In the middle of tackling all of my wiring in the 6.2 M211 retrofit project. My knowledge of anything electrical is limited but I know enough to realize that fuses for big power drawing devices such as glow plugs, fuel pumps and lights are a must. Do I need a fuse in between the Ignition...

There sure are a lot of GMC guys coming out of the wood work these day's. I had a great idea, it is a copy off another forum I was on many years ago and am still on today. We've all come to know one another on here, some of us have even made best life long beer buds when distance was not a huge...

Anyone know how the 700r4 would work on 24 volts? I know things like switches work on either 12v or 24v and many are sold labeled as such. However the 700r4 is full of hydraulic solenoids which I am sure need to see the voltage they are wired for (12v). I guess the proper question is how do...

This is the 2nd time typing this out since I accidentally deleted it. So bear with the lack of enthusiasm in information listed below. The M211 and M220 trucks use a Bendix AIR PAK model # 2500685 It is unknown if this is the same model used on M135's. For those who are installing 5 ton...

I am looking for a guy with a lathe who can machine extra piston ring grooves on my York 210 compressor piston's. I would supply the ring's of course. This is for my M211 project. Pistons are around 2" in diameter and are aluminum. Course I never thought to check how much my local NAPA would...

I have a mission for a fellow GMC owner. I need to know approx how many braking applications one has before the air compressor governor kicks back on to recharge the air tank's, during stop and go normal city driving. The mission should be simple, just count the number of times the brake...

This is a great write up I found while doing some searching today. Disassembly, no spin lockers installation, how some of the parts look, etc. Military_Axle_Swap_2

Finally have myself a printer, scanner, fax, copy machine to play with. Gaskets for the GMC air compressor. Don't have the specs on all the other gaskets but the original black head gasket is made of fiber/rubber material and is .020" thick. You can probably get away with any thickness (within...

I have the chance to pickup this model compressor on the cheap, though it is an older unit made in 1995 or so. Would this be large enough for backyard sandblasting and running air tools? http://www.amazon.com/Jenny-Compressors-GT8HGB-30T-Stationary-Compressor/dp/B0054PL9LU

Each paragraph corresponds with each picture from L to R -Here is our candidate. Full of rock hard grease, leaky gaskets and plugged inlet and exhaust ports. They are very easy to fix! -First remove the inlet hose barb and exhaust fitting -Remove these 6 machine screws -Gently pull the left...

I've always been fascinated by torque dynamics and this online calculator is really cool. It tells you the recommended torque and max torque for any given bolt as well as the clamping force you can expect. It has both SAE and Metric tables. FUTEK Bolt Torque Calculator | Bolt Torque Calculators

A true act of charity should remain anonymous, or else it is not charity anymore. Therefore, I will just post the following excerpt from a book I was reading this evening and how it pertains to M1010Plowboy. A darn true friend who it has been an honor knowing. And I quote: "There is nothing...

I recall seeing some 6.2 or 6.5 motors on GL with heat shields on the headers. Were these standard on all HMMWV's? Just a 6.2 or 6.5 thing? I think they look great and take some heat off the GP wires which is always a good thing.

I am willing to bet most of our trucks have some weatherchecking on the tires. We all know you run the best tires on the front axle, that is just common sense on a large manual steering truck. This question pertains more to the duals. As I see it, duals are great because it allows you to run...

Many of us don't give them much thought. The nuts used on our trucks are Mil-Spec and are known as "Flex Nuts". Many hardware outlets do not carry them. They are also very expensive. So, take care of your nuts. There's probably a few thousand dollars worth of them on your truck. I've probably...

I am installing a York 210 compressor on my 6.2 M211 project and I got to thinking, why not put this compressor on the M35 style trucks too? It would be a huge improvement over the stock Midland unit. They have their own oil sump, are rated for 6000rpm, cheap parts, electric clutch, should make...

As before, each paragraph corresponds with each picture below. From left to right. I disassembled, cleaned and reasembled this compressor last year since it came to me seized up from sitting for so many years outside. A hone job and a little rust removal had it back in action, the bottom end...

Each paragraph below corresponds with each picture. First you'll want to take down your windshield. Start by removing both flathead screws from the window locking arms. There are 7 bolts that secure the windshield pivot to the windshield cab frame. Remove all but the center most bolt. With...

Anyone else pickup HAM radio operators on their computer speakers? There's this one guy who I think is in the Grand Canyon area who is annoying as ever. The voice is as clear a day, but I cannot for the life of me figure out what this guy is talking about when he speaks. I thought truckers slang...

Alright, we know NAPA has the GMC wheel cylinder cups. Part # United 14451. Does anyone know if they carry the pistons, expanders and push rods too? Guess I'll take a trip to NAPA tomorrow.
