I doubt you will find much useful information available in the first gen. diesel 4L80E TCM it was very basic with a couple of analog readings (RPM) I don't think it even had a TPS or any pressure readings, at that time they relied on trouble codes almost exclusively which you do not have to have...

This is one of the local auctioneers my wife works for so I can do a cursory inspection, looks nice in the picture, looks like supplemental armor doors. https://www.elcoauctions.com/auctions/6/lot/29-2002-am-general-m1097a2-humvee-4-door-truck-body Click on upcoming auctions at the top of the...

I have not noticed any issues.

I am not positive but this one looks like the one I ended up using, HPG calls this a 100/200A serpentine pulley...

Actually I have one of those laying around here somewhere, When I bought my GEP turbo motor which obviously had very few miles on it I unfortunately decided not to pay the $500 extra for the starter and 200A alternator, so the guy sold me a serpentine pulley because I was going to convert my...

You could machine it down to align with the belts, allot of money to be grinding away on though..

Must just be a wrong pulley, I don't think there is any difference in the pulley lineup between the NA and turbo on the majority of the trucks.

You don't have to have a clutched pulley, as you know they do fail, solid ones never fail.

That is a non clutch (solid) pulley And that is allot of money, have you put a want in the classifieds???

If the fuel leak is outside the valve covers then it is likely the fuel return lines, not a big issue

In the sticky it is clearly a 1999

There is a sticky near the top of the HMMWV forum for serial number/year of manufacture Also what the odometer says means almost nothing in the HMMWV world as the speedometers are swapped out very often. Take your time and look it over very carefully. If you decide to buy it the first thing to...

Welcome to the forum!!

The hydro-boost is not likely causing the steering box to leak, the noise you hear is the pump having to work. The Hydro-boost can leak, it will fall to the ground behind the drivers side front tire, the steering box usually to the inside of the driver side front tire. I always try to caution...

Make sure to wear a heavy long sleeve shirt when replacing the hose,

Why are you going to R-R the clutch? if it is not leaking then “let sleeping dogs lie”

Once you remove or loosen the belts the fan/water pump will turn so you can access the hose fitting, you only need to pressure up the clutch to align the cap screws to remove the clutch.

Here is a link to modifying the waste gate controller to make it adjustable, it shows clearly the inner workings of the waste gate controller. https://www.steelsoldiers.com/threads/turbo-waste-gate-conversion-to-adjustable.209441/

The waste gate controller is simply a spring, the waste gate opens when there is enough back pressure on the gate to compress the spring so most of the time the gate is closed and is closed when not running so if it is stuck it would likely be in the closed position, the spring is pretty strong...
