I have 08 610. I just changed the cam chain at 6500 mi as a preventive measure, the stock CCT was 7 clicks out. I also installed a manual CCT. I will have to get up in there and adjust it since the thing is starting to slap loudly at idle when its cold. In doing all this I had the notion of taking the stock CCT and grinding off the teeth, so you have a pressure that stays relatively constant, not ratceting progressively harder as with the stock setup, or getting weaker (needing to be tightened as with the manual CCT) as the chain breaks in or stretches. Has anyone done or heard of this?
The CCT needs to hold pressure on the chain. If you grind off the teeth there will be nothing to hold it steady.
the spring maintains pressure on the chain, the teeth just ratchet that pressure ever stronger. no teeth would allow the tensioner to float in and out and keep the chain at a constant tension, is my idea.
I don't think that's a good idea. When the chain pushes the guide back, there will be slack somewhere else to grind and wear out and slap. Valve timing will change a little too. Big
Cars with non ratcheting CCTs (and non ratcheting belt tensioners) have shorter cam chain/belt life. Mainly due to the fact that the chain is free to flap about as the tension is not always even (differing loads on chain throughout the combustion cycle)
the spring pushes the adjuster out when there is some slack and the rachet holds it in place. With out the racket (teeth) the cam force will overcome the spring and the cam chain will be loose. These adjusters have been used in bikes for decades. I would be looking at this issue from a different angle.
