Honda Cam Chain Tensioner $1.50 Fix - SoFlaSportbikes.com - South Florida's Sportbike Community

what do you think would this work? as i think my CCT is on its way out!!



Honda Cam Chain Tensioners, yes they suck big time but there is a $1.50 fix for the later Hondas, F3 and up. If the CCT has a plug (bolt) at the outer end remove it. Buy a 6X1X30mm bolt and nut . Check thread pitch by placing one bolts thread against the other. They should nest perfectly. Thread the nut on the bolt and install the bolt into the hole that the plug was in. Gently (fingertip pressure only) rotate bolt until it makes contact with the piston. Hold bolt with wrench and tighten nut against the CCT case. Your CCT will now be silent. Why does this fix work? The CCT in the Hondas does not have a ratcheting mechanism. It depends on a left handed threaded shaft that is spring loaded. Due to the locking pitch thread design this shaft cannot back up. Sounds good so far. Unfortunatly the shaft stays in one place so long that the constant vibration wears out the shaft or the nut that the shaft rides in. The shaft gets sloppy and does not exert enough pressure on the chain pad so the chain starts to rattle at high rpm. The bolt fix exerts just enough pressure on the threaded shaft that it prevents the shaft from vibrating and backing up thus eliminating the chain noise. Yes you will have to adjust the bolt but so far I have no historical data as to how long the time intervals are in between adjustments. Maybe some of you big milege people can provide the data. Any way, hope it prevents you from buying a new CCT.

 

meh..probably not.

Maybe someone whose CCT is on the way out can test this theory and post up here?

 

It might work but when my CCT went I replaced it with a manual one and so far its great. I know its high quality, not jerry rigged. And when that noise does start back up I can readjust the manual one and not have to spend another dime. Its worth it in my book.

 

Thanks guys i will think it over ,if i do go for the Mod option i will let you know how it turns out

 

hell, i might be the guinee pig here for everyone.. i lost my end bolt, which is allowing oil to escape.. and my cct is going out, so i will think on this one for the night. if i dont reply back, then i decided against it.. LOL. but i might do it temporarily.

 

I tried the bolt fix since I'm waiting for my manual tensioner to come in the mail. It did work for about 3 or 4 tanks of fuel. Now I have to adjust it again. Its better then listening to that damn noise. lol Can't wait till the manual one gets here.

 

Yea, i decided to do it. I tightened it down pretty snug by hand, with just a dab of lock tight on the threads closest to the end of the cct, then tightened down the nut. No more noise! New cct has come, but doin crazy shifts at work till saturday, so it will have to wait now.
