Removal of the LT4 stock supercharger
OK, So the extraction is done. I was lucky. I have many things to report. 1st I had about 4000 miles on the car when I finally decided to install my MM Wild CC. Everything was going smooth on the install, even though I haven't really picked up a wrench in about 11 years (I'm 59), and then disaster. The torque wrench I bought did not do it's job properly and click on 10 Newton Meters of Torque. And there are reasons I kept on tightening. Nevertheless, I should have backed it out and started over, cause I had a hunch something was amiss. Maybe because of the lack of wrenching in recent years it just didn't come to mind. So current situation was. Broken bolt in the number 10 hole.
I must put that when the bolt broke, I didn't thoroughly finish the reassembly. Parts were just in place, Like the airbox to TB tube, so they could be easily yanked off when it was time. And the time was this weekend.
Removal of the Supercharger
Yesterday I started on the preliminary stuff. And I must also note. I didn't know the position of the broken bolt, was it above the head or below. So I was a bit scared. Because if it was above, how was I going to slide the supercharger under the wiring harness like everybody else did on youtube?? So I Pulled the belt, took off the air box tube, yanked off all the PCV hoses, unhooked the electrical connectors on the right side of the supercharger. And started looking for wiring harness slack. I undid the Airbox (I just wanted to, exploring!), I also yanked the plastic Coil pack cover on the RHS (exploring) and unhooked all of the wiring to the coils. I also unhooked the other side as it seemed to give me a little harness movement. I also unhooked the clip behind the supercharger. I need to note once the bolt broke a few weeks ago that I did not re-anchor the wiring harness to the supercharger, but slack was still an almost nonexistent precious commodity. I also yanked the upper exhaust manifold heat shield (exploring). Also, while I say exploring, you all must understand once again that there is NO SLACK on this RHD Camaro wiring harness. It is very tight against the supercharger. And I see people sliding the Supercharger under the wiring harness and I'm wondering how I'm going to be able to get enough slack just to get the guiding pin out. So I was undoing many of the parts exploring ways to make slack or get better visibility on how I would make slack. At the end of the day, I was still wondering how I was going to slide the supercharger under the harness. But before I turned in, I decided to pull the Snow Blocker.... This is Thailand, It's never snowed here ever since man has been on this planet in our current form. So I pulled the top front cover and yanked the damn thing out.
Day 2:
I'm getting more desperate and serious now. I noticed the tie downs on the left side of the supercharger. I pulled the one mounted to the valve cover, but not nicely, I need a new one. and I cut a tie down next to the fuse box, I need another new one. This made a huge difference. Also, I made sure all electrical connectors on the right hand side of the supercharger were unhooked (I had left one). Then after wrestling with the wiring harness, I'm noticing some decent slack. Then I think maybe I can pull this wiring harness over the snout of the supercharger. This would be too good to be true. So I unbolt the vacuum that opens the supercharger valve (also remove the tubes so they wouldn't be damaged), more on this later because it applies to another thread, so I could flip it to the other side (3 o'clock position). With all that done, I'm confident I can go over the snout. I removed the dexcool hoses. I put a cut off finger from a latex glove to seal each one (rubber band to secure it, saw this tip on youtube). Then lastly I pulled all the bolts on the cover and then the supercharger except number 7. Number 7 bolt I taped about 2 inches out so it wouldn't slide back down and interfere with the removal process. I then lifted the front of the supercharger and I noticed the bolt broke above the head by a 1/4 inch (Thank You Jesus!! No drilling and easyout required, just careful use of vise grips). So I then began to summon enough slack to slide the wiring harness over and under the thottlebody and the pulley. It was tight, but not dangerously tight; It worked!!!. So now I could lift the supercharger straight up an inch then move slightly forward then up and off. And it worked perfect. Once off, with the help of my wife, I taped up the intake ports on the side I was pulling the broken bolt out of and I put a plastic bag over the other side. Then I removed the broken bolt with vise grips very carefully, and there was a lot of metal slivers. So after the removal, I got some tape and patted down the entire area to pick up all slivers. Then I pulled the tape and carefully cleaned up the ports which were loaded with oil. Also inside the ports are brown with oil. You definitely want a CC immediately. I actually am going to ask some professionals what I can do to clean all this up if it's possible. Then without thinking my wife and I put the supercharger back on with the old number 7 bolt still taped half way in. I can't believe I did this. I said I would concentrate... But she was in a hurry to leave and she was like, lets put it back on so I can go... And I said, "UHHHH OK." Damn I'm pissed, Idiot. I haven't bolted it down as I don't have the new bolts yet. It's just sitting in the correct position waiting for the new bolts with a plastic bag on top of the supercharger to keep dust and stuff out. I should get the new bolts tomorrow. But because I didn't order the gaskets, I think I'll leave the old number 7 bolt in there and be very careful tightening it down, unless some professional tells me I must take it back off. I don't want to chance messing up the seals. This is my current position. As soon as the bolts arrive I will bolt it down and finish the install of the MM CC. One thing for sure. I will put much more concentration into reassembly. This actually could have been a total disaster if it would have broken down a quarter inch and stripped the first few rows of threads.
