Second write up for the day...

Well, as some of you are aware the Cam Chain Tensioner (CCT) on these bikes seems to like going on holiday after a while... I had to replace mine so I thought I might write this.

So first up, the new CCT:



The 'Special Tool' that is used to hold the CCT in the retracted position so that you can install it, my new CCT came with this:



The first thing you are going to need to do is take your right hand fairing off.



Remove the toolbox and move the piece of rubber behind it to reveal the CCT



Now take the timing cover off, so that you can see the timing marks - rotate the engine clockwise to align the 'T' mark with the index mark on the housing.



Loosen of the 8mm bolt on the end of the CCT, but don't remove it just yet.

Remove the two allen key bolts from the CCT, When you do so undo them the same amount at a time to try and keep the CCT from twisting in its housing. Once you have undone it remove it from the engine



And take the old gasket out



You can see here the difference between the old and new gaskets, they are metallic and the new one is clearly embossed but the old one has been squashed flat, it's definitely worth getting the new one for the extra $5 it will cost you.



Now you are ready to bolt the new CCT in place, once you have tightened it down good and proper (7 ft-lb for those who can get a torque wrench in there) you can now take the CCT retaining tool out of the back, it will snap into position.



Take the bolt and washer from the back of the old CCT and install it into the end of your new one.

Put the bike back together and your done!

Australians do nice work.....

thanks for the write up.

I have heard for years about CBR's (even the old f4)having had probs w/cct's.

is this STILL the case w/ the 07+ motors?

any info welcome!

Thanks for the write-up. May I suggest at the beginning of your How-To's, list the tools and parts needed to get the job done. That way, I'll know exactly what to get before finding myself waiting for more parts to come in. Just a small suggestion.

I might just do that...

Why not just replace it with a manual tensioner like the ones ape makes? I had to replace my oem one twice on my 929 before I went with ape, never had to touch it again.

Because it's one more thing to adjust, and I don't like the "yeah that's about right" approach to adjusting it. I would rather have a stock tensioner in there that will do its job properly without the risk of the chain being over or under tensioned.

Generally about 50,000km however they have now redesigned it so hopefully it will be a little longer.

Even at if I do have to replace it every 50k, they aren't that expensive and they are bloody easy to put in....

So what it the cct and what does it do??
The cct is your cam chain tensioner, funnily enough it keeps the cam chain at the proper tension which in turn maintains the timing between the cam shaft and crank shaft where it is supposed to be. It also reduces the wear on these components by dampening out any backlash that would otherwise occur.

When you try to line up the marks that are circled do the need to be like yours offset or the T line up with the small circle?

There is a little notch taken out of the housing, that's your index mark.

Then there is the "T" as in Top Dead Centre, that needs to be lined up with the index mark, I just didn't have them lined up when I took the photo...
