Jim Warman Posted December 17, 2011 Share Posted December 17, 2011 Well, we had one in the other day..... Kenny got this pic of a 6.7 sporting a V-Mac compressor. The air cleaner is turned 90 degrees and the lid is "altered". The washer bottle is behind the front bumper. The right side battery is moved to below the drivers door... It was in to reprogram tire size and because the washer hose was pinched during the relocation process. I'm sure there are many more "interesting" alterations that we have yet to notice.

cbriggs Posted December 18, 2011 Share Posted December 18, 2011 How would you like to be the guy that has to design that to fit in there? Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted December 18, 2011 Share Posted December 18, 2011 Oh the humanity! I am surprised there was room to do that. With all the extra room on the sides of the block I wonder if it would make sense to mount a pump under the head where the lines would be un-obstructed and run a short shaft to a pulley and clutch at the FEAD belt.

DieselD Posted December 19, 2011 Share Posted December 19, 2011 I was asked to price labor on one of these before leaving the dealer. I took one look at the vmac instructions and when WTF. We ran through the modification and concerns with the customer if they installed one on their brand new 6.7 and it changed their mind. thank god I didnt get stuck installing that beast!

BIGMEC Posted December 20, 2011 Share Posted December 20, 2011 We had a Cat service truck in a couple weeks ago with one. The big rubber air hose was pushing on the pcm connections causing multiple codes and no power. I would like to see one driven off the pto or just mount a diesel powered one in the back Quote Link to comment Share on other sites More sharing options...
Jim Warman Posted January 21, 2012 Author Share Posted January 21, 2012 The installation pictured has a harmonic under certain load/rpm conditions. There is an audible "buzz" in the right front. The steering wheel vibrates, the floor vibrates... phuque - the TRUCK vibrates. And, yes, the intake duct is pushing hard on the PCM connector. Now... you can be relatively sure that it will be the truck that is called a POS and NOT the V-MAC pieces. In our case, I can only return the truck to stock condition (what it might take to "turn back the clock" is up for conjecture) only to find out that the problem lies in an ill fitting, poorly considered accessory that would be better replaced by a portable, gas powered air compressor Quote Link to comment Share on other sites More sharing options...
Matt Saunoras Posted August 30, 2012 Share Posted August 30, 2012 I had one of these a while ago I posted pics of the main engine harness smashed between the compressor bracket and right cylinder head. The end result was a TACM wire shorting out on the head causing a DTC and on one instance blew the cold side cac tube to pieces. I couldn't dupicate the short but I found it when I pulled the harness open Quote Link to comment Share on other sites More sharing options...
