manual cct cbr600ft

[flyingmythos]

I have been told to get a manual cam chain tensioner as mine has started to rattle, I have had the cct out and checked it, seems ok, refitted and all was quiet for 5 mins, now the rattle is worse!! Surely a new cct would put the same pressure on the chain guide thing, so would a manual cct just stretch the chain?

automatic CCT's adjust to account for cam chain wear. they dont move in and out, just out.

on auto ones, the spring can wear out, meaning it doesnt extend properly, causing the rattle.

manual ones have to be set right, but they work better if done properly. they need adjustment fairly often though (like every few thousand miles, depends how you ride).

if you do get a manual one, can i reccomend that you DO NOT buy one from bigccracing... they are dickheads. www.debben.co.uk is your best bet.

Manual CCT's have to be set carefully to avoid excessive stress on the camchain. Most people have them too tight.

Thanks, i'll try to take it apart first to see if I can upgrade the spring, I only do 10 miles a day and don't thrash it so A race billet 1 probably not needed, more like a standard 1. cheers.

I have just finished reassembling the cct, the spring had worn and was spinning round the chamber, i think! I used some metal clasps out of my wifes jewellery stuff and all seems ok so far, no rattles, haven't riden it yet though, will try it 2mo, found a fella that will make me a manual cct for £23 though.

[flyingmythos]

All seems to be okay with the cam chain now, 100 miles done and still no rattles, thanks for the advice.

The CBR600F's engine tends to have a noisy cam chain when cold anyway - mine certainly does, despite having two CCTs fitted by Honda whilst I've had it.

As a general rule, if the rattle disappears as the engine gets warm then it's ok.

My noise wasn't normal, it happened hot or cold and wasn't regular, obviously the spring inside the cct had become tangled and weak but all is okay now (touch wood)

cam chain tensioners have always been a week point in jap bikes, i wouldn't mess around with home made/bodged tensioners its just not worth the risk of destroying your engine.

I remember a guy at the bike shop i used to work in complaining that his bike (cbr600 engined chop) was rattling and that his cct had fff-ed up,

couple of days later he came in bragging how he didn't need to buy a new tensioner because he had made his own from a bolt and lock nut,

needless to say we had a phone call less than five minutes after he had gone asking if we could bring the shop van to collect his bike because the cam chain had just snapped whilst he was over taking sending him and his bike into a fence.

[mattsprattuk]

if the cam chain snapped on the home made one, its not the CCT at fault then is it it was probably too tight.

theyre not complicated. i was considering making my own manual one for the GSXR and the R6, but its easier just to spend £40 on one. if you do get one made, make sure you use an o ring to stop the oil working its way through the threads.

adjusting them is generally easy too.

Manual tensioners are easy to adjust, and only need attention every 5000 miles or so (at least on my GPz750r).
