manual camchain tensioner

My Harley doesn't have all these FJR drama queen issues...

I might recommend that the automatic tensioner be exercised occasionally. When I removed the intake camshaft and changed clearance shims I noticed that the threaded bolt in the tensioner did not turn smoothly initially. After I retracted and released it a few times the bolt began to take on a splendid attitude. Maybe the bolt, etc. experiences a brinelling effect similar to ball bearings.

You might recommend that...

But it seems to me that in the failures that we have documented here, it is immediately AFTER diddling around with their auto-CCT that things went to hell in a handbasket.

If your cam chain is not making noise - don't f&*% with it!!

If it is making noise, trying to increase the tension via any external intervention seems to be a risky business. So you should definitely strip to your tightey whiteys and don a fresh set of Ray-Bans before attempting that one.

Otherwise, more sane folks would be tempted to actually know WTF they are doing or else get someone that knows vaguely what's going on (and is financially responsible for their actions) to mess with it.



Just my opinion.

note: I have just ordered a new type CCT for my beloved BBBBB. I will be making the forray into canm chain world sooner or later, even though, contrary to my own advice, I have no chain noise (yet). This should be considered in the "do as I say, not as I do" category.

.....and here I was feeling contrite for being what I thought unnecessarily harsh!

Thanks, Papa, for setting the bar...........again.

Sorry to hijack this thread, but I thought I saw someone mention somewhere that the OEM CCT can be manually tightened, but can't find any reference to how. Can someone point me in the right direction please?

You can take the bolt out of the end of the CCT and reach in with a narrow screwdriver to either loosen or tighten the CCT, but there is nothing to keep it there so it won't stay where you put it for long. You have to reach through the hole in the frame to get to the screw and it is very easy to drop that small bolt that goes in the end of the CCT inside the frame. So, if you are going through all that trouble you are better off just getting a new CCT.

Basically, no, it can't be manually tightened, just checked using that screwdriver. Back it off, see if it springs back tight.

(With engine NOT running! And chain cover off and chain retained with zip ties!)

Long winded SOB As a note, my CCT did indeed have the end tabs different widths, others did not. Reading the link will clarify what that means.

I dont know why you would want to go to manual CCT? then your just creating more maintenance for yourself. I would trust the new part # yamaha tensioner. Put it in and forget it your done.

Maybe because the Yamaha unit AS DESIGNED is a total POS???

then your just creating more maintenance for yourself.

What "Creating more maintenance for yourself" are you referring to?

My manual CCT has been in for 24,000 miles now. I've checked it 3 times just for the hell of it. Not because I needed to, but because I wanted to. Chain-slack hasn't changed a millimeter in 24,000 miles since installation, so that means ZERO maintenance.

And, assuming adjustment IS needed, an owner with a lick of sense will make the adjustment when he/she is doing other "under-hood" maintenance, i.e., spark plug change, valve check, etc. So when the tank IS up, loosening a 17mm lock nut and turning a screw 1/4 turn or less doesn't make for a whole lot of maintenance. Filling the gas tanks takes longer!

I would trust the new part # yamaha tensioner. Put it in and forget it your done.

I wouldn't trust the new part # CCT as far as I could throw the FJR unassisted.

All Yamaha did was make the adjusting shaft a little longer, and wound up the adjusting spring a little tighter. Yamaha did NOT address the single, GIGANTIC failing of the OEM part -- it is STILL NOT a zero-return device.

IF the spring fails, for whatever reason, the adjusting shaft can screw itself OUT, and then, if that happens, you're phooked.

Ack!!!! The sky is falling!

What a drama queen. Embarrassed to call him one of my Gen I brothers. Heck, he's enough to drive a man to ride a Gen II.................

Oh don't be so melodramatic, I mean what's the worst that could happen if the spring fails?

Yeah, I probably SHOULD get me one of them Gen II barges. At least they don't have the same POS CCT as the Gen..........

oh yeah........

they do!

Yup! Bingo. Grab the beach towel and sun tan lotion 'cause you aren't going any place else for a long time.

Stock cam chain tensioner modification >

I have installed a 6mm long thread screw in the end of my stock cam chain tensioner . I have also added a jam nut and washer .

The tensioner can be extended manually by inserting a thin blade strait slot screwdriver into the tensioner body and turned counter clockwise on the tensioner plunger . The screw and jam nut are used to prevent the plunger from loosing tension .

I will keep forum posted on how things work out .
