Sorry I didn't include the vacuum value. Another trouble shooting method is to bypass the throttle valve and just go direct from the vacuum pump to the modulator on the transmission. It will shift so fast and smooth that you will be in 3rd gear at 25 mph and never feel a shift if you drive...

Just plug a vacuum gauge into it. It is real easy just plugging into the line at the throttle valve.

If it is the power steering bolt behind the pulley. You will need a thin 15mm open end wrench to tighten it. Snap-On fits but Craftsman and Kobalt don’t in my experience.

I didn’t get a chance until after dark tonight. I think I got what you wanted. Look closely at the rear of the fender cut. To me that is the most important. I have never had it rub with 315/75R17 BFG tires.

I will have to measure from the screw hole of the side marker light tonight to get that dimension. If you look real close at the rear there is an angle cut off visible from the outside. Most of the cutting was on the inner part. I will try and take pictures of that too. I did not move my...

I found I actually didn't take any pictures while cutting the fenders. So I have the pictures of the truck already posted that show the fenders on it and I have this picture of after I painted them:

I like that brake conversion and have tried to figure out a way to do it with 8 lug rotors. I had a 2wd 1984 Diesel 3/4 ton Suburban before the Cowdog 4x4 3/4 ton. I was also driving my M1009 daily. I never drove the Cowdog with stock suspension. So, all I can do is compare the ride of a...

Change a word or the order of the words for a search and things not seen before sometimes pop up. That happened to me yesterday. This is a very technical article about diesel timing theory: http://www.maxxtorque.com/2009/03/diesel-timing.html It also answers the questions I had about why the...

With gasoline engines I used to use a timing light to get to spec and then a vacuum gauge to tweak to highest vacuum from that. I know too far advanced will cause hot start issues and maybe pinging with a gas engine. What I don’t know and have not been able to find out is what happens to a...

It was nice to see everyone again. This is the only picture I got with the 3 Dueces in it:

Check around your bleed screw at the top of the secondary filters. I had one crack there and let air in once. The in tank pump is my guess as well by the way.

Something else to remember is that every single NA 6.2 seems to be different from every other one. I have a pair of M1009's that at one point in time were daily driven every day. There was a NA 6.2 2wd Suburban driven every day and my NA 6.2 M715 that got driven a few times a week. 4 6.2...

I'm glad this thread came back up. It has been hovering in the back of my mind since the other day. I get the feeling we are speaking different languages and not answering what you are asking. Atmospheres to me is a term used in aviation to talk about manifold pressure. Standard pressure is...

I built the truck with high speed comfortable interstate driving to get to places where pavement isn’t. Overlanding is a neat idea that I want the truck to be able to do. I think I have the high speed somewhat efficient travel in comfort checked off. Some of the off-road equipment has been...

Everyone drive safe. I will be there in the Cowdog after 1800 most likely.

If the oil is correct, if the oil warning light is functioning if it isn't internal engine related. Check ALL of the power steering pump mount brackets and bolts. Then, check the torque converter bolts. Sometimes they work loose and make a gut scrambling knock noise.

No argument from me that when working correctly, computer control is far better. Like you, I enjoy the "art" of getting something just right. Dynamic timing of a 6.? mechanical pump seems to be part art, part full time researcher and part black magic.

The 2 leaf Chevy 3/4 ton front springs and the 3 leaf Chevy CUCV M1009 front springs have the exact same ride height was my experience when I swapped from 2 to 3 on my Suburban. The 3 leaf pack was available on the "snow plow" package and the CUCV trucks. Stiffer ride for sure. Which I like...

So, I found another data point. This article was written by a guy converting to a DB2 pump from a DS4 electric pump: http://www.kozykalpacas.com/DIESEL/DB2%20Conv%20Guide.pdf He uses a MT1480 tool to set his timing. He claims the 6.5 timing tab has a 30° offset. Which is what I guessed last...

It isn't a linear power curve or relationship between fuel increase and power increase. Mainly because of how slow diesel fuel burns. At least with the indirect injection 6.2/6.5 engines. I don't know about the direct injection engines. Theoretically a 110 hp NA 6.2 could make 200 hp with a...
