• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

CCT idea

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.:excuseme:
 
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.

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)

ok, consensus is this idea sucks. I guess that explains why no one has done it before. thx
Click to expand...

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.
