L83 Camshaft Phaser

We are installing a camshaft in an L83 that requires limiting the vvt motion to 4 degrees. In this video we are opening the camshaft phaser with special tools and adding a 4 degree limiter. We do this to prevent piston to valve clearance issues with the higher lift and longer duration of the aftermarket camshafts.

If I lock it out and take the wrong bolt out does it matter?

[@secondshiftperformance]

Yes because you can let the spring unwind. 2 of the bolts have studs on the ends that hold the spring in place.

@@stevenzansant5645 I destroyed the original part trying to get the timing chain off without removing the pump or pan. Don't feel bad if you wrecked one. The part in the video is brand new and cost me right around $140, lol.

@secondshiftperformance I got the phaser out put the delete wedge in but I took the wrong bolt all the way out and heard something unwind inside I never took it fully apart put the wedge in the one vein n tightend it back up would it damage my new cam if I used it?

@@stevenzansant5645 buy the new phaser. For me I bent the thin reluctor wheel on removal and when trying to straighten it the spring unwound. For the money it is not worth putting it together and having to take it back apart. It is such a big job that the $140 is a small amount in the face of such labor. Replace the phaser with a genuine GM part and feel good going back together just once.
