality that I've found occasionally made by "Orient Express", sold by "BigCCracing" comany in UK and by list price cost about same with APEs.

All below is IMHO.

I think that all CCT thing grew in literally paranoia that already started to make people sell their Shawks or avoid buying one.
Chances for latest CCT to break are not any higher than chances to be hit by drunk driver or ride into idiot making u-turn in a middle of interstate (happened to one my colleague recently), so - riding a bike is a bit of a gamble anyway...shall we stop riding then?

Re: What should I do with my CCT's ?
 

This is a highly unlikely scenario. It's a tensioner. It gives plenty of warning when its going.

Re: What should I do with my CCT's ?
 

It happened to me. No warning 4 valves gone!

I think you had a different sort of failure.

Re: What should I do with my CCT's ?
 

There shoud've been some warning you missed - it is easy to miss.
I have played with CCTs for a while, trying Kawasaki CCTs, checking springs on old and new CCTs - if you try to remove spring alltogether and push CCT back you will see that it requires very serious effort to "fold" them. So, it takes some time for CCT to retract even when spring broke - it is what that worm screw does.
Somewhere it started to rattle, but I am sure it is easy to miss, especially with sound VTR makes ;)

Actually, it can be a little confusing. Honda calls the cam chain tensioner a "tensioner lifter" and calls the cam rail a "cam chain tensioner." If the latter fails it will fail catastrophically. But the tensioner lifter (what everyone else calls the CCT) almost always fails with symptoms.

Re: What should I do with my CCT's ?
 

Perhaps, but it still sucks!

Alright. I just bought new "tensioner lifters". Honda superseded the earlier model with the updated version for all years. I'm going on a four day super tour, my tensioners have 20k miles, and better safe than sorry. I guess my reasoning is that if a spring breaks, there is no warning and would result in a sudden loss in chain tension.

Re: What should I do with my CCT's ?
 

Though probably paranoia I started hearing the ticking around 3K rpm a few months back and it was getting louder. I figured either the CCT or it needed a valve adjust. With nearly 20K on my bike I decided to replace the CCT. I specified the part number (14520-mbb-013) to the shop and they have orange dots. Sounds like they are updated design as mentioned earlier.

Now to hijack the thread. I struggled with whether to do this myself or have it done. While checking the valve clearance and replacing the CCT seemed easy I was worried about removing cam essentials and measuring shims to thousands of an inch for adjustments. My reasoning to take it in was-Why take the whole thing apart to check the valve clearance if you're not prepared to adjust if necessary-? Turns out the valve clearance was fine and checking them was the bulk of the cost for labor. Ouch.

Which brings me to my question. Understanding every case is different, about how often have folks had to adjust the valve clearance? My new reasoning would be -It's OK to spend 4 hours checking the valve clearance because it's unlikely it will be out of spec, and in the event that it is, it's going to cost a bunch to get it adjusted anyway.

Looking for a little future maintenance advice.
Thanks!

I installed my new tensioner lifters last night. Instalation takes 45 minutes and requires removing the airbox for the front. Don't forget to be at top center for each cylinder.

The main visible difference in the parts is that the head of the lifter is now a dense rubber, rather than steel. Indicating to me that vibration may have been an issue contributing to early failure of the 1st generation parts.

I don't know if they would have failed, but I will have peace of mind on my 4 day trip, starting tomorrow :lol:

Dutch, measurement of the valve clearance is straightforward if you have a shop manual, some mechanical ability and a feeler gauge. The valves rarely need adjustment, so it makes sense to check them and keep the shop monkeys away from your bike (IMO).

Re: What should I do with my CCT's ?
 

The steel top of the old tensioner is removable. I placed that on the new one.

Number 6 on the drawing.
I realy think it should be used

Actually this part is not coming with new CCT, it need to be either ordered separately (but it never wears out, so) or taken from old CCT to new one.
If you will remove that metal cap from old CCT you will find that it actually sits on exactly same rubber cap. And this part is a "must", otherwise you increasing chances of CCT faiure, as tip of CCT pushing agains open-loop camchain guide-tensioner, and it must be round and and protected from wear.

Wow. I didn't even think of that possibility. thanks for saving my A$$!! I should have looked at the assembly drawing. :oops:

I guess I should change the installation time to 1.5 hours.

I got pistons for my Kawi from Orient, I think. I liked them. Lots of BOOOST!

More to the point: I believe I have the APE adjusters. Is there anything I should worry about? Where would I find the procedure for adjusting them?

Thanks!

If they're not making noise there's nothing to worry about.
If you wanted to adjust them,
loosen only the lock nut,
with the engine running,
turn the adjustment bolt counter clockwise till it starts to make noise (you'll feel it though the bolt more than hear it)
Then turn the bolt clockwise till the noise just stops and tighten the locknut.
