Cam Bolt Torque
The search function is apparently broken on this forum. I saw a post once upon a time that someone had calculated what the actual torque was for the Cam Bolt. I know the book says 48ft/lbs + 90 degrees. What is the actual ft/lb spec? Also, what is the 2nd time torque spec, if anyone has it? Thanks!

You are correct... first pass 48ft/lbs... second pass 90 degree. The second pass has no torque value. It is an angle value. I know it seems silly, but that's the spec.

I read a thread where someone had calculated the torque for the 90 degrees, and that there was a re-use spec as well. Can’t find it now, and the search function is broken here. Unfortunately while I was using my super smart digital torque wrench that has all kinds of torque settings, it was supposed to be set to ft/lb but decided to do degrees first. Unfortunate you can’t see the screen while torquing in that position. I kept waiting for the green light or beep and it wasn’t coming, I know 48ft/lbs wasn’t that heavy so I stopped and looked, it was set to degrees. So I have no idea how much torque was applied. It recorded I went 58 degrees but that’s more than 48ft/lbs. Exactly why TTY and bolt torque angles are shit. So I guess I am ordering another $40 cam bolt. Since I technically “used” this one.
