If the tensioner was too tight the chain might wear a bit more on the chain guide. The guide is aluminum with a rubber coating, heavier where the chain rides.Well, it did take some effort to reinstall the ACCT when I did it early in the season. At the time I just figured the pressure was the result of the spring pushing against the chain guide.
So please help me understand what might have happened instead, and why it needs to be "reset". Does the spring somehow get locked in the extended position once it's removed? If so, why? What sense does that make engineering-wise?
Both of the MCCTs are installed now and have been for the past few months. I still have both of the autos in a ziplock. But I'm worried about that front cylinder because when I went to tighten the MCCT on it yesterday, I kept winding it in without effect. I kept expecting to meet more resistance; maybe even make the idle drop (which happened the first time I dialed them in) but nothing happened. I didn't dare keep going so I quit and called it a night. I still don't dare actually. But it's bugging me no end wondering if I really effed something up in there.
