Quick CCT fix

RSJ · 07-13-2008, 2:19 PM

Still waiting for the new cct to arrive in the mail but wanted to ride today because the weather is perfect here....

Anyway, I took a 6mm bolt and lock nut, took the sealing bolt off the existing cct, tightened the tensioner with a screwdriver so it was tight and torqued down the 6mm bolt and tightened a lock nut . Worked perfectly. Proboably a good item to have in a tool kit for long trips- nice and small too.

Im new here, if somebody already came up with this, please disregard. Havent figured out how to search here yet.

Thanks for the tip. Has been tried in the past by a couple of people, just waiting to hear back from them about the long term use for this CCT mod.

As the person who posted this idea I can assure you that I did not do it on my bike.

I have just got around to doing my CCT last week and I went with the mechanical adjuster from the US.

I did however have a good look at what is going on with the tensioner and believe I know what the problem is.

IMHO the movement that causes the marbles noise is caused by the tensioner extending far enough that the shaft that moves out to push on the chain guide is able to flex in the vertical plane. In short it wobbles.

If you get a screwdriver and hold it in the tensioner slot you will feel the movement I am describing as vibration. Interestingly it seems to be strongest at about 4000 revs. I think it may be a harmonic thing.

If you push hard enough with the 6 mm bolt bad things will happen inside the tensioner (the plate on the end where the circlip holds it together) so much for that good idea. So RSJ please don't tighten it any more, it should be OK if its running in the position its in now.

So what to do? Get the APE or Honda improved model and replace it.

By the way, I dont think any thing actually wears out it is simply the chain settling down enough with a bit of wear that causes the tensioner to extend far enough to cause the problem.

It would be interesting to know how quickly an unimproved tensioner fails if fitted I am sure there would be a lot that did it very quickly if I am right.

Purchased a new new CCT last week and i'm going to attempt the RR. Instructions / manual indicates that you turn the tensioner shaft fully in (clockwise) and secure it using the stopper to to prevent damaging the chain. What if you don't have a stopper tool or are you suppose to use the stopper tool from the new CCT. Thanx

You don't need the stopper tool, a small screwdriver can also be used to back out the plunge while securing the CCT.

I want to make sure we are on the same page!! Are you talking about removing or ininstalling the CCT because you said "secure the CCT"

Thanx

I'm talking about installing the CCT. You can back out the plunger (away from the cam chain) with a screwdriver, keep it there while you install the CCT and tighten the two bolts Then it is just to remove the screwdriver and let the CCT plunger work itself inwards. It can be done with two hands, even though it would be easier with the help of third one

My question is when you are removing the old CCT, Instructions / manual indicates that you turn the tensioner shaft fully in (clockwise) and secure it using the stopper to to prevent damaging the chain. What if you don't have a stopper tool or are you suppose to use the stopper tool from the new CCT.

Thanx

When I did mine last year, the plunger (stopper/holder tool) was used to hold the plunger IN while installing the tensioner. Only after securing the two bolts, then I pulled the tool out to release the plunger up against the chain guide. Very easy to do, only about a half hour of total time due to removing the right side plastic. No problems or noise since. Check out Warchilds post on this subject on the home page. Cheers.

It is just to remove the old CCT by unscrewing the two bolts, you don't need to worry about the tensioner shaft at removal. The center bolt covering the tensioner can be in place during the removal.

The stopper tool on the new CCT shall not be removed before the unit is bolted to the engine.
