I am the "next poor sod" lol.....thanks for the pics for sure...After I figured out exactly what I was doing I was planning on taking pictures with measuring devices to make it easier for the next poor sod who tries to do this.
I've only found a couple threads that have had useful information, mostly over on G503.com, along with this gallery http://galuba.org/hummer/index.php?spgmGal=AC&spgmPic=59&spgmFilters=#pic
I finally got the correct bracket a few days ago, got the condenser installed.I am the "next poor sod" lol.....thanks for the pics for sure...
Engine is a GEP that was rebuilt and installed in the truck in 2009, so likely only one decade old.Sounds like something is out of round?? Magnetic base and dial indicator on the pulleys one at a time with belt/s off. Crank shaft a little more of a pain, wrenching it around. Check for loose or cracked brackets power steering pump, alternator, you got the idea. Changing the harmonic balancer not a bad idea for many of the trucks IMO.
30 year old rubber anything could use a changing, CAMO
whats the tensioner doing at 1500 Rpm...its, easy to see failing dampener or crank pulley, just look while running, should be no wobble. Don’t look for perfection on the red dot setup, this is not a precise OEM solution.Engine is a GEP that was rebuilt and installed in the truck in 2009, so likely only one decade old.
with as much movement as there is, I figure it's probably one of the larger pulleys. Haven't put a dial indicator on any of them (i think I have one somewhere, but haven't used it in 5 or more years), but with as much as it moves the tensioner pulley and the crank pulley being the only pulley I can't spin over by hand to check added to the rubber isolator design plus the balancer there I won't hurt anything by changing them.
I have the crank pulley and harmonic balancer on order now. Not sure if it is normal for these at idle but the engine does seem to have a bit of a shake as well (more than I am used to seeing, though my main comparison is the 7.3 turbo in my F450) so I figured it probably can't hurt.
There is a decently hefty piece of ABS plastic that bolts to the bottom of the condenser. Looks like it's designed to be able to bolt to armor pieces or something to the front and rear, but isn't required to in order to be protected.Can I ask about the protection under the fenders as it wasn't clear. Once installed is there protection of the fan and exchanger from rocks being kicked up from the tires?
