The thread on the APE MCCT bolt is 14TPI, .071" per turn and .012" per flat. The notches on the ACCT are around 1mm/.040". So if my foggy math is close this Saturday morning, I would say a quarter turn/.018" is less that 1/2 click.
Thanks, I set it last year when CC was new and ACCT was at 4 or 5 clicks. I felt like it needed half a click and that's what I was trying for without pulling the ape and putting the auto one back in for reference. A half click a year will get a lot of life out of the CC.
I started adjusting mine with the engine idling and a 5/8" wobblysocket/open end wrench. I found that turning it in until turning anymore doesn't change the sound is just right. If that makes sense?
Hi Guys, When I installed my APE recently with only 1400 miles on the 08 and 4 clicks on the ACT, I kept rotating the engine with spark plug out and noticing the distance at chain "tension" it wanted to push the MCCT away from the block with various plunger adjustments. It seemed at about 2-3mm away from block at chain max tension the MCCT would still contact the CC guide very gently when rotated to "slack" and therefore when MCCT was pushed back in against the block for mounting the pressure on the guide was pretty light at CC tension position. The engine is quiet. I agree, I think light guide pressure will lend itself to long CC life.......and I don't rev much above 5 grand in most situations so I'm hoping I'm not "whipping" the chain much.
