Does anyone know where sells them in the uk? I've tried ebay and google and it only turns up guides on how to swap them out and youtube vids. :(

Also, does leaving it to rattle cause any damage?

My bike only rattles at 3krpm when warm, strange I know.

The intention of this thread is to clean up the F2 section of the never dying CCT reposts.

Almost all Honda’s have a few common shortcomings in their design, some of these include charging systems and most commonly the Hydraulic Cam Chain Tensioner (commonly referred to as the CCT).

This tensioner is actuated by oil pressure, and while it is a great concept it is prone to failure.

The most common evidence of a failing CCT is a prominent rattle or ticking noise coming from the right side of the engine on a cold start (often mistaken for a noisy valve train), and the noise will go away when the engine reaches operating temperature and oil pressure is revived.

A completely seized CCT will always rattle.

In most cases replacing the old CCT with a new OEM hydraulic tensioner will yield unfathomable frustration when you go through the trouble of buying and replacing it - and the damn thing STILL rattles.

The BEST way to cure the problem is to purchase an “APE” manual CCT found on Ebay and other online retailers for about $50-70. You can also try your local dealership, but expect to pay more.

INSTALLATION INSTRUCTIONS:

Step 1: Remove right side tail fairing and right side lower fairing

Step 2: Locate the OEM CCT

Step 3: Remove black engine mount bracket if obstructing access

Step 4: Remove the 2 bolts securing the CCT to the engine

Step 5: If equipped with a steel gasket, clean gasket and save. If a paper gasket is present, scrape off gasket material being careful not to drop any into the opening or damage the gasket surface.

Step 6: Back the tensioner bolt all the way out on your new APE manual CCT, and apply a dab of white lithium grease or assembly lube to the end of the bolt.

Step 7: Install the new CCT and steel gasket or new paper gasket and secure it with the 2 bolts from the OEM CCT.

Step 8: Thread the tensioner bolt in FINGER TIGHT until your fingers cannot turn it any further (never use a wrench for this step)

Step 9: Lock the tensioner with the lock nut

Step 10: With the transmission in neutral and a cold engine, start the bike up

Step 11: If the rattle is present, unlock the lock nut and thread the tensioner clockwise until the noise is gone, then thread clockwise ¼ turn further

Step 11B: If the rattle is no longer present when engine is first started, unlock the lock nut and turn the tensioner counter-clockwise until the noise returns, then thread clockwise until no longer present and ¼ further

Step 12: Lock the lock nut, turn off the bike and put fairings back on.

Im having a difficult time looking for the CCT on my F2, Can someone post a picture please?

Give me a couple of hours and I'll get you a pic. If you sit on the bike, it'll be on your right side, close to your knee. Easy to spot if you have the plastics off the bike.

CCT adjustment..
 
I have a APE cct, and I followed the adjustment instructions to a Tee. But now i am wondering what the symptoms are of over tightening the CCT. Im pretty sure that i havent, but i would just like to know. thanks

I find when I pull the clutch in, the rattle stops all together. Doesnt appear at any rev's even if the bikes hot or cold.

Ive heard the rattling could be a leaf spring.

Can anyone back this up?

Sand.Man Jun 25, 2009 12:02 PM

A leaf spring? Does your CBR have a pickup truck rear suspension?

You're hearing the clutch plates rumbling, that's all.

tigertim20 Jul 3, 2009 01:15 AM

2 questions, 1, clutch plates rumbling, is this something to worry about? mine does it.....
second, i get the rattling on a cold start, goes away after 1 minute or less. it only happens sometimes. should i be putting this ape thing in? if so can you tell me where i could buy it in colorado? my father in law lives there and i could get him to send it to me. (i live in new zealand)
