Manual timing chain tensioner info

[TOS]

What n how do u use to hold the chain tension when u remove the cct
Thank you

After removing the clutch cover, I just tightly wedged the plastic end of a screwdriver between the crankcase and cam chain to hole tension while removing old tensioner and installing the Graves.
This worked good for me.
Good Luck

Just stick something between the guide and case. Then remive the old cct and stick the new one in. Graves is nice but the oil gallery is just to lube the cct so any manual one will work.

No oil is necessary. I would remove the clutch cover yes

I found the pic I took when changing out my clutch and CCT. Make certain that whatever you use to wedge the crankcase cam chain guide tight, is in good and solid so it doesn't dislodge, while you remove the CCT and install and adjust the new CCT before you remove the wedge. Good Luck, hope this will help.

There are a few videos on how to adjust a manual tensioner on YouTube. I have never seen one on a Tenere, but search for graves tensioner or manual cam chain tensioner install and you will find a few R1 videos which is exactly the same.
The biggest issue with the Tenere is the 270 degree crank which doesn't really have a spot where there isn't tension on the chain. Because of that there is a real possibly for the chain to skip a tooth if you are not very careful and keep tension on the chain when removing the stock tensioner.

Some other members have posted up how they did theirs. Search around and there are some good posts on how to do it. Probably the safest way is to plan to remove the valve cover and check the timing marks after you are finished. If it skips you run a real risk of serious damage, so be 100% before you start the bike.

Here is a link to a members site where he documents his procedure.. Scroll down the page an you will find the section on cam chain tensioner replacement.

Yamaha Super tenere manual Cam Chain tensioner, valve adjustment re-write and moar findings!!

I’m currently going through a friends bike front to back. It’s sitting at 59 thou km of fairly hard use. No maintenance, except oil and filter. Earlier I posted about the inner shaft…

I did a graves install in the fall when I put my bike away for the winter, so I will give my method.
As mentioned tension must be maintained or serious damage can occur.
You need a tensioner. I chose Graves, but APE makes a good one or there are tons of cheap no-name versions out there. Make sure the tensioner locknut is loose and fully retract the tension bolt.
You need a tensioner gasket and a clutch cover gaskets well.

Put a socket on the end of the crank and turn the engine over to align the timing marks.
I chose to make a spacer to hold the cam chain tight. This way I didn't need to remove the valve cover. This greatly reduces the time needed to complete the job, but it comes at a risk.
Another member had a neat idea to make a spacer that fits behind the chain guide. I copied his idea and used a short bolt and nut. It fits snugly behind the chain guide and keeps everything nice and tight. (The zip tie in the pic is just for easy removal after.) Then remove the old tensioner and install the manual one.
After tightening down the mounting bolts, slowly turn in the tensioner until you feel it snug up. I tightened it by hand as much as I could. Then remove the spacer behind the cam chain guide.
Put your socket and ratchet back on the crank and slowly turn the engine over. While doing this use your other hand to hold tension on the the cam chain tensioner bolt. You will find as you turn the crank there will be a few spots where there will be a bit of slack and the tensioner will turn in a bit more.
Don't force it too hard just nice steady hand pressure. Probably after one full turn you won't be able to add any more.

At this point back the bolt out 1/2 turn and tighten down the locknut.

When finished turn the crank over a few more times by hand to make sure your chain didn't skip. Last thing you want to do is hit the starter and bend some valves.

Reinstall the clutch cover and you are done.

I’m so glad I found this! I was so dreading removing the valve cover. And I was doing the clutch basket swap anyway! Now let’s just hope I set the tension correctly.
